Method Detail

iterator

public java.util.Iterator iterator()

Description copied from interface: Extent

Returns an iterator over all the instances in the Extent. The behavior of the returned iterator might depend on the setting of the ignoreCache flag in the owning PersistenceManager.

Specified by:

iterator in interface Extent

Returns:

an iterator over all instances in the Extent

hasSubclasses

public boolean hasSubclasses()

Description copied from interface: Extent

Returns whether this Extent was defined to contain subclasses.

Specified by:

hasSubclasses in interface Extent

Returns:

true if this Extent was defined to contain instances that are of a subclass type.

getCandidateClass

public java.lang.Class getCandidateClass()

Description copied from interface: Extent

An Extent contains all instances of a particular class in the data store; this method returns the Class of the instances.

Specified by:

getCandidateClass in interface Extent

Returns:

the Class of instances of this Extent.

getPersistenceManager

public PersistenceManager getPersistenceManager()

Description copied from interface: Extent

An Extent is managed by a PersistenceManager; this method gives access to the owning PersistenceManager.

Specified by:

getPersistenceManager in interface Extent

Returns:

the owning PersistenceManager

closeAll

public void closeAll()

Description copied from interface: Extent

Close all Iterators associated with this Extent instance. Iterators closed by this method will return false to hasNext() and will throw NoSuchElementException on next(). The Extent instance can still be used as a parameter of Query.setExtent, and to get an Iterator.

Specified by:

closeAll in interface Extent

close

public void close(java.util.Iterator p0)

Description copied from interface: Extent

Close an Iterator associated with this Extent instance. Iterators closed by this method will return false to hasNext() and will throw NoSuchElementException on next(). The Extent instance can still be used as a parameter of Query.setExtent, and to get an Iterator.

Specified by:

close in interface Extent

Parameters:

p0 - an Iterator obtained by the method iterator() on this Extent instance.
