Detailed Description

This class is the base class for persistent reactors, which notify top-level objects about modification events. To implement your own notification mechanism, re-implement the recvPropagateModify() and xmitPropagateModify() methods of the base class.

Member Function Documentation

◆ recvPropagateModify()

virtual void OdTfPersistentReactor::recvPropagateModify ( const OdTfObject * pSubElm )

pure virtual

Allows a sub-element of a complex element to notify its parent element that it has been changed.

Parameters

pSubElm [in] A pointer to the modified sub-element.

Remarks: The notification algorithm works the following way:

The call of the method close() of the sub-element object triggers a modification notification handler, which calls the xmitPropagateModify() method.

The sub-element object calls the recvPropagateModify() method of its parent element and passes to it the pointer to itself.

The method recvPropagateModify() of the parent element sends a modification notification to the top element of its class hierarchy.

The default implementation of this function does nothing. 
This function can be overridden in custom classes.

◆ xmitPropagateModify()

virtual void OdTfPersistentReactor::xmitPropagateModify ( ) const

pure virtual

Allows a sub-element of a complex element to notify its root element that it has been changed.

Remarks: The default implementation of the function informs the database that contains the owner object about modifications and also attaches triggering reactor objects to the database. This function can be overridden in custom classes.

The documentation for this class was generated from the following file:
