Interface ToLongBiFunctionWithThrowable<T,U,E extends Throwable>

Type Parameters:

T - some generic flag

U - some generic flag

E - The extension

All Superinterfaces:

ToLongBiFunction<T,U>

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 ToLongBiFunctionWithThrowable<T,U,E extends Throwable>
extends ToLongBiFunction<T,U>

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

Method Detail

castToLongBiFunctionWithThrowable

static <T,U,E extends Throwable> ToLongBiFunctionWithThrowable<T,U,E> castToLongBiFunctionWithThrowable(ToLongBiFunctionWithThrowable<T,U,E> tolongbifunctionwiththrowable)

Utility method to mark lambdas of type ToLongBiFunctionWithThrowable

Type Parameters:

E - The type this interface is allowed to throw

Parameters:

tolongbifunctionwiththrowable - The interface instance

Returns:

the cast interface

aToLongBiFunctionThatUnsafelyThrowsUnchecked

applyAsLong

default long applyAsLong(T v1,
                         U v2)

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

Specified by:

applyAsLong in interface ToLongBiFunction<T,U>

Parameters:

v1 - parameter to overridden method

v2 - parameter to overridden method

Returns:

the value

applyAsLongWithThrowable

long applyAsLongWithThrowable(T v1,
                              U v2)
                       throws E extends Throwable

Functional method that will throw exceptions.

Parameters:

v1 - parameter to overridden method

v2 - parameter to overridden method

E extends Throwable

thatReturnsOptional

default BiFunction<T,U,OptionalLong> thatReturnsOptional()

Returns:

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

thatReturnsOnCatch

default ToLongBiFunction<T,U> 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.
