A builder for Operations.
For example, the following uses the builder to create an operation that produces the constant "3" as its output:
// env is an ExecutionEnvironment, such as a Graph instance.
try (Tensor c1 = Tensor.create(3.0f)) {
env.opBuilder("Const", "MyConst")
.setAttr("dtype", c1.dataType())
.setAttr("value", c1)
.build();

Public Methods
public abstract OperationBuilder addControlInput (Operation control)
Ensure that the operation does not execute before the control operation does.
A control input is an Operation that must be executed before running the operation currently being built.
For example, an Assert operation may be added as a control input for this operation. The Assert now behaves as a pre-condition that will always verify itself before running the operation.
Parameters
| control | operation that must be executed before running this operation. |
|---|
Returns
- the OperationBuilder instance for chaining.
public abstract OperationBuilder addInput (Output<?> input)
Add the output of another operation as the next input of the operation being built.
Parameters
| input | Output supposed to be the input of the operation being built. |
|---|
Returns
- the OperationBuilder instance for chaining.
public abstract OperationBuilder addInputList (Output[]<?> inputs)
Add the outputs of another operation as the next inputs of the operation being built.
Parameters
| inputs | list of Output supposed to be the inputs of the operation being built. |
|---|
Returns
- the OperationBuilder instance for chaining.
public abstract Operation build ()
Build the Operation.
The following action will also be performed depending on the current execution environment.
- In eager mode, the result of the operation will be computed immediately.
- In graph mode, the operation will be added as a node to the graph to be executed later,
when running a
Session.
The OperationBuilder is not usable after build() returns.
