dom.NodeOffset Extends goog.Disposable
Object to store the offset from one node to another in a way that works on any similar DOM structure regardless of whether it is the same actual nodes.

Inheritance

Constructor

goog.dom.NodeOffset(nodebaseNode)

Parameters

node : Node
The node to get the offset for.
baseNode : Node
The node to calculate the offset from.

findTargetNode(baseNode) Node
Walk the dom and find the node relative to baseNode. Returns null on failure.
Arguments:
baseNode : Node
The node to start walking from. Should be equivalent to the node passed in to the constructor, in that it should have the same contents.
Returns: Node  The node relative to baseNode, or null on failure.
code »
toString() string
No description.
Returns: string  A string representation of this object.
code »
addOnDisposeCallback(callbackopt_scope)
Invokes a callback function when this object is disposed. Callbacks are invoked in the order in which they were added.
Arguments:
callback : function(this:T):?
The callback function.
opt_scope : T=
An optional scope to call the callback in.
code »
dispose() void
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 »
disposeInternal()
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');
  };

getDisposed() boolean
Use #isDisposed instead. No description.
Returns: boolean  Whether the object has been disposed of.
code »
isDisposed() boolean
No description.
Returns: boolean  Whether the object has been disposed of.
code »
registerDisposable(disposable)
Associates a disposable object with this object so that they will be disposed together.
Arguments:
disposable : goog.disposable.IDisposable
that will be disposed when this object is disposed.
