      • getName

        public java.lang.String getName()
        Description copied from interface: AuthScheme
        Returns textual designation of the given authentication scheme.
        Specified by:
        getName in interface AuthScheme
        Returns:
        the name of the given authentication scheme
      • isConnectionBased

        public boolean isConnectionBased()
        Description copied from interface: AuthScheme
        Determines if the authentication scheme is expected to provide an authorization response on a per connection basis instead of the standard per request basis
        Specified by:
        isConnectionBased in interface AuthScheme
        Returns:
        true if the scheme is connection based, false if the scheme is request based.
      • getRealm

        public java.lang.String getRealm()
        Description copied from interface: AuthScheme
        Returns authentication realm. If the concept of an authentication realm is not applicable to the given authentication scheme, returns null.
        Specified by:
        getRealm in interface AuthScheme
        Returns:
        the authentication realm
      • processChallenge

        public void processChallenge​(AuthChallenge authChallenge,
                                     org.apache.hc.core5.http.protocol.HttpContext context)
                              throws MalformedChallengeException
        Description copied from interface: AuthScheme
        Processes the given auth challenge. Some authentication schemes may involve multiple challenge-response exchanges. Such schemes must be able to maintain internal state when dealing with sequential challenges
        Specified by:
        processChallenge in interface AuthScheme
        Parameters:
        authChallenge - the auth challenge
        context - HTTP context
        Throws:
        MalformedChallengeException - in case the auth challenge is incomplete, malformed or otherwise invalid.
      • isChallengeComplete

        public boolean isChallengeComplete()
        Description copied from interface: AuthScheme
        Authentication process may involve a series of challenge-response exchanges. This method tests if the authorization process has been fully completed (either successfully or unsuccessfully), that is, all the required authorization challenges have been processed in their entirety.
        Specified by:
        isChallengeComplete in interface AuthScheme
        Returns:
        true if the authentication process has been completed, false otherwise.
      • isResponseReady

        public boolean isResponseReady​(org.apache.hc.core5.http.HttpHost host,
                                       CredentialsProvider credentialsProvider,
                                       org.apache.hc.core5.http.protocol.HttpContext context)
                                throws AuthenticationException
        Description copied from interface: AuthScheme
        Determines whether or not an authorization response can be generated based on the actual authentication state. Generally the outcome of this method will depend upon availability of user credentials necessary to produce an authorization response.
        Specified by:
        isResponseReady in interface AuthScheme
        credentialsProvider - The credentials to be used for authentication
        context - HTTP context
        Returns:
        true if an authorization response can be generated and the authentication handshake can proceed, false otherwise.
        Throws:
        AuthenticationException - if authorization string cannot be generated due to an authentication failure
      • getPrincipal

        public java.security.Principal getPrincipal()
        Description copied from interface: AuthScheme
        Returns Principal whose credentials are used to generate an authentication response. Connection based schemes are required to return a user Principal if authorization applies to for the entire life span of connection.
        Specified by:
        getPrincipal in interface AuthScheme
        Returns:
        user principal
