Detailed Description

template<class T>
class d_Ref_NoTx< T >

Expresses relationships to objects.

This class works such as d_Ref but manages no transactional objects.

LOCATION: d_Ref_NoTx.h

Usage: d_Ref_NoTx< <linked-class> > <property-name>;

WHERE:

<linked-class>: Name of class to link. Can be only a persistent class (inherited from d_Object)

<property-name>: name of property

EXAMPLES:

* Reference to Invoice object d_Ref_NoTx<Invoice> myInvoice;

SEE ALSO: d_Ref, d_Object

ODMG: Extension

Constructor & Destructor Documentation

template<class T> d_Ref_NoTx< T >::d_Ref_NoTx (    )

Default constructor. Creates a null reference.

template<class T> d_Ref_NoTx< T >::d_Ref_NoTx (  const T *    iObject )

Creates a reference to object.

template<class T> d_Ref_NoTx< T >::d_Ref_NoTx (  const d_Ref_NoTx< T > &    iRef )

Copy constructor. Copy the reference of .

template<class T> d_Ref_NoTx< T >::d_Ref_NoTx (  const d_Ref< T > &    iRef )

Creates a reference by the d_Ref object .

template<class T> d_Ref_NoTx< T >::d_Ref_NoTx (  const d_Ref_Any &    iRef )

Creates a reference by the d_Ref_Any object .

Member Function Documentation

template<class T> T& d_Ref_NoTx< T >::operator * (    )

Returns the persistent object in memory. If the object is not present in memory Orient ODBMS loads the object from storage to memory trasparently. If the reference is null then an exception d_Error_RefNull or d_Error_RefInvalid is raised. SEE ALSO: operator ->(), ptr()

template<class T> T* d_Ref_NoTx< T >::operator-> (    )

Returns the persistent object in memory. If the object is not present in memory Orient ODBMS loads the object from database to memory trasparently. If the reference is null then an exception d_Error_RefNull or d_Error_RefInvalid is raised. This operator permits to handle d_Ref<> as common C++ pointer. SEE ALSO: operator *(), ptr()

template<class T> d_Ref_NoTx<T>& d_Ref_NoTx< T >::operator= (  const T *    iSource )

Set the reference to object.

template<class T> T* d_Ref_NoTx< T >::ptr (    )

Returns the persistent object in memory. If the object is not present in memory Orient ODBMS loads the object from storage to memory trasparently. If the reference is null then an exception d_Error_RefInvalid is raised. SEE ALSO: operator ->(), operator *()
