struct SelectionDAG::DAGNodeDeletedListener

Declaration

struct SelectionDAG::DAGNodeDeletedListener : public DAGUpdateListener { /* full declaration omitted */ };

Description

Clients of various APIs that cause global effects on the DAG can optionally implement this interface. This allows the clients to handle the various sorts of updates that happen. A DAGUpdateListener automatically registers itself with DAG when it is constructed, and removes itself when destroyed in RAII fashion.
