Module ushiosan.jvm.utilities

Package ushiosan.jvm.function

Interface UFunErrSafe.UFunErrSafe4<R,T1,T2,T3,T4,E extends Throwable>

Type Parameters:

T1 - first function argument

T2 - second function argument

T3 - third function argument

T4 - fourth function argument

E - execution error

All Superinterfaces:

UFunErr.UFunErr4<R,T1,T2,T3,T4,E>

Enclosing interface:

UFunErrSafe<R,E extends Throwable>

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 static interface UFunErrSafe.UFunErrSafe4<R,T1,T2,T3,T4,E extends Throwable>
extends UFunErr.UFunErr4<R,T1,T2,T3,T4,E>

Representation of a method in Java. Although called a function, it works very similar to a method, and it is possible to reference one via referencing or lambda expressions.
