Detailed Description

This layer represents an unknown operation in the input graph.

Definition at line 14 of file StandInLayer.hpp.

Constructor & Destructor Documentation

◆ StandInLayer()

StandInLayer	(	const StandInDescriptor &	param,
		const char *	name
	)

protected

Constructor to create a StandInLayer.

Parameters

[in]	param	StandInDescriptor to configure the stand-in operation.
[in]	name	Optional name for the layer.

Definition at line 12 of file StandInLayer.cpp.

References armnn::StandIn.

     : LayerWithParameters(param.m_NumInputs, param.m_NumOutputs, LayerType::StandIn, param, name)
 {
 }

◆ ~StandInLayer()

~StandInLayer ( )

protecteddefault

Default destructor.

Member Function Documentation

◆ Clone()

StandInLayer * Clone ( Graph & graph ) const

overridevirtual

Creates a dynamically-allocated copy of this layer.

Parameters

[in] graph The graph into which this layer is being cloned.

Implements Layer.

Definition at line 26 of file StandInLayer.cpp.

References Layer::GetName(), and LayerWithParameters< StandInDescriptor >::m_Param.

 {
     return CloneBase<StandInLayer>(graph, m_Param, GetName());
 }

◆ CreateWorkload()

std::unique_ptr< IWorkload > CreateWorkload ( const IWorkloadFactory & factory ) const

overridevirtual

Empty implementation explictly does NOT create a workload.

Throws Exception if called.

Parameters

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

Returns: Does not return anything. Throws Exception if called.

Implements Layer.

Definition at line 17 of file StandInLayer.cpp.

References armnn::IgnoreUnused().

 {
     IgnoreUnused(factory);
     // This throws in the event that it's called. We would expect that any backend that
     // "claims" to support the StandInLayer type would actually substitute it with a PrecompiledLayer
     // during graph optimization. There is no interface on the IWorkloadFactory to create a StandInWorkload.
     throw Exception("Stand in layer does not support creating workloads");
 }

◆ ExecuteStrategy()

void ExecuteStrategy ( IStrategy & strategy ) const

overridevirtual

Apply a visitor to this layer.

Reimplemented from Layer.

Definition at line 44 of file StandInLayer.cpp.

References IStrategy::ExecuteStrategy(), Layer::GetName(), and LayerWithParameters< StandInDescriptor >::GetParameters().

 {
     strategy.ExecuteStrategy(this, GetParameters(), {}, GetName());
 }

◆ InferOutputShapes()

std::vector< TensorShape > InferOutputShapes ( const std::vector< TensorShape > & inputShapes ) const

overridevirtual

Empty implementation that throws Exception if called.

otherwise infers the output shapes from given input shapes and layer properties.

Parameters

[in] inputShapes The input shapes layer has.

Returns: Does not return anything. Throws Exception if called.

Reimplemented from Layer.

Definition at line 31 of file StandInLayer.cpp.

References armnn::IgnoreUnused().

 {
     IgnoreUnused(inputShapes);
     throw Exception("Stand in layer does not support infering output shapes");
 }

◆ ValidateTensorShapesFromInputs()

void ValidateTensorShapesFromInputs ( )

overridevirtual

Check if the input tensor shape(s) Does nothing since cannot validate any properties of this layer.

Parameters

[in] shapeInferenceMethod Indicates if output shape shall be overwritten or just validated.

Implements Layer.

Definition at line 37 of file StandInLayer.cpp.

 {
 
     // Cannot validate this layer since no implementation details can be known by the framework
     // so do nothing here.
 }
