Method Summary

All Methods Static Methods Concrete Methods
Modifier and Type	Method and Description
`static <T> Predicate<T>`	`allOf(Predicate<? super T>... components)` Returns a predicate that evaluates to `true` if each of its components evaluates to `true`.
`static <T> Predicate<T>`	`allOf(Predicate<? super T> first, Predicate<? super T> second)` Returns a predicate that evaluates to `true` if both arguments evaluate to `true`.
`static <T> Predicate<T>`	`any()` Returns a predicate that always evaluates to `true`.
`static <T> Predicate<T>`	`anyOf(Predicate<? super T>... components)` Returns a predicate that evaluates to `true` if any one of its components evaluates to `true`.
`static Predicate<UiElement>`	`attributeContains(Attribute attribute, java.lang.String substring)` Returns a predicate that evaluates to `true` on a `UiElement` if its `attribute` contains `substring`.
`static Predicate<UiElement>`	`attributeEquals(Attribute attribute, java.lang.Object expected)` Returns a predicate that evaluates to `true` on a `UiElement` if its `attribute` equals `expected`.
`static Predicate<UiElement>`	`attributeFalse(Attribute attribute)` Returns a predicate that evaluates to `true` on a `UiElement` if its `attribute` is `false`.
`static Predicate<UiElement>`	`attributeMatches(Attribute attribute, java.lang.String regex)` Returns a predicate that evaluates to `true` on a `UiElement` if its `attribute` matches `regex`.
`static Predicate<UiElement>`	`attributeTrue(Attribute attribute)` Returns a predicate that evaluates to `true` on a `UiElement` if its `attribute` is `true`.
`static <T> Predicate<T>`	`not(Predicate<T> predicate)` Returns a predicate that is the negation of the provided `predicate`.
`static Predicate<UiElement>`	`withAncestor(Predicate<? super UiElement> ancestorPredicate)`
`static Predicate<UiElement>`	`withChild(Predicate<? super UiElement> childPredicate)`
`static Predicate<UiElement>`	`withParent(Predicate<? super UiElement> parentPredicate)`
`static Predicate<UiElement>`	`withSibling(Predicate<? super UiElement> siblingPredicate)`

Method Detail

any
```
public static <T> Predicate<T> any()
```
Returns a predicate that always evaluates to true.

not
```
public static <T> Predicate<T> not(Predicate<T> predicate)
```
Returns a predicate that is the negation of the provided predicate.

allOf
```
public static <T> Predicate<T> allOf(Predicate<? super T> first,
                                     Predicate<? super T> second)
```
Returns a predicate that evaluates to true if both arguments evaluate to true. The arguments are evaluated in order, and evaluation will be "short-circuited" as soon as a false predicate is found.

allOf
```
public static <T> Predicate<T> allOf(Predicate<? super T>... components)
```
Returns a predicate that evaluates to true if each of its components evaluates to true. The components are evaluated in order, and evaluation will be "short-circuited" as soon as a false predicate is found.

anyOf
```
public static <T> Predicate<T> anyOf(Predicate<? super T>... components)
```
Returns a predicate that evaluates to true if any one of its components evaluates to true. The components are evaluated in order, and evaluation will be "short-circuited" as soon as a true predicate is found.

attributeTrue
```
public static Predicate<UiElement> attributeTrue(Attribute attribute)
```
Returns a predicate that evaluates to true on a UiElement if its attribute is true.

attributeFalse
```
public static Predicate<UiElement> attributeFalse(Attribute attribute)
```
Returns a predicate that evaluates to true on a UiElement if its attribute is false.

attributeEquals

public static Predicate<UiElement> attributeEquals(Attribute attribute,
                                                   java.lang.Object expected)

Returns a predicate that evaluates to true on a UiElement if its attribute equals expected.

attributeMatches

public static Predicate<UiElement> attributeMatches(Attribute attribute,
                                                    java.lang.String regex)

Returns a predicate that evaluates to true on a UiElement if its attribute matches regex.

attributeContains

public static Predicate<UiElement> attributeContains(Attribute attribute,
                                                     java.lang.String substring)

Returns a predicate that evaluates to true on a UiElement if its attribute contains substring.

withParent

public static Predicate<UiElement> withParent(Predicate<? super UiElement> parentPredicate)

withAncestor

public static Predicate<UiElement> withAncestor(Predicate<? super UiElement> ancestorPredicate)

withSibling

public static Predicate<UiElement> withSibling(Predicate<? super UiElement> siblingPredicate)

withChild

public static Predicate<UiElement> withChild(Predicate<? super UiElement> childPredicate)
