Method Detail

getScheme

public String getScheme()

Description copied from interface: AuthenticationProvider

The String used to represent this provider. This will correspond to the scheme field of an Id.

Returns:

the scheme of this provider.

handleAuthentication

public KeeperException.Code handleAuthentication(ServerAuthenticationProvider.ServerObjs serverObjs,
                                                 byte[] authData)

Description copied from class: ServerAuthenticationProvider

This method is called when a client passes authentication data for this scheme. The authData is directly from the authentication packet. The implementor may attach new ids to the authInfo field of cnxn or may use cnxn to send packets back to the client.

Specified by:

handleAuthentication in class ServerAuthenticationProvider

Parameters:

serverObjs - cnxn/server/etc that received the authentication information.

authData - the authentication data received.

Returns:

indication of success or failure

matches

public boolean matches(ServerAuthenticationProvider.ServerObjs serverObjs,
                       ServerAuthenticationProvider.MatchValues matchValues)

Description copied from class: ServerAuthenticationProvider

This method is called to see if the given id matches the given id expression in the ACL. This allows schemes to use application specific wild cards.

Specified by:

matches in class ServerAuthenticationProvider

Parameters:

serverObjs - cnxn/server/etc that received the authentication information.

matchValues - values to be matched

isAuthenticated

public boolean isAuthenticated()

Description copied from interface: AuthenticationProvider

This method is used to check if the authentication done by this provider should be used to identify the creator of a node. Some ids such as hosts and ip addresses are rather transient and in general don't really identify a client even though sometimes they do.

Returns:

true if this provider identifies creators.

isValid

public boolean isValid(String id)

Description copied from interface: AuthenticationProvider

Validates the syntax of an id.

Parameters:

id - the id to validate.

Returns:

true if id is well formed.
