Detailed Description

Abstract Base class for all mixed Graph Listener.

This is the virtual base class for mixed graphs meta-listener.

A MixedGraphListener will have to implement following pure methods :

• void whenNodeAdded( const void * ,gum::NodeId )
• void whenNodeDeleted( const void *,gum::NodeId )
• void whenArcAdded( const void *,gum::NodeId,gum::NodeId )
• void whenArcDeleted( const void *,gum::NodeId,gum::NodeId )
• void whenEdgeAdded( const void *,gum::NodeId,gum::NodeId )
• void whenEdgeDeleted( const void *,gum::NodeId,gum::NodeId )

Constructor & Destructor Documentation

MixedGraphListener() [1/2]

gum::MixedGraphListener::MixedGraphListener

(

MixedGraph *

g

)

default constructor

Parameters

g	the graph to listen to

Warning

Note that, by the aGrUM's constructor parameter's rule, the fact that g is passed as a pointer means that g is not copied, but only referenced by the listener.

Definition at line 47 of file mixedGraphListener.cpp.
