Class DefaultMDEXStateManager

  com.endeca.portal.data.AbstractMDEXStateManager
      com.endeca.portal.data.DefaultMDEXStateManager

All Implemented Interfaces:

java.io.Serializable

public class DefaultMDEXStateManager
extends AbstractMDEXStateManager

This is a simple implementation of MDEXStateManager covering a very simple parent-child relationship of data sources. This model covers data sources with a single ancestor, and allows child data sources to add additional static functions to queries inherited from their ancestor. These static functions are whatever functions were configured in the data source's 'baseFunctions' property. "setting" a query on a data source with an ancestor results in actually setting the query on the ancestor, sans whatever static functions were initially configured on the child. This implementation can be useful for simplistic applications where either no relationships exist between MDEXStates or where they are only used to, for example, put RecordType filters (or some other static record filter) on different pages/tabs that otherwise share the same query state.

handleStateMerge

public QueryState handleStateMerge(javax.portlet.PortletRequest request,
                                   MDEXState mdexState)
                            throws QueryStateException

Description copied from class: AbstractMDEXStateManager

Handle query-time determination of the query a portlet should fire before the portlet requests execution

Specified by:

handleStateMerge in class AbstractMDEXStateManager

Returns:

the portlet-visible QueryState as determined by the request and mdexState

Throws:

QueryStateException

handleStateUpdate

public void handleStateUpdate(javax.portlet.PortletRequest request,
                              MDEXState mdexState,
                              QueryState newQueryState)
                       throws QueryStateException

Description copied from class: AbstractMDEXStateManager

Encapsulate data source update logic. This method will be called any time a DataSource's QueryState is updated.

Specified by:

handleStateUpdate in class AbstractMDEXStateManager

Throws:

QueryStateException
