Interface Authorizor

All Known Implementing Classes:

KerberosAuthorizor, ZKAuthorizor

public interface Authorizor

This interface is used for the system which will be used for getting a users Authorizations. If the implementation does not support configuration through Accumulo, it should throw an AccumuloSecurityException with the error code UNSUPPORTED_OPERATION

Method Summary

void	changeAuthorizations(String user, Authorizations authorizations)	Used to change the authorizations for the user
void	dropUser(String user)	Deletes a user
Authorizations	getCachedUserAuthorizations(String user)	Used to get the authorizations for the user
void	initialize(ServerContext context)	Sets up the authorizor for a new instance of Accumulo
void	initializeSecurity(TCredentials credentials, String rootuser)	Used to initialize security for the root user
void	initUser(String user)	Initializes a new user
boolean	isValidAuthorizations(String user, List<ByteBuffer> list)	Used to check if a user has valid auths.
boolean	validSecurityHandlers(Authenticator auth, PermissionHandler pm)	Used to validate that the Authorizor, Authenticator, and permission handler can coexist
