Method Detail

setName

public void setName(java.lang.String name)

getName

public java.lang.String getName()

getNamePrefix

public java.lang.String getNamePrefix()

setNamePrefix

public void setNamePrefix(java.lang.String namePrefix)

execute

public void execute(java.lang.Runnable command)

Specified by:

execute in interface java.util.concurrent.Executor

execute

public void execute(java.lang.Runnable command,
                    long timeout,
                    java.util.concurrent.TimeUnit unit)

Description copied from interface: Executor

Executes the given command at some time in the future. The command may execute in a new thread, in a pooled thread, or in the calling thread, at the discretion of the Executor implementation. If no threads are available, it will be added to the work queue. If the work queue is full, the system will wait for the specified time until it throws a RejectedExecutionException

Parameters:

command - the runnable task

timeout - the length of time to wait for the task to complete

unit - the units in which timeout is expressed

initInternal

protected void initInternal()
                     throws LifecycleException

Description copied from class: LifecycleMBeanBase

Sub-classes wishing to perform additional initialization should override this method, ensuring that super.initInternal() is the first call in the overriding method.

Overrides:

initInternal in class LifecycleMBeanBase

Throws:

LifecycleException - If the initialisation fails

startInternal

protected void startInternal()
                      throws LifecycleException

Description copied from class: LifecycleBase

Sub-classes must ensure that the state is changed to LifecycleState.STARTING during the execution of this method. Changing state will trigger the Lifecycle.START_EVENT event. If a component fails to start it may either throw a LifecycleException which will cause it's parent to fail to start or it can place itself in the error state in which case LifecycleBase.stop() will be called on the failed component but the parent component will continue to start normally.

Specified by:

startInternal in class LifecycleBase

Throws:

LifecycleException - Start error occurred

stopInternal

protected void stopInternal()
                     throws LifecycleException

Description copied from class: LifecycleBase

Sub-classes must ensure that the state is changed to LifecycleState.STOPPING during the execution of this method. Changing state will trigger the Lifecycle.STOP_EVENT event.

Specified by:

stopInternal in class LifecycleBase

Throws:

LifecycleException - Stop error occurred

getDomainInternal

protected java.lang.String getDomainInternal()

Description copied from class: LifecycleMBeanBase

Method implemented by sub-classes to identify the domain in which MBeans should be registered.

Specified by:

getDomainInternal in class LifecycleMBeanBase

Returns:

The name of the domain to use to register MBeans.

getObjectNameKeyProperties

protected java.lang.String getObjectNameKeyProperties()

Description copied from class: LifecycleMBeanBase

Allow sub-classes to specify the key properties component of the ObjectName that will be used to register this component.

Specified by:

getObjectNameKeyProperties in class LifecycleMBeanBase

Returns:

The string representation of the key properties component of the desired ObjectName
