Methods

Methods

_addAttrs

(
  • cfgs
  • values
  • lazy
)
private

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).

Parameters:

  • 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.

_addLazyAttr

(
  • name
  • [lazyCfg]
)
private

Finishes initializing an attribute which has been lazily added.

Parameters:

  • name Object

    The name of the attribute

  • [lazyCfg] Object optional

    Optional config hash for the attribute. This is added for performance along the critical path, where the calling method has already obtained lazy config from state.

_addOutOfOrder

(
  • name
  • cfg
)
private

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: ...
 }
});

Parameters:

  • name String

    attribute name

  • cfg Object

    attribute configuration

_afterChildSelectedChange

(
  • event
)
protected

Default attribute change listener for the selected attribute, responsible for updating the UI, in response to attribute changes.

Parameters:

  • event EventFacade

    The event facade for the attribute change.

_aggregateAttrs

(
  • allAttrs
)
Object private

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).

Parameters:

  • allAttrs Array

Returns:

Object :

The aggregate set of ATTRS definitions for the instance

_applyParsedConfig

() Object protected

Returns:

Object :

The merged configuration literal

Removes axis labels from the dom and clears the label cache.

_cloneDefaultValue

(
  • cfg
)
private

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.

Parameters:

Inherited from Axis: charts/js/Axis.js:765

Creates a cache of labels that can be re-used when the axis redraws.

_createUIEvent

(
  • type
)
private

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.

Parameters:

  • type String

    String representing the name of the event

_dataChangeHandler

    Whether or not we're using this as a fast path in the case of no listeners or not

_defaultBB

() protected

Returns 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).

_defaultCB

() protected

Returns 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)

  • userVals
)
Object private

Parameters:

  • userVals Object

    The config object passed in by the user, from which adhoc attrs are to be filtered.

Returns:

Object :

The set of adhoc attributes passed in, in the form of an object with attribute name/configuration pairs.

_filterUIEvent

(
  • evt
)
Boolean private

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.

Parameters:

Returns:

Boolean :

true if it's OK to fire the custom UI event, false if not.

Parameters:

addAttr

(
  • name
  • config
  • lazy
)
Object chainable

Adds an attribute with the provided configuration to the host object.

The config argument object supports the following properties:

value <Any>
The initial value to set on the attribute
valueFn <Function | String>

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.

readOnly <boolean>
Whether or not the attribute is read only. Attributes having readOnly set to true cannot be modified by invoking the set method.
writeOnce <boolean> or <string>
Whether or not the attribute is "write once". Attributes having writeOnce set to true, can only have their values set once, be it through the default configuration, constructor configuration arguments, or by invoking set.

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)

setter <Function | String>

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.

getter <Function | String>

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.

validator <Function | String>

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.

lazyAdd <boolean>
Whether or not to delay initialization of the attribute until the first call to get/set it. This flag can be used to over-ride lazy initialization on a per attribute basis, when adding multiple attributes through the addAttrs method.

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.

Configuration properties outside of the list mentioned above are considered private properties used internally by attribute, and are not intended for public use.

Parameters:

  • name String

    The name of the attribute.

  • config Object

    An object with attribute configuration property/value pairs, specifying the configuration for the attribute.

    NOTE: The configuration object is modified when adding an attribute, so if you need to protect the original values, you will need to merge the object.

  • lazy Boolean

    (optional) Whether or not to add this attribute lazily (on the first call to get/set).

Returns:

Object :

A reference to the host object.

addAttrs

(
  • cfgs
  • values
  • lazy
)
Object chainable

Configures a group of attributes, and sets initial values.

NOTE: This method does not isolate the configuration object by merging/cloning. The caller is responsible for merging/cloning the configuration object if required.

Parameters:

  • 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.

Returns:

Object :

A reference to the host object.

addKey

(
  • value
)

Adds an array to the key hash.

Parameters:

  • value Object

    Indicates what key to use in retrieving the array.

addTarget

(
  • o

fire

(

  • arguments
)
Boolean

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.

Parameters:

  • 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.

Returns:

Boolean :

True if the whole lifecycle of the event went through, false if at any point the event propagation was halted.

readOnly;
writeOnce;
broadcast; and

on

(
  • type
  • fn
  • [context]
  • [arg*]
)
EventHandle

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.

Parameters:

  • type String

    The name of the event

  • fn Function

    The callback to execute in response to the event

  • [context] Object optional

    Override this object in callback

  • [arg*] Any optional

final chainable

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.

Parameters:

  • 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. NOTE: This argument is required if both the boundingBox and contentBox are not currently in the document. If it's not provided, the Widget will be rendered to the body of the current document in this case.

width

Number

Inherited from Widget but overwritten in charts/js/Axis.js:1206

When 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.

Fires event 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.

Parameters:

  • e EventFacade
    An Event Facade object with the following attribute-specific properties added:
    • prevVal Any
      The value of the attribute, prior to it being set.
    • newVal Any
      The value the attribute is to be set to.
    • attrName String
      The name of the attribute being set.
    • subAttrName String
      If setting a property within the attribute's value, the name of the sub-attribute property being set.

Events

destroy

Lifecycle 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).

Event Payload:

init

Lifecycle 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).

Event Payload:

  • e EventFacade

    Event object, with a cfg property which refers to the configuration object passed to the constructor.

render

Lifecycle 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.

Event Payload:

widget:contentUpdate

Notification 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).

Event Payload:
