All Implemented Interfaces:

Iterable<Credential>, CredentialSource

public abstract class IdentityCredentials
extends Object
implements Iterable<Credential>, CredentialSource

The public or private credentials retained by an identity, which can be used for authentication forwarding. This credentials set can contain zero or one credential of a given type and algorithm name. If the credential type does not support algorithm names, then the set can contain zero or one credential of that type. The credential set may be iterated; iteration order is not prescribed and may change if the implementation is changed.
