Identify and Implement Syntactic and Semantic Observers Design Patterns. (A02.T01)

[mayanje]

Purpose

The purpose here is to implement Syntactical node creation listeners, and Parser build action dispatchers, so that Syntax directed strategies can be used, applied and elaborated.

ProgramClassBuilderNodeListener class

This class is a NodeListener instance over a IProgramClassBuilder interface imlplementation, witch is able to listen to Systactical nodes creation and parsing action performing.

ProgramClassBuilderNodeDispatcher class

This class is a NodeDispatcher instance over a IProgramClassBuilder interface imlplementation, witch is able to dispatch Syntactical nodes created and parsing actions performed, to registered NodeListener instances and ProgramClassBuilderNodeListener instances.

Other classes descriptions

Class	Description
NodeListener	An interface that describes the contract of any objet able to listen to Syntactical node creation.
IProgramClassBuilder	An interface that describes the contract of any objet able to handle parsing actions for program class builing.
NodeDispatcher	It is the base class of any object which can dispatch node creation actions to registered NodeListener instances.
