ProposalConversation

public class Conversation<StateType>
extends AbstractActivity<StateType>

Superclass for conversation activities. The state transitions in a conversation are triggered in two ways: by explicitly calling a method that can "say" something or by receiving a message ("hearing" something) The conversation will always remember the last message that was said or heard as this is supposed to carry all the information that is needed about past messages. This class allows implementors to declaratively set what type of message to except when the conversation is in a given state. If a message is received in a state and there are no defined transitions for that state and the performative of the message, a "do not understand" reply is sent.
