Interface ObjToInt<T>

Type Parameters:

T - the type of the argument

All Superinterfaces:

ObjToIntE<T,RuntimeException>, 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 ObjToInt<T>
extends ObjToIntE<T,RuntimeException>, ToIntFunction<T>

An operation of type (T) -> int.

Method Summary

Modifier and Type	Method and Description
default int	applyAsInt(T t) Allows this to act as a ToIntFunction<T>.
static <T> NilToInt	bind(ObjToInt<T> f, T t) Binds (t) to f, returning a new function of type () -> int.
default NilToInt	bind(T t) Binds (t) to this, returning a new function of type () -> int.
static <T,E extends Exception> ObjToInt<T>	unchecked(Function<? super E,RuntimeException> toRuntime, ObjToIntE<T,E> f) Returns a wrapped version of f that uses toRuntime to convert any checked Exception to a RuntimeException.
static <T,E extends Exception> ObjToInt<T>	unchecked(ObjToIntE<T,E> f) Returns a wrapped version of f that wraps any checked Exception with a RuntimeException.
static <T,E extends IOException> ObjToInt<T>	uncheckedIO(ObjToIntE<T,E> f) Returns a wrapped version of f that wraps any IOException with an UncheckedIOException.

Method Detail

unchecked

static <T,E extends Exception> ObjToInt<T> unchecked(Function<? super E,RuntimeException> toRuntime,
                                                     ObjToIntE<T,E> f)

Returns a wrapped version of f that uses toRuntime to convert any checked Exception to a RuntimeException.

Type Parameters:

T - the type of argument 1

E - the Exception type that the operation may throw

Parameters:

toRuntime - if a checked exception is thrown from ObjToIntE.call(T), then this function is called in in order to convert it to a RuntimeException

f - the operation to wrap

Returns:

a wrapped version of f that does not throw checked exceptions

unchecked

static <T,E extends Exception> ObjToInt<T> unchecked(ObjToIntE<T,E> f)

Returns a wrapped version of f that wraps any checked Exception with a RuntimeException.

Type Parameters:

T - the type of argument 1

E - the Exception type that the operation may throw

Parameters:

f - the operation to wrap

Returns:

a wrapped version of f that does not throw checked exceptions

uncheckedIO

static <T,E extends IOException> ObjToInt<T> uncheckedIO(ObjToIntE<T,E> f)

Returns a wrapped version of f that wraps any IOException with an UncheckedIOException.

Type Parameters:

T - the type of argument 1

E - the Exception type that the operation may throw

Parameters:

f - the operation to wrap

Returns:

a wrapped version of f that throws UncheckedIOException instead of IOException

bind

static <T> NilToInt bind(ObjToInt<T> f,
                         T t)

Binds (t) to f, returning a new function of type () -> int.

Type Parameters:

T - the type of the argument

Parameters:

f - the unbound function

t - the argument

Returns:

a new function () -> int that calls f.call(t) and returns the result.

bind

default NilToInt bind(T t)

Binds (t) to this, returning a new function of type () -> int.

Specified by:

bind in interface ObjToIntE<T,RuntimeException>

Parameters:

t - the argument

Returns:

a new function () -> int that calls this.call(t) and returns the result.

applyAsInt

default int applyAsInt(T t)

Allows this to act as a ToIntFunction<T>.

Specified by:

applyAsInt in interface ToIntFunction<T>

Parameters:

t - the argument

Returns:

the result of the operation
