Field Detail

logger

protected final org.apache.commons.logging.Log logger

context

protected MuleContext context

scheduler

protected ScheduledThreadPoolExecutor scheduler

maxEntries

protected int maxEntries

the maximum number of entries that this store keeps around. Specify -1 if the store is supposed to be "unbounded".

entryTTL

protected int entryTTL

The time-to-live for each message ID, specified in milliseconds, or -1 for entries that should never expire. DO NOT combine this with an unbounded store!

expirationInterval

protected int expirationInterval

The interval for periodic bounded size enforcement and entry expiration, specified in milliseconds. Arbitrary positive values between 1 millisecond and several hours or days are possible, but should be chosen carefully according to the expected message rate to prevent out of memory conditions.

name

protected String name

A name for this store, can be used for logging and identification purposes.

Method Detail

initialise

public void initialise()
                throws InitialisationException

Description copied from interface: Initialisable

Method used to perform any initialisation work. If a fatal error occurs during initialisation an InitialisationException should be thrown, causing the Mule instance to shutdown. If the error is recoverable, say by retrying to connect, a RecoverableException should be thrown. There is no guarantee that by throwing a Recoverable exception that the Mule instance will not shut down.

Specified by:

initialise in interface Initialisable

Throws:

InitialisationException - if a fatal error occurs causing the Mule instance to shutdown

RecoverableException - if an error occurs that can be recovered from

run

public final void run()

Specified by:

run in interface Runnable

dispose

public void dispose()

Description copied from interface: Disposable

A lifecycle method where implementor should free up any resources. If an exception is thrown it should just be logged and processing should continue. This method should not throw Runtime exceptions.

Specified by:

dispose in interface Disposable

getMuleContext

protected MuleContext getMuleContext()

setEntryTTL

public void setEntryTTL(int entryTTL)

setExpirationInterval

public void setExpirationInterval(int expirationInterval)

setMaxEntries

public void setMaxEntries(int maxEntries)

setScheduler

public void setScheduler(ScheduledThreadPoolExecutor scheduler)

setName

public void setName(String id)

setMuleContext

public void setMuleContext(MuleContext context)

Specified by:

setMuleContext in interface MuleContextAware

getEntryTTL

public int getEntryTTL()

getExpirationInterval

public int getExpirationInterval()

getMaxEntries

public int getMaxEntries()

getName

public String getName()

getScheduler

public ScheduledThreadPoolExecutor getScheduler()

expire

protected abstract void expire()
