  +--javax.swing.TimerQueue

All Implemented Interfaces:

Runnable

class TimerQueue

extends Object

implements Runnable

Field Summary

private static Object	classLock
private static Object	expiredTimersKey
(package private) Timer	firstTimer
(package private) boolean	running
private static Object	sharedInstanceKey

Constructor Summary

TimerQueue()
Constructor for TimerQueue.

Method Summary

(package private) void	addTimer(Timer timer, long expirationTime)
(package private) boolean	containsTimer(Timer timer)
(package private) long	postExpiredTimers() If there are a ton of timers, this method may never return.
(package private) void	removeTimer(Timer timer)
void	run() Enabled: When an object implementing interface Runnable is used to create a thread, starting the thread causes the object's run method to be called in that separately executing thread.
static TimerQueue	sharedInstance()
(package private) void	start()
(package private) void	stop()
String	toString() Suppressed: Returns a string representation of the object.

sharedInstanceKey

private static final Object sharedInstanceKey

expiredTimersKey

private static final Object expiredTimersKey

Constructor Detail

TimerQueue

public TimerQueue()

Constructor for TimerQueue.

Method Detail

sharedInstance

public static TimerQueue sharedInstance()

start

void start()

stop

void stop()

addTimer

void addTimer(Timer timer,
              long expirationTime)

removeTimer

void removeTimer(Timer timer)

containsTimer

boolean containsTimer(Timer timer)

postExpiredTimers

long postExpiredTimers()

If there are a ton of timers, this method may never return. It loops checking to see if the head of the Timer list has expired. If it has, it posts the Timer and reschedules it if necessary.

run

public void run()

Description copied from interface: Runnable

Enabled: When an object implementing interface Runnable is used to create a thread, starting the thread causes the object's run method to be called in that separately executing thread.

The general contract of the method run is that it may take any action whatsoever.

Specified by:

run in interface Runnable

java.lang.Thread#run()

toString

public String toString()

Description copied from class: Object

Suppressed: Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.

The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:

 getClass().getName() + '@' + Integer.toHexString(hashCode())
 

Overrides:

toString in class Object

Returns:

a string representation of the object.
