public final class CompoundSelector extends Selector
A compound selector which behaves according to the CSS standard. The selector is composed of one or moreSelectors
, along with an array ofCompoundSelectorRelationships
indicating the required relationship at each stage. There must be exactly one lessCombinator
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:- The component itself is matched by selector3
- The component has an ancestor which is matched by selector2
- The ancestor matched in step 2 is a direct CHILD of a component matched by selector1
selector1 > selector2 selector3
. The greater-than (>) between selector1 and selector2 specifies a direct CHILD, whereas the whitespace between selector2 and selector3 corresponds toCombinator.DESCENDANT

Method Detail
-
getSelectors
public List<SimpleSelector> getSelectors()
The selectors that make up this compound selector- Returns:
- Immutable List<SimpleSelector>
-
createMatch
public Match createMatch()
- Specified by:
createMatch
in classSelector
-
applies
public boolean applies(Styleable styleable, Set<PseudoClass>[] triggerStates, int depth)
-
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 classSelector
- Parameters:
styleable
- the styleablestates
- the state- Returns:
true
if the current state of the node and its parents matches the pseudo-classes defined (if any) for this selector
-
hashCode
public int hashCode()
Description copied from class:Object
Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided byHashMap
.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 inequals
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(Object)
method, then calling thehashCode
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
Object.equals(java.lang.Object)
method, then calling thehashCode
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.
As much as is reasonably practical, the hashCode method defined by class
Object
does return distinct integers for distinct objects. (The hashCode may or may not be implemented as some function of an object's memory address at some point in time.)- Overrides:
hashCode
in classObject
- Returns:
- a hash code value for this object.
- See Also:
Object.equals(java.lang.Object)
,System.identityHashCode(java.lang.Object)
- Whenever it is invoked on the same object more than once during
an execution of a Java application, the
-
equals
public boolean equals(Object obj)
Description copied from class:Object
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 returntrue
. - It is symmetric: for any non-null reference values
x
andy
,x.equals(y)
should returntrue
if and only ify.equals(x)
returnstrue
. - It is transitive: for any non-null reference values
x
,y
, andz
, ifx.equals(y)
returnstrue
andy.equals(z)
returnstrue
, thenx.equals(z)
should returntrue
. - It is consistent: for any non-null reference values
x
andy
, multiple invocations ofx.equals(y)
consistently returntrue
or consistently returnfalse
, provided no information used inequals
comparisons on the objects is modified. - For any non-null reference value
x
,x.equals(null)
should returnfalse
.
The
equals
method for classObject
implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference valuesx
andy
, this method returnstrue
if and only ifx
andy
refer to the same object (x == y
has the valuetrue
).Note that it is generally necessary to override the
hashCode
method whenever this method is overridden, so as to maintain the general contract for thehashCode
method, which states that equal objects must have equal hash codes.- Overrides:
equals
in classObject
- Parameters:
obj
- the reference object with which to compare.- Returns:
true
if this object is the same as the obj argument;false
otherwise.- See Also:
Object.hashCode()
,HashMap
- It is reflexive: for any non-null reference value
-
toString
public String toString()
Description copied from class:Object
Returns a string representation of the object. In general, thetoString
method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.The
toString
method for classObject
returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@
', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:getClass().getName() + '@' + Integer.toHexString(hashCode())

writeBinary

- Overrides:
writeBinary
in classSelector
- Throws:
IOException
