Method Detail

streamContent

public void streamContent(CopletInstanceData coplet,
                          String uri,
                          ContentHandler contentHandler)
                   throws SAXException

Overrides:

streamContent in class CachingURICopletAdapter

Throws:

SAXException

See Also:

URICopletAdapter.streamContent(org.apache.cocoon.portal.coplet.CopletInstanceData, java.lang.String, org.xml.sax.ContentHandler)

handleCopletInstanceEvent

public void handleCopletInstanceEvent(CopletInstanceEvent e)

This adapter listens for CopletLinkEvents. If it catches one the link uri is saved in the coplet instance data for further handling in the ProxyTransformer. There is a special CopletLinkEvent with the uri "createNewCopletInstance", which is the trigger to create a new instance of the one that is the target of the event.

Overrides:

handleCopletInstanceEvent in class CachingURICopletAdapter

renderErrorContent

protected boolean renderErrorContent(CopletInstanceData coplet,
                                     ContentHandler handler)
                              throws SAXException

Render the error content for a coplet

Parameters:

coplet -

handler -

Returns:

True if the error content has been rendered, otherwise false

Throws:

SAXException
