NAME

       ColorData, GSData, MobilityData, MoveData, VoidData - Data subclasses for storing common undo information

SYNOPSIS

       #include <Unidraw/Commands/datas.h>

DESCRIPTION

       The  Unidraw  library predefines several Data subclasses for storing common undo information: ColorData stores two PSColors (usually repre-
       senting foreground and background colors), while GSData stores a complete set of graphics state	in  a  FullGraphic  object.   MobilityData
       stores the mobility and graphics state information needed to undo a change in mobility. MoveData stores a horizontal and vertical distance.
       VoidData stores a void pointer as a useful alternative to deriving trivially from Data just to store one word of information.

COLORDATA PUBLIC OPERATIONS

       ColorData(PSColor*, PSColor*)
	      Create a ColorData instance, supplying the PSColor objects it stores.

GSDATA PUBLIC OPERATIONS

       GSData(Graphic*)
	      Create a GSData instance, supplying the Graphic object from which to copy a complete set of graphics state.  The GSData  constructor
	      copies this information into its _gs member, from whence it can be retrieved later.

MOBILITYDATA PUBLIC OPERATIONS

       MobilityData(Mobility, Graphic*)
	      Create  a  MobilityData  instance,  supplying the mobility and a Graphic object from which to copy a complete set of graphics state.
	      The MobilityData constructor copies the graphic into its _gs member, from whence it can be retrieved later.

MOVEDATA PUBLIC OPERATIONS

       MoveData(float, float)
	      Create a MoveData instance, supplying two floating point numbers that normally represent horizontal and vertical movement.

VOIDDATA PUBLIC OPERATIONS

       VoidData(void*)
	      Create a VoidData instance, supplying a pointer to an object of unknown type.
