Uses of Class
userDatabase.User

Packages that use User

architectureInterface	Provides all interfaces, given by this mix' software architecture for each component ("NameOfComponent"Interface.java).
inputOutputHandler	InputOutputHandler component - Handles (mix) message-based connections (see package Message) with communication partners (clients, other mixes and proxy servers) and therefore abstracts from the physic communication channels.
message	Provides different message formats, the InputOutputHandler is capable of transmitting.
messageProcessor	MessageProcessor component - Takes messages from component InputOutputHandler, processes them (recoding, checking for replays, removing/adding padding, initiating message authentication) and bypasses them to component OutputStrategy.
userDatabase	User Database component - Used to store user-specific data (for example identifiers, session keys or buffers)
