Deprecated. Use the Avalon Excalibur Store instead.

public class StoreJanitorImpl
extends AbstractLogEnabled
implements StoreJanitor, Configurable, ThreadSafe, Runnable, Startable

This class is a implentation of a StoreJanitor. Store classes can register to the StoreJanitor. When memory is too low, the StoreJanitor frees the registered caches until memory is normal.

Method Detail

configure

public void configure(Configuration conf)
               throws ConfigurationException

Deprecated.

Initialize the StoreJanitorImpl. A few options can be used :

• freememory = how many bytes shall be always free in the jvm
• heapsize = max. size of jvm memory consumption
• cleanupthreadinterval = how often (sec) shall run the cleanup thread
• threadpriority = priority of the thread (1-10). (Default: 10)

Specified by:

configure in interface Configurable

Parameters:

conf - the Configuration of the application

Throws:

ConfigurationException

start

public void start()

Deprecated.

Specified by:

start in interface Startable

stop

public void stop()

Deprecated.

Specified by:

stop in interface Startable

run

public void run()

Deprecated.

The "checker" thread checks if memory is running low in the jvm.

Specified by:

run in interface Runnable

register

public void register(Store store)

Deprecated.

This method register the stores

Specified by:

register in interface StoreJanitor

Parameters:

store - the store to be registered

unregister

public void unregister(Store store)

Deprecated.

This method unregister the stores

Specified by:

unregister in interface StoreJanitor

Parameters:

store - the store to be unregistered

iterator

public Iterator iterator()

Deprecated.

This method return a java.util.Iterator of every registered stores The iterators returned is fail-fast: if list is structurally modified at any time after the iterator is created, in any way, the iterator will throw a ConcurrentModificationException. Thus, in the face of concurrent modification, the iterator fails quickly and cleanly, rather than risking arbitrary, non-deterministic behavior at an undetermined time in the future.

Specified by:

iterator in interface StoreJanitor

Returns:

a java.util.Iterator
