Description

Obtains the pointer to an optional input shape range based on the input index in the operator prototype definition.

Prototype

const Range<Shape> *GetOptionalInputShapeRange(const size_t ir_index) const

Parameters

Returns

Pointer to the shape range. If ir_index is invalid or the input is not instantiated, a null pointer is returned.

Restrictions

None

Example

const auto infer_shape_range_func = [](gert::InferShapeRangeContext *context) -> graphStatus {
  auto input_shape_range = context->GetOptionalInputShapeRange(0U);
  auto output_shape_range = context->GetOutputShapeRange(0U);
  output_shape_range->SetMin(const_cast<gert::Shape *>(input_shape_range->GetMin()));
  output_shape_range->SetMax(const_cast<gert::Shape *>(input_shape_range->GetMax()));
  return GRAPH_SUCCESS;
};
