Constructor & Destructor Documentation

◆ ReshapeLayer()

ReshapeLayer	(	const ReshapeDescriptor &	desc,
		const char *	name
	)

protected

Constructor to create a ReshapeLayer.

Parameters

[in]	param	ReshapeDescriptor to configure the reshape operation.
[in]	name	Optional name for the layer.

Definition at line 16 of file ReshapeLayer.cpp.

References armnn::Reshape.

     : LayerWithParameters(1, 1, LayerType::Reshape, param, name)
 {
 }

◆ ~ReshapeLayer()

~ReshapeLayer ( )

protecteddefault

Default destructor.

Referenced by ReshapeLayer::IsEqual().

Member Function Documentation

◆ Accept()

void Accept ( ILayerVisitor & visitor ) const

overridevirtual

Implements IConnectableLayer.

Definition at line 52 of file ReshapeLayer.cpp.

References Layer::GetName(), LayerWithParameters< ReshapeDescriptor >::GetParameters(), and ILayerVisitor::VisitReshapeLayer().

Referenced by ReshapeLayer::IsEqual().

 {
     visitor.VisitReshapeLayer(this, GetParameters(), GetName());
 }

◆ Clone()

ReshapeLayer * 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 27 of file ReshapeLayer.cpp.

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

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

◆ CreateWorkload()

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

overridevirtual

Makes a workload for the Reshape 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.

 }

◆ InferOutputShapes()

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

overridevirtual

By default returns inputShapes if the number of inputs are equal to number of outputs, otherwise infers the output shapes from given input shapes and layer properties.

Parameters

[in] inputShapes The input shapes layer has.

Returns: A vector to the inferred output shape.

 }

◆ IsEqual()

bool IsEqual ( const Layer & other ) const

inline

Indicates if the other layer received is equal to this one.

Parameters

other The other layer to be compared with.

Returns: true if other layer is equal to this false otherwise.

◆ ValidateTensorShapesFromInputs()

void ValidateTensorShapesFromInputs ( )

overridevirtual

Check if the input tensor shape(s) will lead to a valid configuration of ReshapeLayer.
