AuthenticationPolicy (ActiveMQ 5.17.0 API)

All Known Implementing Classes:

DefaultAuthenticationPolicy
```
public interface AuthenticationPolicy
```
An AuthenticationPolicy customizes the behavior of the AuthenticationFilter, such as whether or not authentication is required or how to represent trusted/known Subject identities.
Most will find customizing properties on the DefaultAuthenticationPolicy easier than implementing this interface directly.

Since:

5.10.0

  - customizeSubject
```
void customizeSubject(org.apache.shiro.subject.Subject.Builder subjectBuilder,
                      ConnectionReference ref)
```
    Allows customization of the Subject being built for the specified client connection. This allows for any pre-existing connection-specific identity or state to be applied to the Subject.Builder before the Subject instance is actually created.
    NOTE: This method is called by the SubjectFilter before the filter chain is executed (and before an authentication attempt occurs). Implementations MUST NOT attempt to actually build the subject or perform an authentication attempt in this method.
    
    Parameters:
    
    subjectBuilder - the builder for the Subject that will be created representing the associated client connection
    
    ref - a reference to the client's connection metadata

  - isAuthenticationRequired
```
boolean isAuthenticationRequired(SubjectConnectionReference ref)
```
    Returns true if the connection's Subject instance should be authenticated, false otherwise.
    
    Parameters:
    
    ref - the subject's connection
    
    Returns:
    
    true if the connection's Subject instance should be authenticated, false otherwise.
