Interface ThrowablePredicate<T>

Type Parameters:
T - the type of the input to the predicate
All Superinterfaces:
Predicate<T>
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 ThrowablePredicate<T> extends Predicate<T>
Represents a predicate (boolean-valued function) of one argument.

Permits checked exceptions unlike Predicate

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

    • testUnsafe

      boolean testUnsafe(T t) throws Throwable
      Evaluates this predicate on the given argument.
      Parameters:
      t - the input argument
      Returns:
      true if the input argument matches the predicate, otherwise false
      Throws:
      Throwable - occurred during processing

    • test

      default boolean test(T t)
      Evaluates this predicate on the given argument.
      Specified by:
      test in interface Predicate<T>
      Parameters:
      t - the input argument
      Returns:
      true if the input argument matches the predicate, otherwise false

    • isEqual

      static <T> ThrowablePredicate<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)
