Class DefaultPersistentMetadataCacheManager

java.lang.Object

org.mule.runtime.metadata.internal.cache.DefaultPersistentMetadataCacheManager

All Implemented Interfaces:

org.mule.runtime.api.lifecycle.Startable, MetadataCacheManager

public class DefaultPersistentMetadataCacheManager
extends Object
implements MetadataCacheManager, org.mule.runtime.api.lifecycle.Startable

Default implementation of a MetadataCacheManager. This implementation provides a way of managing persistent MetadataCaches that are stored at container-level using the ObjectStore as handler for the persistence. Cache's are never evicted, and will be cleared only when an explicit disposal is invoked.

Since:

4.1.4, 4.2.0

Method Detail

setLockFactory

public void setLockFactory(org.mule.runtime.api.lock.LockFactory lockFactory)

setObjectStoreManager

public void setObjectStoreManager(org.mule.runtime.api.store.ObjectStoreManager objectStoreManager)

start

public void start()

Specified by:

start in interface org.mule.runtime.api.lifecycle.Startable

getOrCreateCache

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

Description copied from interface: MetadataCacheManager

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.

Specified by:

getOrCreateCache in interface MetadataCacheManager

Parameters:

id - the cache identifier hash string

Returns:

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

updateCache

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

Description copied from interface: MetadataCacheManager

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

Specified by:

updateCache in interface MetadataCacheManager

Parameters:

id - the cache identifier hash string

cache - the new MetadataCache value bound to the given id

dispose

public void dispose(String keyHash)

Description copied from interface: MetadataCacheManager

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.

Specified by:

dispose in interface MetadataCacheManager

Parameters:

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