package HLRTest 

	---Purpose: This package   is  a test  of  the    Hidden Lines
	--          algorithms instantiated on the BRep Data Structure
	--          and using the Draw package to display the results.

    class Projector;
	---Purpose: Draw Variable Projector to test
	
    class OutLiner;
	---Purpose: Draw Variable Outliner to test

    Set(Name : CString;

	---Purpose: Set a Projector Variable

    GetProjector(Name : in out CString;
                 P :    in out Projector from HLRAlgo) 
    returns Boolean; 
	---Purpose: Get a projector variable
	--          Returns false if the variable is not a projector

	---Purpose: Set a OutLiner Variable

    GetOutLiner(Name : in out CString)  
    	returns OutLiner from HLRTopoBRep;
	---Purpose: Get a outliner variable
	--          Returns a null handle if the variable is not a outliner
