Interface IntPredicate

All Superinterfaces:
java.util.function.IntPredicate, java.util.function.Predicate<java.lang.Integer>
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 java.util.function.Predicate<java.lang.Integer>, java.util.function.IntPredicate
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 IntPredicate and​(IntPredicate other)
    Returns a composed type-specific predicate that represents a short-circuiting logical AND of this type-specific predicate and another.
    default IntPredicate and​(java.util.function.IntPredicate other)
    Returns a composed type-specific predicate that represents a short-circuiting logical AND of this type-specific predicate and another.
    default java.util.function.Predicate<java.lang.Integer> and​(java.util.function.Predicate<? super java.lang.Integer> other)
    Deprecated.
    Please use the corresponding type-specific method instead.
    default IntPredicate negate()  
    default IntPredicate or​(IntPredicate other)
    Returns a composed type-specific predicate that represents a short-circuiting logical OR of this type-specific predicate and another.
    default IntPredicate or​(java.util.function.IntPredicate other)
    Returns a composed type-specific predicate that represents a short-circuiting logical OR of this type-specific predicate and another.

    • and

      default IntPredicate and​(java.util.function.IntPredicate other)
      Returns a composed type-specific predicate that represents a short-circuiting logical AND of this type-specific predicate and another.
      Specified by:
      and in interface java.util.function.IntPredicate
      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.
      See Also:
      Predicate.and(java.util.function.Predicate<? super T>)
      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

      default IntPredicate and​(IntPredicate other)
      Returns a composed type-specific predicate that represents a short-circuiting logical AND of this type-specific predicate and another.

      WARNING: Overriding this method is almost always a mistake, as this overload only exists to disambiguate. Instead, override the and() overload that uses the JDK's primitive predicate type (e.g. IntPredicate).

      If Java supported final default methods, this would be one, but sadly it does not.

      If you checked and are overriding the version with java.util.function.XPredicate, and you still see this warning, then your IDE is incorrectly conflating this method with the proper method to override, and you can safely ignore this message.

      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.

    • or

      default IntPredicate or​(java.util.function.IntPredicate other)
      Returns a composed type-specific predicate that represents a short-circuiting logical OR of this type-specific predicate and another.
