Package nbbrd.io.function

Interface IOPredicate<T>

Type Parameters:
T - the type of the input to the predicate
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 IOPredicate<T>
Represents a predicate (boolean-valued function) of one argument.

  • Method Details

    • testWithIO

      @JdkWithIO boolean testWithIO(T t) throws IOException
      Evaluates this predicate on the given argument.
      Parameters:
      t - the input argument
      Returns:
      true if the input argument matches the predicate, otherwise false
      Throws:
      IOException - if an I/O error occurs

    • and

      @JdkWithIO @NonNull default @NonNull IOPredicate<T> and(@NonNull @NonNull IOPredicate<? super T> 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

    • negate

      @JdkWithIO @NonNull default @NonNull IOPredicate<T> negate()
      Returns a predicate that represents the logical negation of this predicate.
      Returns:
      a predicate that represents the logical negation of this predicate

    • or

      @JdkWithIO @NonNull default @NonNull IOPredicate<T> or(@NonNull @NonNull IOPredicate<? super T> 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

    • asUnchecked

      @NonNull default @NonNull Predicate<T> asUnchecked()

    • unchecked

      @NonNull static <T> @NonNull Predicate<T> unchecked(@NonNull @NonNull IOPredicate<T> o)

    • checked

      @NonNull static <T> @NonNull IOPredicate<T> checked(@NonNull @NonNull Predicate<T> predicate)

    • isEqual

      @JdkWithIO @NonNull static <T> @NonNull IOPredicate<T> isEqual(Object targetRef)
      Returns a predicate that tests if two arguments are equal according to Objects.equals(Object, Object).
      Type Parameters:
      T - the type of arguments to the predicate
      Parameters:
      targetRef - the object reference with which to compare for equality, which may be null
      Returns:
      a predicate that tests if two arguments are equal according to Objects.equals(Object, Object)
