java.lang.Object

All Implemented Interfaces:

Transformer

public class CachedFOPTransformer

extends AbstractXSLTransformer

implements Transformer

This class defines the implementation of a FOP transformer using the Transformation API for XML (TRaX). All templates (compiled XSL templates) are cached upon first use. To reload the cache, reload the application.

This Transformer uses the property "outputType" to determine what type of output to produce. Supported values are "pdf" and "svg".
