getLockObject

public Object getLockObject()

Description copied from interface: AccessibleLock

Returns the reference to the object that is synchronized on by other methods in the implementing class. This reference is not permitted to change after construction, so this method can be called once and the reference saved.

This reference can be used in synchronized blocks to keep other threads from sneaking in between methods calls like this:

obj = //... synchronized ( obj.getLockObject() ) { obj.methodA(); obj.methodB(); }

Specified by:

getLockObject in interface AccessibleLock

Following copied from interface: com.jthreadkit.AccessibleLock

Returns:

the object used to lock on to control concurrent access.

public boolean addConfigChangeListener(ConfigChangeListener listener)

Specified by:

addConfigChangeListener in interface ResourcePool

removeConfigChangeListener

public boolean removeConfigChangeListener(ConfigChangeListener listener)

Specified by:

initiateShutdown

public void initiateShutdown(long msDelayBeforeHardball)

Specified by:

waitUntilShutdown

public boolean waitUntilShutdown(long msTimeout)
                          throws InterruptedException
