public AbstractLifeCycle()

Method Detail

isActive

public final boolean isActive()

Description copied from interface: ILifeCycle

Determine if this life-cycle object is active.

Specified by:

isActive in interface ILifeCycle

Returns:

true if the object is active

doStart

protected abstract void doStart()

Overridden in subclasses to perform custom logic on activation. Any exceptions should be thrown as a RuntimeException or subclass thereof. When this method is called, the isActive() method will return true.

doDestroy

protected abstract void doDestroy()

Overridden in subclasses to perform custom logic on destruction. Any exceptions should be thrown as a RuntimeException or subclass thereof.

start

public final void start()

Description copied from interface: ILifeCycle

Activate (start) this object. This allocates system resources required for the object to operate. This operation is idempotent.

This method may throw a RuntimeException if it fails to activate the object.

Specified by:

start in interface ILifeCycle

destroy

public final void destroy()

Description copied from interface: IDestroyable

This is called when the object is being removed from application use. This releases all system resources and performs clean up prior to the object becoming redundant. This operation is idempotent.

This method must not throw a RuntimeException.

Specified by:

destroy in interface IDestroyable

finalize

protected final void finalize()
                       throws Throwable

Overrides:

finalize in class Object

Throws:

Throwable

getLog

protected AsyncLog getLog()

Get the log to use for the object hierarchy

Returns:

the log to use for the object hierarchy

checkActive

protected void checkActive()

Check if this instance is active.

Throws:

IllegalStateException - if this is not active

toString

public String toString()

Overrides:

toString in class Object
