Method Detail

• isCached

  public boolean isCached​(java.lang.Class cls,
                          java.lang.Object identity)
                   throws PersistenceException

  Indicates whether am instance of cls is currently cached.

  Parameters:

  cls - The class type.

  identity - The object identity.

  Returns:

  True if the object is cached.

  Throws:

  PersistenceException - If a problem occured resolving the object's cache membership.

• dumpCache

  public void dumpCache()

  Dump all cached objects to log.

• dumpCache

  public void dumpCache​(java.lang.Class cls)

  Dump cached objects of specific type to log.

• expireCache

  public void expireCache()

  Expires all objects from cache.

  Objects expired from the cache will be read from persistent storage, as opposed to being read from the performance cache, during subsequent load/query operations.

  When objects are expired from the cache individually, by identity, objects contained within a "master" object, for example objects maintained in a one-to-many relationship, will automatically be expired from the cache, without the need to explicitly identify them. This does not apply when expiring objects by type. Each type, both container and contained objects need to be specified.

• expireCache

  public void expireCache​(java.lang.Class type,
                          java.lang.Object identity)
                   throws PersistenceException

  Expires a type with a specific identity from cache.

  Objects expired from the cache will be read from persistent storage, as opposed to being read from the performance cache, during subsequent load/query operations.

  When objects are expired from the cache individually, by identity, objects contained within a "master" object, for example objects maintained in a one-to-many relationship, will automatically be expired from the cache, without the need to explicitly identify them. This does not apply when expiring objects by type. Each type, both container and contained objects need to be specified.

  Parameters:

  type - The type to expire.

  identity - Identity of the object to expire.

  Throws:

  PersistenceException

• expireCache

  public void expireCache​(java.lang.Class type,
                          java.lang.Object[] identity)
                   throws PersistenceException

  Expires a type with specific identities from cache.

  Objects expired from the cache will be read from persistent storage, as opposed to being read from the performance cache, during subsequent load/query operations.

  When objects are expired from the cache individually, by identity, objects contained within a "master" object, for example objects maintained in a one-to-many relationship, will automatically be expired from the cache, without the need to explicitly identify them. This does not apply when expiring objects by type. Each type, both container and contained objects need to be specified.

  Parameters:

  type - The type to expire.

  identity - An array of object identifiers to expire.

  Throws:

  PersistenceException

• expireCache

  public void expireCache​(java.lang.Class[] type)

  Expires all instances of specified types from cache.

  Objects expired from the cache will be read from persistent storage, as opposed to being read from the performance cache, during subsequent load/query operations.

  When objects are expired from the cache individually, by identity, objects contained within a "master" object, for example objects maintained in a one-to-many relationship, will automatically be expired from the cache, without the need to explicitly identify them. This does not apply when expiring objects by type. Each type, both container and contained objects need to be specified.

  Parameters:

  type - An array of types to expire.
