Package com.globalmentor.io.function

Interface IOBiFunction<T,U,R>

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

All Known Subinterfaces:

IOBinaryOperator<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 IOBiFunction<T,U,R>

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

This interface is similar to BiFunction except that it is allowed to throw an IOException.

Method Summary

Modifier and Type	Method	Description
default <V> IOBiFunction<T,U,V>	andThen(IOFunction<? super R,? extends V> after)	This method is the same as BiFunction.andThen(java.util.function.Function), but with a support for IOException.
R	apply(T t, U u)	This method is the same as BiFunction.apply(Object, Object), but with a support for IOException.

Method Details

apply

R apply(T t,
 U u)
 throws IOException

This method is the same as BiFunction.apply(Object, Object), but with a support for IOException.

Parameters:

t - The first function.

u - The second function.

Returns:

The function result.

Throws:

IOException - if there is an I/O error performing the operation

andThen

default <V> IOBiFunction<T,U,V> andThen(@Nonnull
 IOFunction<? super R,? extends V> after)
                                 throws IOException

This method is the same as BiFunction.andThen(java.util.function.Function), but with a support for IOException.

Type Parameters:

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

Parameters:

after - The function to be applied after this function.

Returns:

A composed function that applies this function first and then the after function.

Throws:

IOException - if there is an I/O error performing the operation
