org.apache.stanbol.commons.solr.web.dispatch.DelegatingSolrDispatchFilter

All Implemented Interfaces:

javax.servlet.Filter

Direct Known Subclasses:

public abstract class DelegatingSolrDispatchFilter
extends org.apache.solr.servlet.SolrDispatchFilter

A SolrDispatchFilter that does not create a new CoreContainer on initialisation, but instead delegates to a already existing instance.

Users of this Class MUST implement two methods

• getCoreContainer(): Called during Filter.init(javax.servlet.FilterConfig) to get the CoreContainer instance to be used for the Servlet filter.
• ungetCoreContainer(): Called during the Filter.destroy() method to indicate the the delegate is no longer needed by this Filter ServiceReference provided by #getCoreContainerReference()
