Method Detail

getOrCreateCache

org.mule.runtime.api.metadata.MetadataCache getOrCreateCache(String id)

Returns the MetadataCache with the given id if one has already been defined. Otherwise, a new instance of MetadataCache will be created, bound to the given id and then returned.

Parameters:

id - the cache identifier hash string

Returns:

the MetadataCache bound to the given id, or a new cache of none existed.

updateCache

void updateCache(String id,
                 org.mule.runtime.api.metadata.MetadataCache cache)

Replaces the old binding of the given id with the new cache element.

Parameters:

id - the cache identifier hash string

cache - the new MetadataCache value bound to the given id

dispose

void dispose(String id)

If the given id references exactly one MetadataCache then that cache will be disposed. Otherwise, all the caches that have an id starting with the given value will be disposed, based on the pre-condition that id's are formed in a hierarchical way.

Parameters:

id - the given identifier hash string of the level at which the disposal should be performed
