Class GraphOperation

java.lang.Object

org.tensorflow.GraphOperation

All Implemented Interfaces:

Operation

public final class GraphOperation
extends Object

Implementation for an Operation added as a node to a Graph.

GraphOperation instances are valid only as long as the Graph they are a part of is valid. Thus, if Graph.close() has been invoked, then methods on the GraphOperation instance may fail with an IllegalStateException.

GraphOperation instances are immutable and thread-safe.

Method Detail

name

public String name()

Description copied from interface: Operation

Returns the full name of the Operation.

type

public String type()

Description copied from interface: Operation

Returns the type of the operation, i.e., the name of the computation performed by the operation.

numOutputs

public int numOutputs()

Description copied from interface: Operation

Returns the number of tensors produced by this operation.

outputListLength

public int outputListLength(String name)

Description copied from interface: Operation

Returns the size of the list of Tensors produced by this operation.

An Operation has multiple named outputs, each of which produces either a single tensor or a list of tensors. This method returns the size of the list of tensors for a specific named output of the operation.

Parameters:

name - identifier of the list of tensors (of which there may be many) produced by this operation.

Returns:

the size of the list of Tensors produced by this named output.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

inputListLength

public int inputListLength(String name)

Description copied from interface: Operation

Returns the size of the given inputs list of Tensors for this operation.

An Operation has multiple named inputs, each of which contains either a single tensor or a list of tensors. This method returns the size of the list of tensors for a specific named input of the operation.

Parameters:

name - identifier of the list of tensors (of which there may be many) inputs to this operation.

Returns:

the size of the list of Tensors produced by this named input.

outputList

public Output<?>[] outputList(int idx,
                              int length)

Description copied from interface: Operation

Returns symbolic handles to a list of tensors produced by this operation.

Specified by:

outputList in interface Operation

Parameters:

idx - index of the first tensor of the list

length - number of tensors in the list

Returns:

array of Output

output

public <T> Output<T> output(int idx)

Description copied from interface: Operation

Returns a symbolic handle to one of the tensors produced by this operation.

Warning: Does not check that the type of the tensor matches T. It is recommended to call this method with an explicit type parameter rather than letting it be inferred, e.g. operation.<Integer>output(0)

Specified by:

output in interface Operation

Type Parameters:

T - The expected element type of the tensors produced by this output.

Parameters:

idx - The index of the output among the outputs produced by this operation.

toString

public String toString()

Overrides:

toString in class Object
