tflite::OpResolver

This is an abstract class.

#include <op_resolver.h>

Abstract interface that returns TfLiteRegistrations given op codes or custom op names.

Summary

This is the mechanism that ops being referenced in the flatbuffer model are mapped to executable function pointers (TfLiteRegistrations).

The lifetime of the TfLiteRegistration object whose address is returned by FindOp must exceed the lifetime of any InterpreterBuilder or Interpreter created with this OpResolver. Likewise the lifetime of the TfLiteRegistrationExternal object referenced from the TfLiteRegistration object, if any, must exceed the lifetime of any InterpreterBuilder or Interpreter created with this OpResolver.
