Class AbstractReadHandlerFactory

java.lang.Object
  org.pentaho.reporting.libraries.xmlns.parser.AbstractReadHandlerFactory

public abstract class AbstractReadHandlerFactory
extends java.lang.Object

The AbstractReadHandlerFactory provides a base implementation for all read-handler factories. A read-handler factory decouples the tag-handlers of a SAX parser and allows to configure alternate parser configuations at runtime, resulting in a more flexible parsing process.
