Class Caused

java.lang.Object

io.smallrye.mutiny.helpers.Caused

public class Caused
extends Object

A utility class that creates a predicate on a throwable. If the tested throwable is a runtime exception that has a cause, it unwraps the cause and checks if it is assignable to the cause class provided on predicate creation. It is a companion to the unchecked utilities which wraps checked exceptions into unchecked Runtime exceptions. If the tested throwable has cause, the assignment check will occur on the throwable itself.
