Member Function Documentation

Accept()

void Accept ( ILayerVisitor &  visitor ) const

overridevirtual

Implements IConnectableLayer.

Definition at line 33 of file SubtractionLayer.cpp.

References Layer::GetName(), and ILayerVisitor::VisitSubtractionLayer().

Clone()

SubtractionLayer * Clone ( Graph &  graph ) const

overridevirtual

Creates a dynamically-allocated copy of this layer.

Parameters

[in]

graph

overridevirtual

Makes a workload for the Subtraction type.

Parameters

[in]	graph	The graph where this layer can be found.
[in]	factory	The workload factory which will create the workload.

Returns

A pointer to the created workload, or nullptr if not created.

Implements Layer.
