goog.ui.TableSorter

Adds the specified component as the last child of this component. See goog.ui.Component#addChildAt for detailed semantics.

Defined by	goog.ui.Component
Parameters	child (goog.ui.Component|null) The new child component. opt_render boolean= If true, the child component will be rendered into the parent.
See Also	goog.ui.Component#addChildAt

Adds the specified component as a child of this component at the given 0-based index.

Both addChild and addChildAt assume the following contract between parent and child components:

• the child component's element must be a descendant of the parent component's element, and
• the DOM state of the child component must be consistent with the DOM state of the parent component (see `isInDocument`) in the steady state -- the exception is to addChildAt(child, i, false) and then immediately decorate/render the child.

In particular, parent.addChild(child) will throw an error if the child component is already in the document, but the parent isn't.

Clients of this API may call addChild and addChildAt with opt_render set to true. If opt_render is true, calling these methods will automatically render the child component's element into the parent component's element. If the parent does not yet have an element, then createDom will automatically be invoked on the parent before rendering the child.

Invoking parent.addChild(child, true) will throw an error if the child component is already in the document, regardless of the parent's DOM state.

If opt_render is true and the parent component is not already in the document, enterDocument will not be called on this component at this point.

Finally, this method also throws an error if the new child already has a different parent, or the given index is out of bounds.

Defined by	goog.ui.Component
Parameters	child (goog.ui.Component|null) The new child component. index number 0-based index at which the new child component is to be added; must be between 0 and the current child count (inclusive). opt_render boolean= If true, the child component will be rendered into the parent.
Returns	Nada.
See Also	goog.ui.Component#addChild

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.

warning Deprecated	Use #listen instead, when possible. Otherwise, use goog.events.listen if you are passing Object (instead of Function) as handler.

Defined by

goog.events.EventTarget

Parameters

type (string|goog.events.EventId) The type of the event to listen for handler (function(?): ?|{handleEvent: function(?): ?}|null) The function to handle the event. The handler can also be an object that implements the handleEvent method which takes the event object as argument. opt_capture boolean= In DOM-compliant browsers, this determines whether the listener is fired during the capture or bubble phase of the event. opt_handlerScope (Object|null)= Object in whose scope to call the listener.

Invokes a callback function when this object is disposed. Callbacks are invoked in the order in which they were added. If a callback is added to an already disposed Disposable, it will be called immediately.

Defined by	goog.Disposable
Parameters	callback function(): ? The callback function. opt_scope (T|null)= An optional scope to call the callback in.

Determines if a given element can be decorated by this type of component. This method should be overridden by inheriting objects.

Overrides	goog.ui.Component
Parameters	element (Element|null) Element to decorate.
Returns	boolean True if the element can be decorated, false otherwise.

Creates the initial DOM representation for the component. The default implementation is to set this.element_ = div.

Decorates the element for the UI component. If the element is in the document, the enterDocument method will be called.

If goog.ui.Component.ALLOW_DETACHED_DECORATION is false, the caller must pass an element that is in the document.

Defined by	goog.ui.Component
Parameters	element (Element|null) Element to decorate.

Actually decorates the element. Should be overridden by inheriting objects. This method can assume there are checks to ensure the component has not already been rendered have occurred and that enter document will be called afterwards. This method is considered protected.

Defined by	goog.ui.Component
Parameters	element (Element|null) Element to decorate.

Dispatches an event (or event like object) and calls all listeners listening for events of this type. The type of the event is decided by the type property on the event object.

If any of the listeners returns false OR calls preventDefault then this function will return false. If one of the capture listeners calls stopPropagation, then the bubble listeners won't fire.

Overrides	goog.events.EventTarget
Specified by	goog.events.Listenable
Parameters	e (string|Object|null) Event object.
Returns	boolean If anyone called preventDefault on the event object (or if any of the listeners returns false) this will also return false.

Disposes of the object and its resources.

Overrides	goog.Disposable
Specified by	goog.disposable.IDisposable
Parameters	None.
Returns	Nothing.

Disposes of the component. Calls exitDocument, which is expected to remove event handlers and clean up the component. Propagates the call to the component's children, if any. Removes the component's DOM from the document unless it was decorated.

Defined by	goog.ui.Component
Overrides	goog.events.EventTarget
Parameters	None.

Called when the component's element is known to be in the document. Anything using document.getElementById etc. should be done at this stage.

If the component contains child components, this call is propagated to its children.

Overrides	goog.ui.Component
Parameters	None.

Called by dispose to clean up the elements and listeners created by a component, or by a parent component/application who has removed the component from the document but wants to reuse it later.

If the component contains child components, this call is propagated to its children.

It should be possible for the component to be rendered again once this method has been called.

Fires all registered listeners in this listenable for the given type and capture mode, passing them the given eventObject. This does not perform actual capture/bubble. Only implementors of the interface should be using this.

Overrides	goog.events.EventTarget

Parameters	type (string|goog.events.EventId<(EVENTOBJ|null)>) The type of the listeners to fire. capture boolean The capture mode of the listeners to fire. eventObject (EVENTOBJ|null) The event object to fire.
Returns	boolean Whether all listeners succeeded without attempting to prevent default behavior. If any listener returns false or called goog.events.Event#preventDefault, this returns false.

Calls the given function on each of this component's children in order. If opt_obj is provided, it will be used as the 'this' object in the function when called. The function should take two arguments: the child component and its 0-based index. The return value is ignored.

Defined by	goog.ui.Component
Parameters	f function(?, number): ? The function to call for every child component; should take 2 arguments (the child and its index). opt_obj (T|null)= Used as the 'this' object in f when called.

Parameters	type (string|goog.events.EventId<(EVENTOBJ|null)>) The event type id. listener function((EVENTOBJ|null)): (boolean|undefined) Callback method. opt_useCapture boolean= Whether to fire in capture phase (defaults to false). opt_listenerScope (SCOPE|null)= Object in whose scope to call the listener.
Returns	goog.events.ListenableKey Unique key for the listener.

Adds an event listener that is removed automatically after the listener fired once.

If an existing listener already exists, listenOnce will do nothing. In particular, if the listener was previously registered via listen(), listenOnce() will not turn the listener into a one-off listener. Similarly, if there is already an existing one-off listener, listenOnce does not modify the listeners (it is still a once listener).

Defined by	goog.ui.Component
Parameters	idFragment string A partial id.
Returns	string Unique element id.

Makes a collection of ids. This is a convenience method for makeId. The object's values are the id fragments and the new values are the generated ids. The key will remain the same.

Defined by	goog.ui.Component
Parameters	object (Object|null) The object that will be used to create the ids.
Returns	Object<string, string> An object of id keys to generated ids.

Returns whether this component should listen for PointerEvent types rather than MouseEvent types. This allows supporting drag gestures for touch/stylus input.

Parameters	None.
Returns	boolean

Associates a disposable object with this object so that they will be disposed together.

Defined by	goog.Disposable
Parameters	disposable (goog.disposable.IDisposable|null) that will be disposed when this object is disposed.

Removes all listeners from this listenable. If type is specified, it will only remove listeners of the particular type. otherwise all registered listeners will be removed.

Specified by	goog.events.Listenable
Parameters	opt_type (string|goog.events.EventId)= Type of event to remove, default is to remove all types.
Returns	number Number of listeners removed.

Removes the given child from this component, and returns it. Throws an error if the argument is invalid or if the specified child isn't found in the parent component. The argument can either be a string (interpreted as the ID of the child component to remove) or the child component itself.

If opt_unrender is true, calls goog.ui.component#exitDocument on the removed child, and subsequently detaches the child's DOM from the document. Otherwise it is the caller's responsibility to clean up the child component's DOM.

Defined by	goog.ui.Component
Parameters	child (string|goog.ui.Component|null) The ID of the child to remove, or the child component itself. opt_unrender boolean= If true, calls exitDocument on the removed child component, and detaches its DOM from the document.

Defined by	goog.ui.Component
Parameters	index number 0-based index of the child to remove. opt_unrender boolean= If true, calls exitDocument on the removed child component, and detaches its DOM from the document.
Returns	(goog.ui.Component|null) The removed component, if any.
See Also	goog.ui.Component#removeChild

Removes every child component attached to this one and returns them.

Defined by	goog.ui.Component

Returns	Array<(goog.ui.Component|null)> The removed components if any.
See Also	goog.ui.Component#removeChild

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.

warning Deprecated	Use #unlisten instead, when possible. Otherwise, use goog.events.unlisten if you are passing Object (instead of Function) as handler.

Defined by

goog.events.EventTarget

Parameters

type (string|goog.events.EventId) The type of the event to listen for handler (function(?): ?|{handleEvent: function(?): ?}|null) The function to handle the event. The handler can also be an object that implements the handleEvent method which takes the event object as argument. opt_capture boolean= In DOM-compliant browsers, this determines whether the listener is fired during the capture or bubble phase of the event. opt_handlerScope (Object|null)= Object in whose scope to call the listener.

Renders the component. If a parent element is supplied, the component's element will be appended to it. If there is no optional parent element and the element doesn't have a parentNode then it will be appended to the document body.

If this component has a parent component, and the parent component is not in the document already, then this will not call enterDocument on this component.

Throws an Error if the component is already rendered.

Defined by	goog.ui.Component
Parameters	opt_parentElement (Element|null)= Optional parent element to render the component into.

Renders the component before another element. The other element should be in the document already.

Throws an Error if the component is already rendered.

Defined by	goog.ui.Component
Parameters	sibling (Node|null) Node to render the component before.

Sets the default sort function to be used by all columns. If not set explicitly, this defaults to numeric sorting.

Parameters	sortFunction function(*, *): number The new default sort function.

Sets the component's root element to the given element. Considered protected and final.

This should generally only be called during createDom. Setting the element does not actually change which element is rendered, only the element that is associated with this UI component.

This should only be used by subclasses and its associated renderers.

Defined by	goog.ui.Component
Parameters	element (Element|null) Root element for the component.

Assigns an ID to this component instance. It is the caller's responsibility to guarantee that the ID is unique. If the component is a child of a parent component, then the parent component's child index is updated to reflect the new ID; this may throw an error if the parent already has a child with an ID that conflicts with the new ID.

Defined by	goog.ui.Component
Parameters	id string Unique component ID.

Sets the model associated with the UI component.

Defined by	goog.ui.Component
Parameters	obj * The model.

Sets the parent of this component to use for event bubbling. Throws an error if the component already has a parent or if an attempt is made to add a component to itself as a child. Callers must use removeChild or removeChildAt to remove components from their containers before calling this method.

Defined by	goog.ui.Component
Parameters	parent (goog.ui.Component|null) The parent component.
See Also	goog.ui.Component#removeChild goog.ui.Component#removeChildAt
