Method Detail

containsObjectMapping

public boolean containsObjectMapping(java.lang.Object mappingKey)

Description copied from interface: IObjectMappingCache

Returns true if this cache instance contains an object method for the given mappingKey.

Specified by:

containsObjectMapping in interface IObjectMappingCache

Parameters:

mappingKey - The method key to check if the cache contains an object method for.

Returns:

True if the cache contains object mappings for the given method key. False if not.

getObjectMapping

public IObjectMapping getObjectMapping(java.lang.Object mappingKey)

Description copied from interface: IObjectMappingCache

Returns the object-to-database method for the given method key, stored in this object method cache. If no object method is stored in the cache null is returned.

Specified by:

getObjectMapping in interface IObjectMappingCache

Returns:

The object method matching the given method key. Null if no object method was found for the given method key.

storeObjectMapping

                               IObjectMapping mapping)

Description copied from interface: IObjectMappingCache

Stores the given object-to-database method in this object method cache, under the given method key.

Specified by:

storeObjectMapping in interface IObjectMappingCache

Parameters:

mappingKey - The method key to store this object method under.

mapping - The object method to store.

removeObjectMapping

public void removeObjectMapping(java.lang.Object mappingKey)

Description copied from interface: IObjectMappingCache

Specified by:

removeObjectMapping in interface IObjectMappingCache

Parameters:

mappingKey - The key to give this particular object method.

clear

public void clear()

Description copied from interface: IObjectMappingCache

Removes all object mappings stored in this cache.

Specified by:

clear in interface IObjectMappingCache

size
