Uses of Package
message

Packages that use message

accessControl	Access control component - Supposed to perform authentication, access and admission control.
architectureInterface	Provides all interfaces, given by this mix' software architecture for each component ("NameOfComponent"Interface.java).
client	The Client used to anonymize data (e. g. from a user's application) via a cascade of mixes.
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.
outputStrategy	Output Strategy component - Collects messages until an output criterion is fulfilled (certain number of messages collected or timeout reached)

Classes in message used by accessControl

ChannelEstablishMessage
