Detailed Description

Make a value visible to user.

Note

TFPush is a virtual node that does not corresponds to real TensorFlow node Why this node is introduced:

• Any TensorFlow Nodes can be an output.
• So let any TFNode type can provide OutputIndex using Annotation.
• Problem comes when in transformation, output node can be replaced.
• This causes that OutputIndex Annotation should be copied to new node.
• This makes every transformation in any Dialect code change.
• And even worse, this makes every new transformation follow this rule.
• Which is not good.
• Thus, like loco Canonical does, follow loco::Push.

index() [2/2]

const

Get associated output index.

The behavior of this method is undefined when "index" is not set before.

NOTE This method intentionally returns "GraphOutputIndex" instead of "const GraphOutputIndex &" not to expose the internal implementation details.

Definition at line 114 of file TFNode.cpp.

  assert(_index >= std::numeric_limits<loco::GraphOutputIndex>::min());
  assert(_index <= std::numeric_limits<loco::GraphOutputIndex>::max());

index_reset()

void moco::TFPush::index_reset ( void  )

inline

Reset output index.

Definition at line 73 of file TFPush.h.

{ _index = -1; }

indexed()

bool moco::TFPush::indexed ( void  ) const

inline

Check whether index is initialized.

NOTE "indexed" method does not validate whether index is in a valid range
