Class ChannelRenderingBuffer

java.lang.Object
  org.jasig.portal.utils.SAX2FilterImpl
      org.jasig.portal.utils.SAX2BufferImpl
          org.jasig.portal.ChannelRenderingBuffer

All Implemented Interfaces:

ContentHandler, DTDHandler, EntityResolver, ErrorHandler, LexicalHandler, XMLFilter, XMLReader

Deprecated. IChannel rendering code will be replaced with portlet specific rendering code in a future release

@Deprecated
public class ChannelRenderingBuffer
extends SAX2BufferImpl

Channel Rendering buffer allows portal to accumulate a list of all channels that will have to be rendered. This is done by accumulating layout content (full page content minus content provided by the channels). The entire document is accumulated in a buffer. Information about channel elements is passed to a ChannelManager. Once the end of the document is reached, the entire buffer is released to a provided Document Handler.
