Interface ExToIntFunction<T, E extends Exception>

Type Parameters:
T - the type of the input to the function
E - the type of exception thrown
All Superinterfaces:
Wrappable<ToIntFunction<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 ExToIntFunction<T, E extends Exception> extends Wrappable<ToIntFunction<T>>
Equivalent of a ToIntFunction that can throw exceptions.

  • Method Summary

    Modifier and Type
    Method
    Description
    int
    applyAsInt(T value)
    Applies this function to the given argument.
    default @NonNull ToIntFunction<T>
    wrap()
    Wraps this functional interface, allowing it to be used in contexts where exceptions are not allowed to be thrown directly.

  • Method Details

    • applyAsInt

      int applyAsInt(T value) throws E
      Applies this function to the given argument.
      Parameters:
      value - the function argument
      Returns:
      the function result
      Throws:
      E - potentially

    • wrap

      default @NonNull ToIntFunction<T> wrap()
      Description copied from interface: Wrappable
      Wraps this functional interface, allowing it to be used in contexts where exceptions are not allowed to be thrown directly.

      If a checked exception is thrown, an ExException, which is a runtime exception, will be thrown instead. This will have the original exception as its cause.

      Specified by:
      wrap in interface Wrappable<T>
      Returns:
      a wrapped instance of type W
