Class TransformerObjectSupport

java.lang.Object
  org.springframework.xml.transform.TransformerObjectSupport

Direct Known Subclasses:

AbstractXPathTemplate

public abstract class TransformerObjectSupport
extends java.lang.Object

Convenient base class for objects that use a Transformer. Subclasses can call createTransformer() or transform(Source, Result). This should be done per thread (i.e. per incoming request), because Transformer instances are not thread-safe.

1.0.0
