Interface BooleanPredicate

All Superinterfaces:
Predicate<Boolean>
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface BooleanPredicate extends Predicate<Boolean>
A type-specific Predicate; provides methods to test a primitive type both as object and as primitive.

Except for the boolean case, this interface extends both a parameterized Predicate and a type-specific JDK predicate (e.g., IntPredicate). For types missing a type-specific JDK predicate (e.g., short or float), we extend the predicate associated with the smallest primitive type that can represent the current type (e.g., int or double, respectively).

Since:
8.5.0

  • Method Summary

    Modifier and Type
    Method
    Description
    default BooleanPredicate
    and(BooleanPredicate other)
    Returns a composed type-specific predicate that represents a short-circuiting logical AND of this type-specific predicate and another.
    default Predicate<Boolean>
    and(Predicate<? super Boolean> other)
    Deprecated.
    Please use the corresponding type-specific method instead.
    static BooleanPredicate
    identity()
    Returns a BooleanPredicate that returns the boolean to be tested unmodified.
    default BooleanPredicate
    negate()
     
    static BooleanPredicate
    negation()
    Returns a BooleanPredicate that returns the negation of the boolean to be tested.
    default BooleanPredicate
    or(BooleanPredicate other)
    Returns a composed type-specific predicate that represents a short-circuiting logical OR of this type-specific predicate and another.
    default Predicate<Boolean>
    or(Predicate<? super Boolean> other)
    Deprecated.
    Please use the corresponding type-specific method instead.
    boolean
    test(boolean t)
    Evaluates this predicate on the given input.
    default boolean
    test(Boolean t)
    Deprecated.
    Please use the corresponding type-specific method instead.

  • Method Details

    • test

      boolean test(boolean t)
      Evaluates this predicate on the given input.
      Parameters:
      t - the input.
      Returns:
      true if the input matches the predicate, otherwise false

    • identity

      static BooleanPredicate identity()
      Returns a BooleanPredicate that returns the boolean to be tested unmodified.
      See Also:

    • negation

      static BooleanPredicate negation()
      Returns a BooleanPredicate that returns the negation of the boolean to be tested.

    • test

      @Deprecated default boolean test(Boolean t)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Specified by:
      test in interface Predicate<Boolean>

    • and

      default BooleanPredicate and(BooleanPredicate other)
      Returns a composed type-specific predicate that represents a short-circuiting logical AND of this type-specific predicate and another.
      Parameters:
      other - a predicate that will be logically-ANDed with this predicate.
      Returns:
      a composed predicate that represents the short-circuiting logical AND of this predicate and the other predicate.

      API Notes:
      Implementing classes should generally override this method and keep the default implementation of the other overloads, which will delegate to this method (after proper conversions).

    • and

      @Deprecated default Predicate<Boolean> and(Predicate<? super Boolean> other)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Specified by:
      and in interface Predicate<Boolean>

    • negate

      default BooleanPredicate negate()
      Specified by:
      negate in interface Predicate<Boolean>

    • or

      default BooleanPredicate or(BooleanPredicate other)
      Returns a composed type-specific predicate that represents a short-circuiting logical OR of this type-specific predicate and another.
      Parameters:
      other - a predicate that will be logically-ORed with this predicate.
      Returns:
      a composed predicate that represents the short-circuiting logical OR of this predicate and the other predicate.
