Interface IntPredicate

All Superinterfaces:
IntPredicate, Predicate<@NotNull Integer>
All Known Subinterfaces:
IntRange
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 IntPredicate extends Predicate<@NotNull Integer>, IntPredicate
Represents a predicate (boolean-valued function) of one argument. This is the primitive type specialization of Predicate for int.

  • Method Details

    • testAsInt

      boolean testAsInt(int value)
      Evaluates this predicate on the given argument.
      Parameters:
      value - the input argument
      Returns:
      true if the input argument matches the predicate or false otherwise

    • test

      default boolean test(int value)
      Specified by:
      test in interface IntPredicate

    • test

      @Contract("null -> fail") default boolean test(@NotNull @NotNull Integer value)
      Specified by:
      test in interface Predicate<@NotNull Integer>

    • and

      @Contract(value="null -> fail; _ -> _", pure=true) @NotNull default @NotNull IntPredicate and(@NonNull @NonNull IntPredicate other)

      Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another. When evaluating the composed predicate, if this predicate is false, then the other predicate is not evaluated.

      Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.

      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
      Throws:
      NullPointerException - if other is null

    • and

      @Contract(value="null -> fail; _ -> _", pure=true) @NotNull default @NotNull IntPredicate and(@NonNull @NonNull Predicate<@NotNull ? super Integer> other)
      Specified by:
      and in interface Predicate<@NotNull Integer>

    • and

      @Contract(value="null -> fail; _ -> _", pure=true) @NotNull default @NotNull IntPredicate and(@NonNull IntPredicate other)
      Specified by:
      and in interface IntPredicate

    • or

      @Contract(value="null -> fail; _ -> _", pure=true) @NotNull default @NotNull IntPredicate or(@NonNull @NonNull IntPredicate other)

      Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another. When evaluating the composed predicate, if this predicate is true, then the other predicate is not evaluated.

      Any exceptions thrown during evaluation of either predicate are relayed to the caller; if evaluation of this predicate throws an exception, the other predicate will not be evaluated.

      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
      Throws:
      NullPointerException - if other is null

    • or

      @Contract(value="null -> fail; _ -> _", pure=true) @NotNull default @NotNull IntPredicate or(@NonNull @NonNull Predicate<@NotNull ? super Integer> other)
      Specified by:
      or in interface Predicate<@NotNull Integer>

    • or

      @Contract(value="null -> fail; _ -> _", pure=true) @NotNull default @NotNull IntPredicate or(@NonNull IntPredicate other)
      Specified by:
      or in interface IntPredicate

    • negate

      @Contract(value="-> _", pure=true) @NotNull default @NotNull IntPredicate negate()
      Specified by:
      negate in interface IntPredicate
      Specified by:
      negate in interface Predicate<@NotNull Integer>

    • isEqual

      @Contract(value="_ -> _", pure=true) @NotNull static @NotNull IntPredicate isEqual(int value)
      Returns a predicate that tests if two arguments are equal.
      Parameters:
      value - value with which to compare the tested one
      Returns:
      a predicate that tests if two arguments are equal

    • isNotEqual

      @Contract(value="_ -> _", pure=true) @NotNull static @NotNull IntPredicate isNotEqual(int value)
      Returns a predicate that tests if two arguments are not equal.
      Parameters:
      value - value with which to compare the tested one
      Returns:
      a predicate that tests if two arguments are not equal

    • alwaysTrue

      @Contract(value="-> _", pure=true) @NotNull static @NotNull DoublePredicate alwaysTrue()
      Creates a predicate which is always true.
      Returns:
      predicate which is always true

    • alwaysFalse

      @Contract(value="-> _", pure=true) @NotNull static @NotNull DoublePredicate alwaysFalse()
      Creates a predicate which is always false.
      Returns:
      predicate which is always false
