public abstract class Translator

extends java.lang.Object

A translator is parses a resource containing JSP syntax into XML, translates the XML with a stylesheet and compiles the output. It also handles all dependency checking. Currently we support two types of output generation, servlets and tag handlers. Subclasses need to implement the following methods:

• getStyleSheet - specifies the translator that will generate output
