An abstract class that provides the core functionality for draw a chart axis. Axis is used by the following classes:
_addAttrscfgs
values
lazy
Implementation behind the public addAttrs method.
This method is invoked directly by get if it encounters a scenario in which an attribute's valueFn attempts to obtain the value an attribute in the same group of attributes, which has not yet been added (on demand initialization).
cfgs
Object
An object with attribute name/configuration pairs.
values
Object
An object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
lazy
Boolean
Whether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.
_addLazyAttrname
[lazyCfg]
Finishes initializing an attribute which has been lazily added.
_addOutOfOrdername
cfg
Utility method used by get/set to add attributes encountered out of order when calling addAttrs().
For example, if:
this.addAttrs({
foo: {
setter: function() {
// make sure this bar is available when foo is added
this.get("bar");
}
},
bar: {
value: ...
}
});_afterChildSelectedChangeevent

attribute, responsible for updating the UI, in response to
attribute changes.
event

The event facade for the attribute change.
_aggregateAttrsallAttrs
A helper method, used by _initHierarchyData to aggregate attribute configuration across the instances class hierarchy.
The method will protect the attribute configuration value to protect the statically defined default value in ATTRS if required (if the value is an object literal, array or the attribute configuration has cloneDefaultValue set to shallow or deep).
allAttrs
Array
An array of ATTRS definitions across classes in the hierarchy (subclass first, Base last)
The aggregate set of ATTRS definitions for the instance
_applyParserconfig
Utility method used to apply the HTML_PARSER configuration for the
instance, to retrieve config data values.

attrs
Array
_bindDOMSets up DOM listeners, on elements rendered by the widget.
_bindUISets up DOM and CustomEvent listeners for the widget.
_bindUIChildBinds event listeners responsible for updating the UI state in response to WidgetChild related state changes.
This method is invoked after bindUI is invoked for the Widget class using YUI's aop infrastructure.
_clearLabelCacheRemoves axis labels from the dom and clears the label cache.
_cloneDefaultValuecfg
This method assumes that the value has already been checked to be an object. Since it's on a critical path, we don't want to re-do the check.
cfg
Object
_createLabelCacheCreates a cache of labels that can be re-used when the axis redraws.
_createUIEventtype
Binds a delegated DOM event listener of the specified type to the Widget's outtermost DOM element to facilitate the firing of a Custom Event of the same type for the Widget instance.

eventFastPath
Boolean
Whether or not we're using this as a fast path in the case of no listeners or not
_defaultBBReturns the default value for the boundingBox attribute.
For the Widget class, this will most commonly be null (resulting in a new boundingBox node instance being created), unless a srcNode was provided and CONTENT_TEMPLATE is null, in which case it will be srcNode. This behavior was introduced in @VERSION@ to accomodate single-box widgets whose BB & CB both point to srcNode (e.g. Y.Button).
_defaultCBReturns the default value for the contentBox attribute.
For the Widget class, this will be the srcNode if provided, otherwise null (resulting in a new contentBox node instance being created)

_drawAxisDraws an axis.
_filterAdHocAttrsallAttrs

userVals
Object
The config object passed in by the user, from which adhoc attrs are to be filtered.
The set of adhoc attributes passed in, in the form of an object with attribute name/configuration pairs.
_filterUIEventevt
This method is used to determine if we should fire the UI Event or not. The default implementation makes sure that for nested delegates (nested unrelated widgets), we don't fire the UI event listener more than once at each level.
For example, without the additional filter, if you have nested widgets, each widget will have a delegate listener. If you click on the inner widget, the inner delegate listener's filter will match once, but the outer will match twice (based on delegate's design) - once for the inner widget, and once for the outer.

addAttrname
config
lazy
Adds an attribute with the provided configuration to the host object.
The config argument object supports the following properties:
A function, which will return the initial value to set on the attribute. This is useful for cases where the attribute configuration is defined statically, but needs to reference the host instance ("this") to obtain an initial value. If both the value and valueFn properties are defined, the value returned by the valueFn has precedence over the value property, unless it returns undefined, in which case the value property is used.
valueFn can also be set to a string, representing the name of the instance method to be used to retrieve the value.
The writeOnce attribute can also be set to the string "initOnly", in which case the attribute can only be set during initialization (when used with Base, this means it can only be set during construction)
The setter function used to massage or normalize the value passed to the set method for the attribute. The value returned by the setter will be the final stored value. Returning Attribute.INVALID_VALUE, from the setter will prevent the value from being stored.
setter can also be set to a string, representing the name of the instance method to be used as the setter function.
The getter function used to massage or normalize the value returned by the get method for the attribute. The value returned by the getter function is the value which will be returned to the user when they invoke get.
getter can also be set to a string, representing the name of the instance method to be used as the getter function.
The validator function invoked prior to setting the stored value. Returning false from the validator function will prevent the value from being stored.
validator can also be set to a string, representing the name of the instance method to be used as the validator function.
The setter, getter and validator are invoked with the value and name passed in as the first and second arguments, and with the context ("this") set to the host object.

name
String

endPoint
line
Draws a line segment between 2 points

enableSet the Widget's "disabled" attribute to "false".
firetype
arguments
Fire a custom event by name. The callback functions will be executed from the context specified when the event was created, and with the following parameters.
The first argument is the event type, and any additional arguments are passed to the listeners as parameters. If the first of these is an object literal, and the event is configured to emit an event facade, that object is mixed into the event facade and the facade is provided in place of the original object.
If the custom event object hasn't been created, then the event hasn't been published and it has no subscribers. For performance sake, we immediate exit in this case. This means the event won't bubble, so if the intention is that a bubble target be notified, the event must be published on this object first.
type
String | Object
The type of the event, or an object that contains a 'type' property.
arguments
Object*
an arbitrary set of parameters to pass to the handler. If the first of these is an object literal and the event is configured to emit an event facade, the event facade will replace that parameter after the properties the object literal contains are copied to the event facade.
True if the whole lifecycle of the event went through, false if at any point the event propagation was halted.
focusCauses the Widget to receive the focus by setting the "focused" attribute to "true".
getname
Returns the current value of the attribute. If the attribute has been configured with a 'getter' function, this method will delegate to the 'getter' to obtain the value of the attribute.
name
String
The name of the attribute. If the value of the attribute is an Object,
dot notation can be used to obtain the value of a property of the object (e.g. get("x.y.z"))
The value of the attribute
getAttrsattrs
Gets multiple attribute values.
An object with attribute name/value pairs.
getClassNameargs
Generate a standard prefixed classname for the Widget, prefixed by the default prefix defined
by the Y.config.classNamePrefix attribute used by ClassNameManager and
Widget.NAME.toLowerCase() (e.g. "yui-widget-xxxxx-yyyyy", based on default values for
the prefix and widget class name).
The instance based version of this method can be used to generate standard prefixed classnames, based on the instances NAME, as opposed to Widget.NAME. This method should be used when you need to use a constant class name across different types instances.
args
String*
multiple

fn
[context]
[arg*]
Subscribe a callback function to a custom event fired by this object or from an object that bubbles its events to this object.
Callback functions for events published with emitFacade = true will
receive an EventFacade as the first argument (typically named "e").
These callbacks can then call e.preventDefault() to disable the
behavior published to that event's defaultFn. See the EventFacade
API for all available properties and methods. Subscribers to
non-emitFacade events will receive the arguments passed to fire()
after the event name.
To subscribe to multiple events at once, pass an object as the first argument, where the key:value pairs correspond to the eventName:callback, or pass an array of event names as the first argument to subscribe to all listed events with the same callback.
Returning false from a callback is supported as an alternative to
calling e.preventDefault(); e.stopPropagation();. However, it is
recommended to use the event methods whenever possible.

renderparentNode
Establishes the initial DOM for the widget. Invoking this method will lead to the creating of all DOM elements for the widget (or the manipulation of existing DOM elements for the progressive enhancement use case).
This method should only be invoked once for an initialized widget.
It delegates to the widget specific renderer method to do the actual work.
parentNode
Object | String
Optional. The Node under which the Widget is to be rendered. This can be a Node instance or a CSS selector string.
If the selector string returns more than one Node, the first node will be used as the parentNode.

If it's not provided, the Widget will be rendered to the body of the current document in this case.
rendererCreates DOM (or manipulates DOM for progressive enhancement) This method is invoked by render() and is not chained automatically for the class hierarchy (unlike initializer, destructor) so it should be chained manually for subclasses if required.

Fires when the value for the configuration attribute visible is
changed. You can listen for the event using the on method if you
wish to be notified before the attribute's value has changed, or
using the after method if you wish to be notified after the
attribute's value has changed.

widthWhen set, defines the width of a vertical axis instance. By default, vertical axes automatically size based on their contents. When the width attribute is set, the axis will not calculate its width. When the width attribute is explicitly set, axis labels will postion themselves off of the the inner edge of the axis and the title, if present, will position itself off of the outer edge. If a specified width is less than the sum of the axis' contents, excess content will overflow.
widthChange
Fires when the value for the configuration attribute width is
changed. You can listen for the event using the on method if you
wish to be notified before the attribute's value has changed, or
using the after method if you wish to be notified after the
attribute's value has changed.

EventFacade
destroyLifecycle event for the destroy phase, fired prior to destruction. Invoking the preventDefault method on the event object provided to subscribers will prevent destruction from proceeding.
Subscribers to the "after" moment of this event, will be notified after destruction is complete (and as a result cannot prevent destruction).

EventFacade
Event object
initLifecycle event for the init phase, fired prior to initialization. Invoking the preventDefault() method on the event object provided to subscribers will prevent initialization from occuring.
Subscribers to the "after" momemt of this event, will be notified after initialization of the object is complete (and therefore cannot prevent initialization).
e
EventFacade
Event object, with a cfg property which refers to the configuration object passed to the constructor.
renderLifecycle event for the render phase, fired prior to rendering the UI for the widget (prior to invoking the widget's renderer method).
Subscribers to the "on" moment of this event, will be notified before the widget is rendered.
Subscribers to the "after" moment of this event, will be notified after rendering is complete.

The Event Facade
widget:contentUpdateNotification event, which widget implementations can fire, when they change the content of the widget. This event has no default behavior and cannot be prevented, so the "on" or "after" moments are effectively equivalent (with on listeners being invoked before after listeners).
