Interface ToLongFunctionWithThrowable<T,E extends Throwable>

Type Parameters:

T - some generic flag

E - The extension

All Superinterfaces:

ToLongFunction<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 ToLongFunctionWithThrowable<T,E extends Throwable>
extends ToLongFunction<T>

Generated from ToLongFunction Extends java.util.function.ToLongFunction to allow for a checked exception.

Method Detail

castToLongFunctionWithThrowable

static <T,E extends Throwable> ToLongFunctionWithThrowable<T,E> castToLongFunctionWithThrowable(ToLongFunctionWithThrowable<T,E> tolongfunctionwiththrowable)

Utility method to mark lambdas of type ToLongFunctionWithThrowable

Type Parameters:

T - Generic that corresponds to the same generic on ToLongFunction

E - The type this interface is allowed to throw

Parameters:

tolongfunctionwiththrowable - The interface instance

Returns:

the cast interface

aToLongFunctionThatUnsafelyThrowsUnchecked

static <T,E extends Throwable> ToLongFunction<T> aToLongFunctionThatUnsafelyThrowsUnchecked(ToLongFunctionWithThrowable<T,E> tolongfunctionwiththrowable)
                                                                                     throws E extends Throwable

Utility method to unwrap lambdas of type ToLongFunction and withUncheckedThrowable any Exception

Type Parameters:

T - Generic that corresponds to the same generic on ToLongFunction

E - The type this interface is allowed to throw

Parameters:

tolongfunctionwiththrowable - The interface instance

Returns:

the cast interface

Throws:

E - the original Exception from tolongfunctionwiththrowable

E extends Throwable

asToLongFunctionWithThrowable

static <T,E extends Throwable> ToLongFunctionWithThrowable<T,E> asToLongFunctionWithThrowable(ToLongFunction<T> tolongfunction)

Utility method to convert ToLongFunctionWithThrowable

Type Parameters:

T - Generic that corresponds to the same generic on ToLongFunction

E - The type this interface is allowed to throw

Parameters:

tolongfunction - The interface instance

Returns:

the cast interface

applyAsLong

default long applyAsLong(T v1)

Overridden method of ToLongFunctionWithThrowable that will call applyAsLongWithThrowable, but catching any exceptions.

Specified by:

applyAsLong in interface ToLongFunction<T>

Parameters:

v1 - parameter to overridden method

Returns:

the value

applyAsLongWithThrowable

long applyAsLongWithThrowable(T v1)
                       throws E extends Throwable

Functional method that will throw exceptions.

Parameters:

v1 - parameter to overridden method

Returns:

the value

Throws:

E - some exception

E extends Throwable

thatReturnsOptional

default Function<T,OptionalLong> thatReturnsOptional()

Returns:

An interface that will wrap the result in an optional, and return an empty optional when an exception occurs.

thatReturnsOnCatch

default ToLongFunction<T> thatReturnsOnCatch(long defaultReturnValue)

Parameters:

defaultReturnValue - A value to return if any throwable is caught.

Returns:

An interface that returns a default value if any exception occurs.

thatUnsafelyThrowsUnchecked

default ToLongFunction<T> thatUnsafelyThrowsUnchecked()
                                               throws E extends Throwable

Returns:

An interface that is only returned if no exception has been thrown.

Throws:

E - if an exception E has been thrown, it is rethrown by this method

E extends Throwable

withLogging
