package ShapeProcess 

    	---Purpose: Shape Processing module
	-- allows to define and apply general Shape Processing as a
	-- customizable sequence of Shape Healing operators. The
	-- customization is implemented via user-editable resource
	-- file which defines sequence of operators to be executed
	-- and their parameters.

is

    class Context; 
    	---Purpose: Provides general context for processing (resource file)
    	class ShapeContext;
	    ---Purpose: Extends context to support processing of the shape

    deferred class Operator;
    	---Purpose: Defines interface to Operator which do the job
	primitive OperFunc;
	class UOperator;
	    ---Purpose: Customizable operator-container loaded by OperFunc

    class OperLibrary;
    	---Purpose: Provides standard set of operators

    class DictionaryOfOperator instantiates 
    	  Dictionary from Dico (Operator from ShapeProcess);

    RegisterOperator (name: CString; op: Operator from ShapeProcess)
    returns Boolean;
    	---Purpose: Registers operator to make it visible for Performer

    FindOperator (name: CString; op: out Operator from ShapeProcess)
    returns Boolean;
    	---Purpose: Finds operator by its name

    Perform (context: Context from ShapeProcess; seq: CString) 
    returns Boolean;
    	---Purpose: Performs a specified sequence of operators on Context
	--          Resource file and other data should be already loaded
	--          to Context (including description of sequence seq)
