Method Details

createCopy

protected ExecutionOperator createCopy()

Overrides:

createCopy in class OperatorBase

getSupportedInputChannels

public List<ChannelDescriptor> getSupportedInputChannels(int index)

Description copied from interface: ExecutionOperator

Display the supported Channels for a certain InputSlot.

Specified by:

getSupportedInputChannels in interface ExecutionOperator

Parameters:

index - the index of the InputSlot

Returns:

an List of Channels' Classes, ordered by their preference of use

getSupportedOutputChannels

public List<ChannelDescriptor> getSupportedOutputChannels(int index)

Description copied from interface: ExecutionOperator

Display the supported Channels for a certain OutputSlot.

Specified by:

getSupportedOutputChannels in interface ExecutionOperator

Parameters:

index - the index of the OutputSlot

Returns:

an List of Channels' Classes, ordered by their preference of use

evaluate

public Tuple<Collection<ExecutionLineageNode>,Collection<ChannelInstance>> evaluate(ChannelInstance[] inputs,
 ChannelInstance[] outputs,
 TensorflowExecutor tensorflowExecutor,
 OptimizationContext.OperatorContext operatorContext)

Description copied from interface: TensorflowExecutionOperator

Evaluates this operator. Takes a set of inputs and produces a set of outputs.

In addition, this method should give feedback of what this instance was doing by wiring the LazyExecutionLineageNodes of input and ouput ChannelInstances and providing a Collection of executed OptimizationContext.OperatorContexts.

Specified by:

evaluate in interface TensorflowExecutionOperator

Parameters:

inputs - ChannelInstances that satisfy the inputs of this operator

outputs - ChannelInstances that collect the outputs of this operator

operatorContext - OptimizationContext.OperatorContext of this instance

Returns:

Collections of what has been executed and produced
