Method Details

init

public void init(InitializationContext ctx)

Deprecated.

Description copied from interface: CacheLoader

Used to initialize a cache loader. Typically invoked by the PersistenceManager when setting up cache loaders.

Specified by:

init in interface CacheLoader

loadEntry

public MarshallableEntry loadEntry(Object key)
                            throws PersistenceException

Deprecated.

Description copied from interface: CacheLoader

Fetches an entry from the storage. If a MarshallableEntry needs to be created here, InitializationContext.getMarshallableEntryFactory() ()} and InitializationContext.getByteBufferFactory() should be used.

Specified by:

loadEntry in interface CacheLoader

Returns:

the entry, or null if the entry does not exist

Throws:

PersistenceException - in case of an error, e.g. communicating with the external storage

contains

public boolean contains(Object key)

Deprecated.

Description copied from interface: CacheLoader

Returns true if the storage contains an entry associated with the given key.

Specified by:

contains in interface CacheLoader

start

public void start()

Deprecated.

Specified by:

start in interface org.infinispan.commons.api.Lifecycle

storeChanged

public void storeChanged(PersistenceStatus status)

Deprecated.

Description copied from interface: PersistenceManager.StoreChangeListener

Notifies when a store was added or removed dynamically. This method is always invoked with mutual access to any other method in PersistenceManager. Implementations must only ensure visibility or atomicity of their own variables and operations.

Specified by:

storeChanged in interface PersistenceManager.StoreChangeListener

stop

public void stop()

Deprecated.

Specified by:

stop in interface org.infinispan.commons.api.Lifecycle

isCacheReady

protected boolean isCacheReady()

Deprecated.

A test to check whether the cache is in its started state. If not, calls should not be made as the channel may not have properly started, blocks due to state transfers may be in progress, etc.

Returns:

true if the cache is in its STARTED state.
