Interface BytePredicate

All Superinterfaces:
java.util.function.IntPredicate, java.util.function.Predicate<java.lang.Byte>
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 BytePredicate
extends java.util.function.Predicate<java.lang.Byte>, 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 BytePredicate and​(BytePredicate other)
    Returns a composed type-specific predicate that represents a short-circuiting logical AND of this type-specific predicate and another.
    default BytePredicate and​(java.util.function.IntPredicate other)
    default java.util.function.Predicate<java.lang.Byte> and​(java.util.function.Predicate<? super java.lang.Byte> other)
    Deprecated.
    Please use the corresponding type-specific method instead.
    default BytePredicate negate()  
    default BytePredicate or​(BytePredicate other)
    Returns a composed type-specific predicate that represents a short-circuiting logical OR of this type-specific predicate and another.
    default BytePredicate or​(java.util.function.IntPredicate other)
    default java.util.function.Predicate<java.lang.Byte> or​(java.util.function.Predicate<? super java.lang.Byte> other)
    Deprecated.
    Please use the corresponding type-specific method instead.
    boolean test​(byte t)
    Evaluates this predicate on the given input.
    default boolean test​(int t)
    Deprecated.
    Please use the corresponding type-specific method instead.

  • Method Details

    • test

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

    • test

      @Deprecated default boolean test​(int t)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Specified by:
      test in interface java.util.function.IntPredicate

    • test

      @Deprecated default boolean test​(java.lang.Byte t)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Specified by:
      test in interface java.util.function.Predicate<java.lang.Byte>

    • and

      default BytePredicate and​(BytePredicate 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.
      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 BytePredicate and​(java.util.function.IntPredicate other)
      Specified by:
      and in interface java.util.function.IntPredicate
      Implementation Notes:
      Composing with a JDK type-specific predicate will be slightly less efficient than using a type-specific predicate, as the argument will have to be widened at each call.

    • and

      @Deprecated default java.util.function.Predicate<java.lang.Byte> and​(java.util.function.Predicate<? super java.lang.Byte> other)
      Deprecated.
      Please use the corresponding type-specific method instead.
      Specified by:
      and in interface java.util.function.Predicate<java.lang.Byte>

    • negate

      default BytePredicate negate()
      Specified by:
      negate in interface java.util.function.IntPredicate
      Specified by:
      negate in interface java.util.function.Predicate<java.lang.Byte>

    • or

      default BytePredicate or​(BytePredicate 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.

      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).
