All Implemented Interfaces:

XSupplier<T,X>

public class XLazy<T,X extends Exception>
extends Object
implements XSupplier<T,X>

This implementation ensures that the originally defined initialization code is called at most once, even if there is concurrent access from multiple threads, unless the initialization attempt causes an exception.
