OpenVINO Model Pass

ov::pass::ModelPass is used for transformations that take entire ov::Model as an input and process it.

Template for ModelPass transformation class

@snippet src/transformations/template_model_transformation.hpp model_pass:template_transformation_hpp

@snippet src/transformations/template_model_transformation.cpp model_pass:template_transformation_cpp

Using ov::pass::ModelPass, you need to override the run_on_model method where you will write the transformation code. Return value is true if the original model has changed during transformation (new operation was added, or operations replacement was made, or node attributes were changed); otherwise, it is false. Also ov::pass::ModelPass based transformations can be executed via ov::pass::Manager.
