Represents a selector node in a potential chain of selectors used to match
CSS style declarations to components.
ancestor:CSSSelector
[read-only]
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
If this selector is part of a descendant selector it may have a further
selector defined for an arbitrary ancestor.
Implementation public function get ancestor():CSSSelector
conditions:Array
[read-only]
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
This selector may match a subset of components by specifying further
conditions (for example, a matching component must have a particular id,
styleName (equivalent to a 'class' condition in CSS) or state
(equivalent to a 'pseudo' condition in CSS)).
If no conditions are specified, this property is null.
Implementation public function get conditions():Array
specificity:int
[read-only]
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Calculates the specificity of a selector chain in order to determine
the precedence when applying several matching style declarations. Note
that id conditions contribute 100 points, pseudo and class conditions
each contribute 10 points, types (including descendants in a chain of
selectors) contribute 1 point. Universal selectors (") contribute
nothing. The result is the sum of these contributions. Selectors with a
higher specificity override selectors of lower specificity. If
selectors have equal specificity, the declaration order determines
the precedence (the last one wins).
Implementation public function get specificity():int
subject:String
[read-only]
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
The subject of this selector node (only). To get a String representation
of all conditions and descendants of this selector call the toString()
method.
If this selector represents the root node of a potential chain of
selectors, the subject also represents the subject of the entire selector
expression.
Implementation public function get subject():String
public function CSSSelector(subject:String, conditions:Array = null, ancestor:CSSSelector = null)
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Constructor.
Parameters | subject:String — The plain representation of this selector without
conditions or ancestors. This is typically a fully-qualified class name; for example,
"spark.components.Button". You can use " to match all components or "global" for a global selector.
|
|
| conditions:Array (default = null ) — An optional Array of objects of type CSSCondition that is used to match a
subset of component instances. Currently only a single or a pair of
conditions are supported.
|
|
| ancestor:CSSSelector (default = null ) — An optional selector to match on a component that
descends from an arbitrary ancestor.
|
public function matchesStyleClient(object:IAdvancedStyleClient):Boolean
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Determines whether this selector matches the given component.
Parameters
Returns | Boolean — true if component is a match, or false if not.
|
public function toString():String
Language Version: | ActionScript 3.0 |
Runtime Versions: | Flash Player 10, AIR 1.5 |
Returns a String representation of this selector.
Returns | String — A String representation of this selector including all of its
syntax, conditions and ancestors.
