Class AbstractReader

java.lang.Object
  org.apache.avalon.framework.logger.AbstractLogEnabled
      org.apache.cocoon.reading.AbstractReader

All Implemented Interfaces:

Poolable, Recyclable, Component, LogEnabled, Reader, SitemapModelComponent, SitemapOutputComponent

Direct Known Subclasses:

CaptchaReader, ComposerReader, ResourceReader, ServiceableReader

public abstract class AbstractReader
extends AbstractLogEnabled
implements Reader, Recyclable

A reader can be used to generate binary output for a request. This abstract class helps in implementing a custom reader.
