Authenticator (Couchbase Java SDK)

All Known Implementing Classes:

CertAuthenticator, ClassicAuthenticator, PasswordAuthenticator
```
@Committed
@Private
public interface Authenticator
```
An Authenticator abstracts credential management for various couchbase operations (all of which fall into one CredentialContext). The interface allows SDK classes to retrieve credentials corresponding to both a context and a specific (wich can be optional for some contexts).

- Method Detail
  - getCredentials
```
List<Credential> getCredentials(CredentialContext context,
                                String specific)
```
    Retrieve the credentials store by this Authenticator for the given CredentialContext and optional specific. If no corresponding credential can be found, an empty list is returned. If the context / specific cannot be processed by this Authenticator, throws an IllegalArgumentException.
    
    Parameters:
    
    context - the context for which the credential(s) will be used.
    
    specific - a more restrictive sub-context specific to the context.
    
    Returns:
    
    a list of credentials that can be used for the context/operation, or empty list if none was set for this context+specific combination.
    
    Throws:
    
    IllegalArgumentException - when the context+specific combination is not supported by an Authenticator implementation.
  - isEmpty
```
boolean isEmpty()
```
    Returns:
    
    true if this Authenticator doesn't have any credentials set.
