Direct Known Subclasses:

ParserFactorySupport, Preprocessor

public abstract class ProcessorSupport
extends Object

A base class for configuration processors. The class provides support for traversing a tree of stream configuration components and generates a "stack trace" if any overridden method throws a BeanIOConfigurationException.

Since:

2.0
