Interface BiFunctionEx<T,U,R,E extends java.lang.Throwable>

Type Parameters:

T - the type of the first argument to the function

U - the type of the second argument to the function

R - the type of the result of the function

E - the type of exception could be thrown while performing operation

All Known Subinterfaces:

BinaryOperatorEx<T,E>

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 BiFunctionEx<T,U,R,E extends java.lang.Throwable>

Represents a function that accepts two arguments and produces a result. This is the two-arity specialization of FunctionEx.

This is a functional interface whose functional method is apply(Object, Object).

Since:

1.8

Method Detail

apply

R apply(T t,
        U u)
 throws E extends java.lang.Throwable

Applies this function to the given arguments.

Parameters:

t - the first function argument

u - the second function argument

Returns:

the function result

Throws:

E extends java.lang.Throwable

andThen

default <V> BiFunctionEx<T,U,V,E> andThen(FunctionEx<? super R,? extends V,E> after)

Returns a composed function that first applies this function to its input, and then applies the after function to the result. If evaluation of either function throws an exception, it is relayed to the caller of the composed function.

Type Parameters:

V - the type of output of the after function, and of the composed function

Parameters:

after - the function to apply after this function is applied

Returns:

a composed function that first applies this function and then applies the after function

Throws:

java.lang.NullPointerException - if after is null

fixRight

default FunctionEx<T,R,E> fixRight(U u)

Build and return FunctionEx interface obtained from the bi-function by fixing second parameter with specified constant value.

Parameters:

u - constant value for fixing second parameter

Returns:

reduced bi-function by fixing second parameter

fixLeft

default FunctionEx<U,R,E> fixLeft(T t)

Build and return FunctionEx interface obtained from the bi-function by fixing first parameter with specified constant value.

Parameters:

t - constant value for fixing first parameter

Returns:

reduced bi-function by fixing first parameter

                            U u)
