ProvaMessengerImpl

public ProvaMessengerImpl(ProvaReagent prova,
                          ProvaKnowledgeBase kb,
                          java.lang.String agent,

Method Detail

prepareMsg

public boolean prepareMsg(ProvaLiteral literal,
                          java.util.List<ProvaLiteral> newLiterals,
                          ProvaRule query)

Prepare a rcvMsg goal for sending on the main agent thread if the verb is 'self' or a thread chosen according to the conversation-id cid (if the verb is 'async' or other). The reactions corresponding to the same conversation-id are thus always run by the same thread.

The message is sent when the next rcvMsg literal is encountered or the whole query is complete.

Specified by:

prepareMsg in interface ProvaMessenger

partitionKey

public static long partitionKey(java.lang.String cid)

sendMsg

public boolean sendMsg(ProvaLiteral literal,
                       java.util.List<ProvaLiteral> newLiterals,
                       ProvaRule query)

Submits asynchronously a rcvMsg goal scheduled on the main agent thread if the verb is 'self' or a thread chosen according to the conversation-id cid (if the verb is 'async' or other). The reactions corresponding to the same conversation-id are thus always run by the same thread.
