A base class for Op implementations that are backed by a single Operation.

Each operation registered in the TensorFlow core is provided as a RawOp. Custom operations working with only a single operation may also derive from this class.

Public Methods

final boolean	equals(Object obj)
final int	hashCode()
Operation	op() Return this unit of computation as a single Operation.
final String	toString()

Inherited Methods

From class java.lang.Object

From interface org.tensorflow.op.Op

abstract ExecutionEnvironment	env() Return the execution environment this op was created in.
abstract Operation	op() Return this unit of computation as a single Operation.

Public Methods

public final boolean equals (Object obj)

public final int hashCode ()

public Operation op ()

Return this unit of computation as a single Operation.

For a raw op, the returned value correspond to the TensorFlow operation wrapped by this op.

For a composite op, the returned value usually correspond to the last operation invoked in a chain or to a NoOp grouping one or more operations as a single unit of computation.
