hashFn
: !goog.crypt.Hash
The hash function to use.
|
opt_blockSize
: number=
Processing block size.
|
![]()
Abort hash computation.

Returns: number
Number of bytes processed so far.

|
code » | ||
![]()
Start the hash computation.
Arguments:
|
code » | ||
![]()
Handles error.
|
code » | ||
![]()
Handle processing block loaded.
|
code » | ||
![]()
Helper function setting up the processing for the next block, or finalizing
the computation if all blocks were processed.
|
code » | ||
![]()
Sets the maximum number of bytes to hash or Infinity for no limit. Can be
called before hash() to throttle the hash computation. The hash computation
can then be continued by repeatedly calling setHashingLimit() with greater
byte offsets. This is useful if you don't need the hash until some time in
the future, for example when uploading a file and you don't need the hash
until the transfer is complete.
Arguments:

![]()
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.

Returns the parent of this event target to use for bubbling.
Returns: goog.events.EventTarget
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:
|
code » | |||||
![]()
Sets the parent of this event target to use for capture/bubble
mechanism.
Arguments:
|
code » | |||||
![]()
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'); }; |

Use
#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 » |
![]()
The blob being processed or null if no blob is being processed.
|
Code » | |
![]()
Processing block size.
|
Code » | |
![]()
Number of bytes already processed.

![]()
File reader object. Will be null if no chunk is currently being read.
|
Code » | |
The actual hash function.
|
Code » | |
![]()
Computed hash value.
|
Code » | |
![]()
The number of bytes to hash or Infinity for no limit.
|
Code » | |
The logger used by this object.
|
Code » |
The object to use for event.target. Useful when mixing in an
EventTarget to another object.

![]()

|
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.
