Interface ToLongSQLBiFunction<T,U>

Type Parameters:

T - The type of the first argument to the function.

U - The type of the second argument to the function.

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 ToLongSQLBiFunction<T,U>

Represents a function that accepts two arguments and produces a long-valued result. This is the SQLException throwing equivalent of ToLongBiFunction.

Method Summary

Modifier and Type	Method and Description
long	applyAsLong(T t, U u) Applies this function to the given arguments.
static <T,U> ToLongSQLBiFunction<T,U>	checked(ToLongBiFunction<? super T,? super U> function) Returns a function that applies the function function to its input, and unwraps any UncheckedSQLException that is thrown by throwing its cause.
static <T,U> ToLongBiFunction<T,U>	unchecked(ToLongSQLBiFunction<? super T,? super U> function) Returns a function that applies the function function to its input, and wraps any SQLException that is thrown in an UncheckedSQLException.
