Method Detail

close

public void close()

Description copied from interface: PersistenceManager

Close this PersistenceManager so that no further requests may be made on it. A PersistenceManager instance can be used only until it is closed.

Closing a PersistenceManager might release it to the pool of available PersistenceManagers, or might be garbage collected, at the option of the JDO implementation. Before being used again to satisfy a getPersistenceManager() request, the default values for options will be restored to their values as specified in the PersistenceManagerFactory.

This method closes the PersistenceManager.

Specified by:

close in interface PersistenceManager

currentTransaction

public Transaction currentTransaction()

Description copied from interface: PersistenceManager

Return the Transaction instance associated with a PersistenceManager. There is one Transaction instance associated with each PersistenceManager instance. The Transaction instance supports options as well as transaction completion requests.

Specified by:

currentTransaction in interface PersistenceManager

Returns:

the Transaction associated with this PersistenceManager.

deletePersistent

public void deletePersistent(java.lang.Object iObj)

Description copied from interface: PersistenceManager

Delete the persistent instance from the data store. This method must be called in an active transaction. The data store object will be removed at commit. Unlike makePersistent, which makes the closure of the instance persistent, the closure of the instance is not deleted from the data store. This method has no effect if the instance is already deleted in the current transaction. This method throws JDOUserException if the instance is transient or is managed by another PersistenceManager.

Specified by:

deletePersistent in interface PersistenceManager

Parameters:

iObj - a persistent instance

deletePersistentAll

public void deletePersistentAll(java.util.Collection iObjColl)

Description copied from interface: PersistenceManager

Delete a Collection of instances from the data store.

Specified by:

deletePersistentAll in interface PersistenceManager

Parameters:

iObjColl - a Collection of persistent instances

See Also:

PersistenceManager.deletePersistent(Object pc)

deletePersistentAll

public void deletePersistentAll(java.lang.Object[] iObjArray)

Description copied from interface: PersistenceManager

Delete an array of instances from the data store.

Specified by:

deletePersistentAll in interface PersistenceManager

Parameters:

iObjArray - a Collection of persistent instances

See Also:

PersistenceManager.deletePersistent(Object pc)

evict

public void evict(java.lang.Object parm1)

Description copied from interface: PersistenceManager

Mark an instance as no longer needed in the cache. Eviction is normally done automatically by the PersistenceManager at transaction completion. This method allows the application to explicitly provide a hint to the PersistenceManager that the instance is no longer needed in the cache.

Specified by:

evict in interface PersistenceManager

Parameters:

parm1 - the instance to evict from the cache.

evictAll

public void evictAll(java.util.Collection parm1)

Description copied from interface: PersistenceManager

Mark a Collection of instances as no longer needed in the cache.

Specified by:

evictAll in interface PersistenceManager

Parameters:

parm1 - the Collection of instances to evict from the cache.

See Also:

PersistenceManager.evict(Object pc)

evictAll

public void evictAll(java.lang.Object[] parm1)

Description copied from interface: PersistenceManager

Mark an array of instances as no longer needed in the cache.

Specified by:

evictAll in interface PersistenceManager

Parameters:

parm1 - the array of instances to evict from the cache.

See Also:

PersistenceManager.evict(Object pc)

evictAll

public void evictAll()

Description copied from interface: PersistenceManager

Mark all persistent-nontransactional instances as no longer needed in the cache. It transitions all persistent-nontransactional instances to hollow. Transactional instances are subject to eviction based on the RetainValues setting.

Specified by:

evictAll in interface PersistenceManager

See Also:

PersistenceManager.evict(Object pc)

getExtent

public Extent getExtent(java.lang.Class parm1,
                        boolean parm2)

Description copied from interface: PersistenceManager

The PersistenceManager manages a collection of instances in the data store based on the class of the instances. This method returns an Extent of instances in the data store that might be iterated or given to a Query. The Extent itself might not reference any instances, but only hold the class name and an indicator as to whether subclasses are included in the Extent.

Note that the Extent might be very large.

Specified by:

getExtent in interface PersistenceManager

Parameters:

parm1 - Class of instances

parm2 - whether to include instances of subclasses

Returns:

an Extent of the specified Class

See Also:

Query

getIgnoreCache

public boolean getIgnoreCache()

Description copied from interface: PersistenceManager

Get the ignoreCache setting for queries.

IgnoreCache set to true specifies that for all Query instances created by this PersistenceManager, the default is the cache should be ignored for queries.

Specified by:

getIgnoreCache in interface PersistenceManager

Returns:

the ignoreCache setting.

getObjectById

public java.lang.Object getObjectById(java.lang.Object iOid,
                                      boolean iValidate)

Description copied from interface: PersistenceManager

This method locates a persistent instance in the cache of instances managed by this PersistenceManager. The getObjectById method attempts to find an instance in the cache with the specified JDO identity. The oid parameter object might have been returned by an earlier call to getObjectId or getTransactionalObjectId, or might have been constructed by the application.

If the PersistenceManager is unable to resolve the oid parameter to an ObjectId instance, then it throws a JDOUserException.

If the validate flag is false, and there is already an instance in the cache with the same JDO identity as the oid parameter, then this method returns it. There is no change made to the state of the returned instance.

If there is not an instance already in the cache with the same JDO identity as the oid parameter, then this method creates an instance with the specified JDO identity and returns it. If there is no transaction in progress, the returned instance will be hollow or persistent-nontransactional, at the choice of the implementation.

If there is a transaction in progress, the returned instance will be hollow, persistent-nontransactional, or persistent-clean, at the choice of the implementation.

It is an implementation decision whether to access the data store, if required to determine the exact class. This will be the case of inheritance, where multiple PersistenceCapable classes share the same ObjectId class.

If the validate flag is false, and the instance does not exist in the data store, then this method might not fail. It is an implementation choice whether to fail immediately with a JDODataStoreException. But a subsequent access of the fields of the instance will throw a JDODataStoreException if the instance does not exist at that time. Further, if a relationship is established to this instance, then the transaction in which the association was made will fail.

If the validate flag is true, and there is already a transactional instance in the cache with the same JDO identity as the oid parameter, then this method returns it. There is no change made to the state of the returned instance.

If there is an instance already in the cache with the same JDO identity as the oid parameter, but the instance is not transactional, then it must be verified in the data store. If the instance does not exist in the datastore, then a JDODataStoreException is thrown.

If there is not an instance already in the cache with the same JDO identity as the oid parameter, then this method creates an instance with the specified JDO identity, verifies that it exists in the data store, and returns it. If there is no transaction in progress, the returned instance will be hollow or persistent-nontransactional, at the choice of the implementation.

If there is a data store transaction in progress, the returned instance will be persistent-clean. If there is an optimistic transaction in progress, the returned instance will be persistent-nontransactional.

Specified by:

getObjectById in interface PersistenceManager

Parameters:

iOid - an ObjectId

iValidate - if the existence of the instance is to be validated

Returns:

the PersistenceCapable instance with the specified ObjectId

See Also:

PersistenceManager.getObjectId(Object pc), PersistenceManager.getTransactionalObjectId(Object pc)

getStreamById

public oBinary getStreamById(java.lang.Object iOid)

Specified by:

getStreamById in interface oPersistenceManager

setStreamById

public void setStreamById(java.lang.Object iOid,
                          oBinary iObject)

Specified by:

setStreamById in interface oPersistenceManager

createStreamById

public oOID createStreamById(java.lang.String iClassName,
                             oBinary iObject)

Specified by:

createStreamById in interface oPersistenceManager

deleteObjectById

public void deleteObjectById(java.lang.Object iOid)

Specified by:

deleteObjectById in interface oPersistenceManager

newObjectIdInstance

public java.lang.Object newObjectIdInstance(java.lang.Class iClass,
                                            java.lang.String iValue)

Description copied from interface: PersistenceManager

This method returns an object id instance corresponding to the Class and String arguments. The String argument might have been the result of executing toString on an object id instance.

Specified by:

newObjectIdInstance in interface PersistenceManager

Parameters:

iClass - the Class of the persistence-capable instance

iValue - the String form of the object id

Returns:

an instance of the object identity class

getObjectId

public java.lang.Object getObjectId(java.lang.Object iObject)

Description copied from interface: PersistenceManager

The ObjectId returned by this method represents the JDO identity of the instance. The ObjectId is a copy (clone) of the internal state of the instance, and changing it does not affect the JDO identity of the instance.

The getObjectId method returns an ObjectId instance that represents the object identity of the specified JDO instance. The identity is guaranteed to be unique only in the context of the JDO PersistenceManager that created the identity, and only for two types of JDO Identity: those that are managed by the application, and those that are managed by the data store.

If the object identity is being changed in the transaction, by the application modifying one or more of the application key fields, then this method returns the identity as of the beginning of the transaction. The value returned by getObjectId will be different following afterCompletion processing for successful transactions.

Within a transaction, the ObjectId returned will compare equal to the ObjectId returned by only one among all JDO instances associated with the PersistenceManager regardless of the type of ObjectId.

The ObjectId does not necessarily contain any internal state of the instance, nor is it necessarily an instance of the class used to manage identity internally. Therefore, if the application makes a change to the ObjectId instance returned by this method, there is no effect on the instance from which the ObjectId was obtained.

The getObjectById method can be used between instances of PersistenceManager of different JDO vendors only for instances of persistence capable classes using application-managed (primary key) JDO identity. If it is used for instances of classes using datastore identity, the method might succeed, but there are no guarantees that the parameter and return instances are related in any way.

Specified by:

getObjectId in interface PersistenceManager

Parameters:

iObject - the PersistenceCapable instance

Returns:

the ObjectId of the instance

See Also:

PersistenceManager.getTransactionalObjectId(Object pc), PersistenceManager.getObjectById(Object oid, boolean validate)

getObjectIdClass

public java.lang.Class getObjectIdClass(java.lang.Class parm1)

Description copied from interface: PersistenceManager

Return the Class that implements the JDO Identity for the specified PersistenceCapable class. The application can use the returned Class to construct a JDO Identity instance for application identity PersistenceCapable classes. This JDO Identity instance can then be used to get an instance of the PersistenceCapable class for use in the application.

In order for the application to construct an instance of the ObjectId class it needs to know the class being used by the JDO implementation.

Specified by:

getObjectIdClass in interface PersistenceManager

Parameters:

parm1 - the PersistenceCapable Class

Returns:

the Class of the ObjectId of the parameter

See Also:

PersistenceManager.getObjectById(java.lang.Object, boolean)

getPersistenceManagerFactory

public PersistenceManagerFactory getPersistenceManagerFactory()

Description copied from interface: PersistenceManager

This method returns the PersistenceManagerFactory used to create this PersistenceManager.

Specified by:

getPersistenceManagerFactory in interface PersistenceManager

Returns:

the PersistenceManagerFactory that created this PersistenceManager

getProperties

public java.util.Properties getProperties()

Specified by:

getProperties in interface oPersistenceManager

getTransactionalObjectId

public java.lang.Object getTransactionalObjectId(java.lang.Object p0)

Description copied from interface: PersistenceManager

The ObjectId returned by this method represents the JDO identity of the instance. The ObjectId is a copy (clone) of the internal state of the instance, and changing it does not affect the JDO identity of the instance.

If the object identity is being changed in the transaction, by the application modifying one or more of the application key fields, then this method returns the current identity in the transaction.

If there is no transaction in progress, or if none of the key fields is being modified, then this method will return the same value as getObjectId.

Specified by:

getTransactionalObjectId in interface PersistenceManager

Parameters:

p0 - a PersistenceCapable instance

Returns:

the ObjectId of the instance

See Also:

PersistenceManager.getObjectId(Object pc), PersistenceManager.getObjectById(Object oid, boolean validate)

public java.lang.Object getUserObject()

Description copied from interface: PersistenceManager

The application can manage the PersistenceManager instances more easily by having an application object associated with each PersistenceManager instance.

Specified by:

getUserObject in interface PersistenceManager

Returns:

the user object associated with this PersistenceManager

See Also:

PersistenceManager.setUserObject(java.lang.Object)

Returns:

true if this PersistenceManager has been closed

See Also:

close()

makeNontransactional

public void makeNontransactional(java.lang.Object parm1)

Description copied from interface: PersistenceManager

Make an instance non-transactional after commit.

Normally, at transaction completion, instances are evicted from the cache. This method allows an application to identify an instance as not being evicted from the cache at transaction completion. Instead, the instance remains in the cache with nontransactional state.

Specified by:

makeNontransactional in interface PersistenceManager

Parameters:

parm1 - the instance to make nontransactional.

makeNontransactionalAll

public void makeNontransactionalAll(java.util.Collection parm1)

Description copied from interface: PersistenceManager

Make a Collection of instances non-transactional after commit.

Specified by:

makeNontransactionalAll in interface PersistenceManager

Parameters:

parm1 - the Collection of instances to make nontransactional.

See Also:

PersistenceManager.makeNontransactional(Object pc)

makeNontransactionalAll

public void makeNontransactionalAll(java.lang.Object[] parm1)

Description copied from interface: PersistenceManager

Make an array of instances non-transactional after commit.

Specified by:

makeNontransactionalAll in interface PersistenceManager

Parameters:

parm1 - the array of instances to make nontransactional.

See Also:

PersistenceManager.makeNontransactional(Object pc)

makeDirty

public void makeDirty(java.lang.Object iObj)

Specified by:

makeDirty in interface oPersistenceManager

makePersistent

public void makePersistent(java.lang.Object iObj)

Description copied from interface: PersistenceManager

Make the transient instance persistent in this PersistenceManager. This method must be called in an active transaction. The PersistenceManager assigns an ObjectId to the instance and transitions it to persistent-new. The instance will be managed in the Extent associated with its Class. The instance will be put into the data store at commit. The closure of instances of PersistenceCapable classes reachable from persistent fields will be made persistent at commit. [This is known as persistence by reachability.]

Specified by:

makePersistent in interface PersistenceManager

Parameters:

iObj - a transient instance of a Class that implements PersistenceCapable

makePersistentAll

public void makePersistentAll(java.util.Collection iObjColl)

Description copied from interface: PersistenceManager

Make a Collection of instances persistent.

Specified by:

makePersistentAll in interface PersistenceManager

Parameters:

iObjColl - a Collection of transient instances

See Also:

PersistenceManager.makePersistent(Object pc)

makePersistentAll

public void makePersistentAll(java.lang.Object[] iObjArray)

Description copied from interface: PersistenceManager

Make an array of instances persistent.

Specified by:

makePersistentAll in interface PersistenceManager

Parameters:

iObjArray - an array of transient instances

See Also:

PersistenceManager.makePersistent(Object pc)

makeTransactional

public void makeTransactional(java.lang.Object parm1)

Description copied from interface: PersistenceManager

Make an instance subject to transactional boundaries.

Transient instances normally do not observe transaction boundaries. This method makes transient instances sensitive to transaction completion. If an instance is modified in a transaction, and the transaction rolls back, the state of the instance is restored to the state before the first change in the transaction.

For persistent instances read in optimistic transactions, this method allows the application to make the state of the instance part of the transactional state. At transaction commit, the state of the instance in the cache is compared to the state of the instance in the data store. If they are not the same, then an exception is thrown.

Specified by:

makeTransactional in interface PersistenceManager

Parameters:

parm1 - the instance to make transactional.

makeTransactionalAll

public void makeTransactionalAll(java.util.Collection parm1)

Description copied from interface: PersistenceManager

Make a Collection of instances subject to transactional boundaries.

Specified by:

makeTransactionalAll in interface PersistenceManager

Parameters:

parm1 - the Collection of instances to make transactional.

See Also:

the new Query

refresh

public void refresh(java.lang.Object parm1)

Description copied from interface: PersistenceManager

Refresh the state of the instance from the data store.

In an optimistic transaction, the state of instances in the cache might not match the state in the data store. This method is used to reload the state of the instance from the data store so that a subsequent commit is more likely to succeed.

Outside a transaction, this method will refresh nontransactional state.

Specified by:

refresh in interface PersistenceManager

Parameters:

parm1 - the instance to refresh.

refreshAll

public void refreshAll(java.util.Collection parm1)

Description copied from interface: PersistenceManager

Refresh the state of a Collection of instances from the data store.

Specified by:

refreshAll in interface PersistenceManager

Parameters:

parm1 - the Collection of instances to refresh.

See Also:

PersistenceManager.refresh(Object pc)

refreshAll

public void refreshAll(java.lang.Object[] parm1)

Description copied from interface: PersistenceManager

Refresh the state of an array of instances from the data store.

Specified by:

refreshAll in interface PersistenceManager

Parameters:

parm1 - the array of instances to refresh.

See Also:

PersistenceManager.refresh(Object pc)

refreshAll

public void refreshAll()

Description copied from interface: PersistenceManager

Refresh the state of all applicable instances from the data store.

If called with an active transaction, all transactional instances will be refreshed. If called outside an active transaction, all nontransactional instances will be refreshed.

Specified by:

refreshAll in interface PersistenceManager

See Also:

PersistenceManager.refresh(Object pc)

retrieve

public void retrieve(java.lang.Object iObject)

Description copied from interface: PersistenceManager
