Interface DblToObj<R>

Type Parameters:

R - the type of the return value

All Superinterfaces:

DblToObjE<R,RuntimeException>, DoubleFunction<R>

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 DblToObj<R>
extends DblToObjE<R,RuntimeException>, DoubleFunction<R>

An operation of type (double) -> R.

Method Summary

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

Method Detail

unchecked

static <R,E extends Exception> DblToObj<R> unchecked(Function<? super E,RuntimeException> toRuntime,
                                                     DblToObjE<R,E> f)

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

Type Parameters:

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 DblToObjE.call(double), 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 <R,E extends Exception> DblToObj<R> unchecked(DblToObjE<R,E> f)

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

Type Parameters:

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 <R,E extends IOException> DblToObj<R> uncheckedIO(DblToObjE<R,E> f)

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

Type Parameters:

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 <R> NilToObj<R> bind(DblToObj<R> f,
                            double d)

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

Type Parameters:

R - the type of the return value

Parameters:

f - the unbound function

d - the argument

Returns:

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

bind

default NilToObj<R> bind(double d)

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

Specified by:

bind in interface DblToObjE<R,RuntimeException>

Parameters:

d - the argument

Returns:

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

apply

default R apply(double d)

Allows this to act as a DoubleFunction<R>.

Specified by:

apply in interface DoubleFunction<R>

Parameters:

d - the argument

Returns:

the result of the operation
