oracle.jbo.mom
Class DefinitionContextAgeable

java.lang.Object
oracle.jbo.mom.DefinitionContext
oracle.jbo.mom.DefinitionContextStandard
oracle.jbo.mom.DefinitionContextAgeable

All Implemented Interfaces:

DefinitionMgrListener

public class DefinitionContextAgeable

extends DefinitionContextStandard

implements DefinitionMgrListener

This class provides an implementation of the abstract DefinitionContext class in which the MOM cache supports ageing.

In this class (as in its superclass), no state is shared between the MOM cache and MOM parser functionality, and the latter is delegated to a MOMParser provided to the constructor. (The client can choose MDS vs non-MDS versions of the MOMParser).

Method Detail

retireLeastRecentlyUsed

public void retireLeastRecentlyUsed(int numToRetire)

Description copied from class: DefinitionContext

Retires the specified number of least recently used non-retired ageable metaobjects in the MOM cache. If the MOM cache contains fewer non-retired ageable metaobjects than the specified number, then all ageable metaobjects will be retired. This method is a no-op in a subclass which does not support ageing.

Overrides:

retireLeastRecentlyUsed in class DefinitionContext

objectUseUpdated

public void objectUseUpdated(DefinitionManager manager,
                             DefinitionContext defCtx,

                             DefinitionObjectInfo defObjInfo)

Specified by:

objectUseUpdated in interface DefinitionMgrListener

dumpDefObjInfo

public void dumpDefObjInfo(DefinitionManager manager,
                           int index,
                           java.lang.Object key,
