javafx.css.Selector

javafx.css.CompoundSelector

public final class CompoundSelector
extends Selector

A compound selector which behaves according to the CSS standard. The selector is composed of one or more Selectors, along with an array of CompoundSelectorRelationships indicating the required relationship at each stage. There must be exactly one less Combinator than there are selectors.

For example, the parameters [selector1, selector2, selector3] and [Combinator.CHILD, Combinator.DESCENDANT] will match a component when all of the following conditions hold:

1. The component itself is matched by selector3
2. The component has an ancestor which is matched by selector2
3. The ancestor matched in step 2 is a direct CHILD of a component matched by selector1

In other words, the compound selector specified above is (in CSS syntax) selector1 > selector2 selector3. The greater-than (>) between selector1 and selector2 specifies a direct CHILD, whereas the whitespace between selector2 and selector3 corresponds to Combinator.DESCENDANT.

Returns:

true if this Selector and a set of PseudoClass applies to the given Styleable

stateMatches

public boolean stateMatches(Styleable styleable,
 Set<PseudoClass> states)

Description copied from class: Selector

Determines whether the current state of the Node and its parents matches the pseudo-classes defined (if any) for this selector.

Specified by:

stateMatches in class Selector

Parameters:

styleable - the styleable

states - the state

Returns:

true if the current state of the node and its parents matches the pseudo-classes defined (if any) for this selector

protected final void writeBinary(DataOutputStream os,
 StyleConverter.StringStore stringStore)
                          throws IOException

Description copied from class: Selector

Writes Selector data in binary form to given DataOutputStream.

Overrides:

writeBinary in class Selector
