Direct Known Subclasses:

TLcdSLDGXYPainterFactory

public abstract class ALcdSLDGXYPainterFactory
extends Object

Factory to create painters for feature type styles, rules and symbolizers. A feature type style is the top level element of an SLD for which painters need to be created. The feature type styles contains a set of rules which in turn contain symbolizers. For each of these elements, a factory method is defined. There is a factory method per level, to allow changing just the implementation at a level, without losing the capability to take advantage of the implementations at the other levels.

Depending on the actual implementation of the factory methods, low level factory methods may be called by the higher level factory methods.
