All Implemented Interfaces:

SearchPolicy

public class SelfContainedSearchPolicy
extends java.lang.Object

setModuleManager

public void setModuleManager(ModuleManager mgr)
                      throws java.lang.IllegalStateException

This method is part of the SearchPolicy interface. This method is called by the ModuleManager once to give the search policy instance a reference to its associated module manager. This method should be implemented such that it cannot be called twice; calling this method a second time should produce an illegal state exception.

Specified by:

setModuleManager in interface SearchPolicy

Parameters:

mgr - the module manager associated with this search policy.

Throws:

java.lang.IllegalStateException - if the method is called more than once.
