Interface ICharPredicate

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 ICharPredicate
Represents a predicate (char-valued function) of one char-valued argument. This is the char-consuming primitive type specialization of Predicate.

This is a functional interface whose functional method is test(char).

  • Method Summary

    Modifier and Type
    Method
    Description
    default ICharPredicate
    and(ICharPredicate aOther)
    Returns a composed predicate that represents a short-circuiting logical AND of this predicate and another.
    default ICharPredicate
    negate()
    Returns a predicate that represents the logical negation of this predicate.
    default ICharPredicate
    or(ICharPredicate aOther)
    Returns a composed predicate that represents a short-circuiting logical OR of this predicate and another.
    boolean
    test(char cValue)
    Evaluates this predicate on the given argument.

  • Method Details

    • test

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

    • negate

      @Nonnull default ICharPredicate negate()
      Returns a predicate that represents the logical negation of this predicate.
      Returns:
      a predicate that represents the logical negation of this predicate

    • and

      @Nonnull default ICharPredicate and(@Nonnull ICharPredicate aOther)
      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:
      aOther - 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

    • or

      @Nonnull default ICharPredicate or(@Nonnull ICharPredicate aOther)
      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:
      aOther - 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
