Member Function Documentation

◆ GetSlavePtr()

istd::IChangeable * istd::CChangeDelegator::GetSlavePtr ( ) const

inlinevirtual

Sets the slave object pointer.

Its IChangeable methods will be called, if this object is updated.

Implements istd::IChangeDelegator.

Definition at line 51 of file CChangeDelegator.h.

◆ OnBeginChanges()

virtual void istd::CChangeDelegator::OnBeginChanges ( )

virtual

Callback function for begin change event.

Please note, that in some cases no following OnEndChanges can be called.

Reimplemented from istd::IChangeable.

Reimplemented in istd::TChangeDelegator< Base >, istd::TChangeDelegator< ibase::IHierarchicalCommand >, and istd::TChangeDelegator< IHierarchicalMessageContainer >.

◆ OnEndChanges()

virtual void istd::CChangeDelegator::OnEndChanges ( const ChangeSet & changeSet )

virtual

Callback function for end change event.

Reimplemented from istd::IChangeable.

Reimplemented in istd::TChangeDelegator< Base >, istd::TChangeDelegator< ibase::IHierarchicalCommand >, and istd::TChangeDelegator< IHierarchicalMessageContainer >.

◆ SetSlavePtr()

void istd::CChangeDelegator::SetSlavePtr ( istd::IChangeable * slavePtr )

inlinevirtual

Gets the slave object pointer.
