Interface KeyLocator

All Superinterfaces:
Iterable<Key>
All Known Implementing Classes:
CompositeKeyLocator, HardcodedKeyLocator
public interface KeyLocator extends Iterable<Key>
This interface defines a method for obtaining a security key by ID.

If the KeyLocator implementor wants to make all its keys available for iteration, it should implement Iterable<T extends Key> interface. The base KeyLocator does not extend this interface to enable KeyLocators that do not support listing their keys.
