Class Lazy<T>

java.lang.Object

de.team33.patterns.lazy.e1.Lazy<T>

All Implemented Interfaces:

Supplier<T>

Deprecated.

Further development is discontinued and this package/module may be removed in a future release. Successor edition is the module lazy-narvi.

@Deprecated
public class Lazy<T>
extends Object
implements Supplier<T>

Implements a Supplier that provides a virtually fixed value. This value is only actually determined when it is accessed for the first time.

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 a RuntimeException.

Once the value is established, unnecessary effort to synchronize competing accesses is avoided.
