Interface Checked.ToIntFunction<T,E extends Throwable>

Type Parameters:
T - Type of the function's parameter.
E - Exception type that can be thrown by the body.
All Superinterfaces:
Checked<ToIntFunction<T>,E>
Enclosing interface:
Checked<WT,EX extends Throwable>
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 static interface Checked.ToIntFunction<T,E extends Throwable> extends Checked<ToIntFunction<T>,E>
Like ToIntFunction but with a body that can throw checked exceptions.
  • Method Details

    • apply

      int apply(T t) throws E
      Applies this function to the given argument.
      Throws:
      E
    • ederWrap

      default ToIntFunction<T> ederWrap()
      Description copied from interface: Checked
      Wraps this Checked functional interfaces as its corresponding Java functional interface WT, which possibly does not allow checked exceptions.

      Checked exceptions of type EX may still, in reality, be thrown. This method is not intended to be called directly; it is used transparently by in(...), which passes the wrapper type into code that requires it, but re-exposes the original checked exception type to the compiler.

      Specified by:
      ederWrap in interface Checked<T,E extends Throwable>
    • use

      static <T, E extends Throwable> Checked.ToIntFunction<T,E> use(Checked.ToIntFunction<T,E> o)
      Shapes a lambda or method reference into an instance of this functional interface.

      This is simply an identity function that can take the place of a more unwieldy cast.

      Type Parameters:
      E - Least upper bound of exception types o can throw.
      Parameters:
      o - The implementing lambda or method reference.
