public interface StyleVisitor
An interface for classes that want to perform operations on a Style hierarchy. It forms part of a GoF Visitor Pattern implementation. A call to style.accept(StyleVisitor) will result in a call to one of the methods in this interface. The responsibility for traversing sub filters is intended to lie with the visitor (this is unusual, but permitted under the Visitor pattern). A typical use would be to transcribe a style into a specific format, e.g. XML or SQL. Alternatively it may be to extract specific information from the Style structure, for example a list of all fills.
