opt_interval
: number=
Number of ms between ticks (Default: 1ms).
|
opt_timerObject
: Object=
An object that has setTimeout, setInterval,
clearTimeout and clearInterval (eg Window).
|
![]()
Dispatches the TICK event. This is its own method so subclasses can override.

Gets the interval of the timer.
Returns: number
interval Number of ms between ticks.
|
code » | ||
![]()
Sets the interval of the timer.
Arguments:
|
code » | ||
![]()
Starts the timer.
|
code » | ||
![]()
Stops the timer.
|
code » | ||
![]()
Callback for the setTimeout used by the timer

![]()
Use
#listen instead, when possible. Otherwise, use
goog.events.listen if you are passing Object
(instead of Function) as handler.
Adds an event listener to the event target. The same handler can only be
added once per the type. Even if you add the same handler multiple times
using the same type then it will only be called once when the event is
dispatched.
Arguments:
|

![]()
Asserts that the event target instance is initialized properly.

![]()
Removes listeners from this object. Classes that extend EventTarget may
need to override this method in order to remove references to DOM Elements
and additional listeners.

The parent EventTarget or null if
there is no parent.

![]()
Use
#unlisten instead, when possible. Otherwise, use
goog.events.unlisten if you are passing Object
(instead of Function) as handler.
Removes an event listener from the event target. The handler must be the
same object as the one added. If the handler has not been added then
nothing is done.
Arguments:
|

![]()
Sets the parent of this event target to use for capture/bubble
mechanism.
Arguments:

![]()
Sets the target to be used for
event.target when firing
event. Mainly used for testing. For example, see
goog.testing.events.mixinListenable .

![]()
Invokes a callback function when this object is disposed. Callbacks are
invoked in the order in which they were added.
Arguments:
|
code » | |||
![]()
Disposes of the object. If the object hasn't already been disposed of, calls
#disposeInternal . Classes that extend goog.Disposable should
override #disposeInternal in order to delete references to COM
objects, DOM nodes, and other disposable objects. Reentrant.
Returns: void
Nothing.
|
code » | |||
![]()
Deletes or nulls out any references to COM objects, DOM nodes, or other
disposable objects. Classes that extend
goog.Disposable should
override this method.
Not reentrant. To avoid calling it twice, it must only be called from the
subclass' disposeInternal method. Everywhere else the public
dispose method must be used.
For example:
mypackage.MyClass = function() { mypackage.MyClass.base(this, 'constructor'); // Constructor logic specific to MyClass. ... }; goog.inherits(mypackage.MyClass, goog.Disposable); mypackage.MyClass.prototype.disposeInternal = function() { // Dispose logic specific to MyClass. ... // Call superclass's disposeInternal at the end of the subclass's, like // in C++, to avoid hard-to-catch issues. mypackage.MyClass.base(this, 'disposeInternal'); }; |

#isDisposed instead.

Returns: boolean
Whether the object has been disposed of.

![]()
Associates a disposable object with this object so that they will be disposed
together.
Arguments:

code » |
![]()
Cached tick_ bound to the object for later use in the timer.
|

![]()

|
Code » | |
![]()
Whether this timer is enabled
|

![]()
Number of ms between ticks

![]()
Firefox browser often fires the timer event sooner
(sometimes MUCH sooner) than the requested timeout. So we
compare the time to when the event was last fired, and
reschedule if appropriate. See also goog.Timer.intervalScale

![]()
An object that implements setTimeout, setInterval, clearTimeout and
clearInterval. We default to the window object. Changing this on
goog.Timer.prototype changes the object for all timer instances which can
be useful if your environment has some other implementation of timers than
the window object.
|
Code » | |
![]()
Variable for storing the result of setInterval
|
Code » |
The object to use for event.target. Useful when mixing in an
EventTarget to another object.
|
Code » | |
![]()
No description.
|
Code » | |
Maps of event type to an array of listeners.
|
Code » | |
Parent event target, used during event bubbling.
TODO(user): Change this to goog.events.Listenable. This
currently breaks people who expect getParentEventTarget to return
goog.events.EventTarget.
|
Code » |
Calls the given function once, after the optional pause.
The function is always called asynchronously, even if the delay is 0. This
is a common trick to schedule a function to run after a batch of browser
event processing.
Arguments:
Returns: number
A handle to the timer ID.
|
code » | ||||
![]()
Clears a timeout initiated by callOnce
Arguments:
|
code » |
![]()
Maximum timeout value.
Timeout values too big to fit into a signed 32-bit integer may cause
overflow in FF, Safari, and Chrome, resulting in the timeout being
scheduled immediately. It makes more sense simply not to schedule these
timeouts, since 24.8 days is beyond a reasonable expectation for the
browser to stay open.
|
Code » | |
![]()
Constant for the timer's event type
|
Code » | |
![]()
An object that implements setTimout, setInterval, clearTimeout and
clearInterval. We default to the global object. Changing
goog.Timer.defaultTimerObject changes the object for all timer instances
which can be useful if your environment has some other implementation of
timers you'd like to use.
|
Code » | |
![]()
A variable that controls the timer error correction. If the
timer is called before the requested interval times
intervalScale, which often happens on mozilla, the timer is
rescheduled. See also this.last_
