Known Indirect Subclasses
|
Performs computation on Tensors.
An Operation takes zero or more Tensors (produced by other Operations) as input, and
produces zero or more Tensors as output.
Public Methods
|
abstract
int
|
inputListLength(String name)
Returns the size of the given inputs list of Tensors for this operation.
|
|
abstract
String
|
name()
Returns the full name of the Operation.
|
|
abstract
int
|
numOutputs()
Returns the number of tensors produced by this operation.
|
|
abstract
<T>
Output<T>
|
output(int idx)
Returns a symbolic handle to one of the tensors produced by this operation.
|
|
abstract
Output[]<?>
|
outputList(int idx, int length)
Returns symbolic handles to a list of tensors produced by this operation.
|
|

|
outputListLength(String name)
Returns the size of the list of Tensors produced by this operation.
|
|
abstract
String
|
type()
Returns the type of the operation, i.e., the name of the computation performed by the
operation.
|
Public Methods
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.
Throws
| IllegalArgumentException |
if this operation has no input with the provided name.
|
public
abstract
String
name
()
Returns the full name of the Operation.
public
abstract
int
numOutputs
()
Returns the number of tensors produced by this operation.
public
abstract
Output<T>
output
(int idx)
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)
Parameters
| idx |
The index of the output among the outputs produced by this operation.
|
public
abstract
Output[]<?>
outputList
(int idx, int length)
Returns symbolic handles to a list of tensors produced by this operation.
Parameters
| idx |
index of the first tensor of the list |
| length |
number of tensors in the list |
public
abstract
int
outputListLength
(String name)
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.
Throws
| IllegalArgumentException |
if this operation has no output with the provided name.

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