Examples of sun.java2d.loops.SurfaceType

sun.java2d.loops.SurfaceType
A SurfaceType object provides a chained description of a type of drawing surface. The object will provide a single String constant descriptor which is one way of viewing or accessing a particular drawing surface as well as a pointer to another SurfaceType which describes the same drawing surface in a different (typically more generalized) way.
A more specific description of a surface is considered a "subtype" and a more general description is considered a "supertype". Thus, the deriveSubType method provides a way to create a new SurfaceType that is related to but more specific than an existing SurfaceType and the getSuperType method provides a way to ask a given SurfaceType for a more general way to describe the same surface.
Note that you cannot construct a brand new root for a chain since the constructor is private. Every chain of types must at some point derive from the Any node provided here using the deriveSubType() method. The presence of this common Any node on every chain ensures that all chains end with the DESC_ANY descriptor so that a suitable General GraphicsPrimitive object can be obtained for the indicated surface if all of the more specific searches fail.
