Interface LockBox.Entry

Enclosing class:
LockBox
public static interface LockBox.Entry
Entry in a LockBox.

Entries are created using LockBox.register(Object).

The object can be retrieved using getValue() if you have the entry, or LockBox.get(String) if you only have the string key.

Holding onto an Entry will prevent the entry, and the associated value from being garbage collected. Holding onto the moniker will not prevent garbage collection.
