Documentation for Class Dictionary in 3rd Use Case

Class Dictionary Graph for CD

Class Dictionary Graph for CDG

I. Textual Class Dictionary with Grammars and Input Files.

• cd.cd
• AltEdge-input
• AltVert-input
• ConstEdge-input
• ConstVert-input
• Demeter-input

II. Modification to UseCase2

I.  Added some default edges that connect Graph to Vertex or Edge;
II. Added new classes for constructing and printing a CDG.

III. Design Patterns Used in 2nd Use Case

   Adapter       -- Convert the interface of a class into anther
		    interface clients expect, lets classes work together
		    that couldn't otherwise because of incompatible
		    interfaces.

	Example:  Edge :   AltEdge | ConstEdge
        		*common*
          		"from"     < from > Vertex
               		[ "Bendpoints" < middlepoints > Coordinates ] 
          		"to"    < to > Vertex .



		     		  // ConstEdge is the subclass of Edge
		  ConstEdge = "ConstEdge"
            		< edgename > EdgeName .
				  // Adapt the Edge's interface to EdgeName
				     by some PPs, such as cppDrawEdges

   Facade        -- Provide a unified interface to aa set of interfaces
		    in a subsystem, defines a higher level interface that
		    makes the subsystem easier to use. 

	Example: 	 // 6 different subsystems

			(1)Graph = <edges>   Edge_List
				   <vertices> Vertex_List.
				   [<defaultConstVertex> ConstVertex]
	   			   [< defaultAltVertex> AltVertex]
	                           [<defaultConstEdge> ConstEdge]
	                           [<defaultAltEdge> AltEdge].

				   
			(2)ConstEdge = <edgename> EdgeName.				       

			(3)EdgeName = <name> DemIdent
				      <e_position> Coordinates.
			(4)Coordinates = <coords> DemString.

			(5)VertexName = <name> DemIdent
					[<vn_position> Coordinates]

			(6)Cd_Graph = <adjacencies> Cd_Adj_List.

   Interpreter    -- Given a language, define a represention for 
		     its grammar along with an interpreter that uses the 
		     representation to interpret sentences in the language.

	Example:      the  cd.cd provided by pp group

   Iterator      -- Provide a way to access the elements of an 
		    aggregate object sequentially without exposing its 
		    underlying representation.
	
	Example:      
		      //list of edges
		   Edge_List ~ Edge { Edge }.
		    
		      //list of vertices
		   Vertex_List ~ Vertex { Vertex }.
		
		      // List of Cd_Adjacency
		   Cd_Adj_List ~ { Cd_Adjacency }. 

		      //List of Cd_LVertex
		   Cd_LV_List ~ { Cd_LVertex }. 
		
		      //List of Cd_Vertex
		   Cd_V_BarList ~ Cd_Vertex { Cd_Vertex }.
