Method Detail

getFilterForRead

public INamespaceFilter getFilterForRead(INamespaceFilter nmspFilter,
                                         NamespaceFilterMode mode)
                                  throws WcmException

Returns a read filter object that should be applied to the resource list of the predecessor filter. If the manager decides not to apply a filter it must return the reference to the predecessor filter. It should not return null here, but instead throw an exception if something went wrong. Returning null or throwing an exception will stop the filtering process.

Parameters:

nmspFilter - The predecessor filter in the cascade

mode - The namespace filter mode that specifies for which operation the filter is called (getResource, getChildren, etc.)

Returns:

The filter object

Throws:
