Interface ObjToObj<T,R>

Type Parameters:

T - the type of argument 1

R - the type of the return value

All Superinterfaces:

Function<T,R>, ObjToObjE<T,R,RuntimeException>

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 ObjToObj<T,R>
extends ObjToObjE<T,R,RuntimeException>, Function<T,R>

An operation of type (T) -> R.

Method Summary

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

Method Detail

unchecked

static <T,R,E extends Exception> ObjToObj<T,R> unchecked(Function<? super E,RuntimeException> toRuntime,
                                                         ObjToObjE<T,R,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

R - the type of the return value

E - the Exception type that the operation may throw

Parameters:

toRuntime - if a checked exception is thrown from ObjToObjE.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,R,E extends Exception> ObjToObj<T,R> unchecked(ObjToObjE<T,R,E> f)

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

Type Parameters:

T - the type of argument 1

R - the type of the return value

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,R,E extends IOException> ObjToObj<T,R> uncheckedIO(ObjToObjE<T,R,E> f)

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

Type Parameters:

T - the type of argument 1

R - the type of the return value

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,R> NilToObj<R> bind(ObjToObj<T,R> f,
                              T t)

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

Type Parameters:

T - the type of argument 1

R - the type of the return value

Parameters:

f - the unbound function

t - the argument

Returns:

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

bind

default NilToObj<R> bind(T t)

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

Specified by:

bind in interface ObjToObjE<T,R,RuntimeException>

Parameters:

t - the argument

Returns:

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

apply

default R apply(T t)

Allows this to act as a Function<T, R>.

Specified by:

apply in interface Function<T,R>

Parameters:

t - the argument

Returns:

the result of the operation
