Method Detail

appliesback to summary
public boolean applies(Styleable styleable)

Implements abstract javafx.css.Selector.applies.

Doc from javafx.css.Selector.applies.

Gets whether this Selector applies to the given Styleable.

Parameters
styleable:Styleable

the Styleable to match

Returns:boolean

true if this Selector applies to the given Styleable

Annotations
@Override
appliesback to summary
public boolean applies(Styleable styleable, Set<PseudoClass>[] pseudoClasses, int depth)

Implements abstract javafx.css.Selector.applies.

Doc from javafx.css.Selector.applies.

Gets whether this Selector applies to the given Styleable. It is the same as the applies(Styleable) method except it also returns PseudoClass state that it finds along the way.

Parameters
styleable:Styleable

the Styleable to match

pseudoClasses:Set<PseudoClass>[]

a set of PseudoClass states

depth:int

depth of the Node heirarchy to look for

Returns:boolean

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

Annotations
@Override
createMatchback to summary
public Match createMatch()

Implements abstract javafx.css.Selector.createMatch.

Doc from javafx.css.Selector.createMatch.

Creates a Match.

Returns:Match

a match, never null

Annotations
@Override
equalsback to summary
public boolean equals(Object obj)

Overrides java.lang.Object.equals.

Doc from java.lang.Object.equals.

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

  • It is reflexive: for any non-null reference value x, x.equals(x) should return true.
  • It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
  • It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
  • For any non-null reference value x, x.equals(null) should return false.

An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.

Parameters
obj:Object

the reference object with which to compare.

Returns:boolean

true if this object is the same as the obj argument; false otherwise.

@Override
getIdback to summary
public String getId()

Gets the value of the selector id.

Returns:String

getNameback to summary
public String getName()

Gets the name of the java class to which this selector is applied, or *.

Returns:String

the name of the java class

getNodeOrientationback to summary
public NodeOrientation getNodeOrientation()

Gets the NodeOrientation of this Selector.

Returns:NodeOrientation

the NodeOrientation

getPseudoClassStatesback to summary

getStyleClassesback to summary
public List<String> getStyleClasses()

Gets an immutable list of style-classes of the Selector.

Returns:List<String>

an immutable list of style-classes of the Selector

getStyleClassSetback to summary
public Set<StyleClass> getStyleClassSet()

Gets the immutable Set of StyleClasses of the Selector.

Returns:Set<StyleClass>

the Set of StyleClasses

hashCodeback to summary
public int hashCode()

Overrides java.lang.Object.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object
