Class Parser

  cz.cuni.pogamut.Parser.Parser

All Implemented Interfaces:

MediatorGBInterface, MediatorParserInterface, TranslateUnrealID2IntID

public class Parser
extends java.lang.Object
implements MediatorParserInterface, MediatorGBInterface, TranslateUnrealID2IntID

Gets messages (String) from GameBot translating them via Yylex into MessageObject, doing DeltaCompression and passing them out. Also may be used to send messages to GB. Is configured by GameBotConnection which must be already connected to GameBot!

Field Summary

private java.util.Queue<MessageObject>	bufferToSend Buffer of messages we have to send to the client ...
private java.util.Set<java.lang.Integer>	currentBatch Current batch of messages from GB.
private java.util.HashMap<java.lang.Integer,MessageObject>	dbInt2Msg Map for storing MessageObjects with hasID() true - ITEMS, NAVS, MOVERS... = basically objects
boolean	dontDiff Should Parser create batches and do diffs?
private GameBotConnection	gb
private java.util.Set<java.lang.Integer>	lastBatch Last batch of messages from GB.
Yylex	lex Lexical engine for recognizing GameBot messages.
private java.util.logging.Logger	log
protected boolean	pushIntoBatch Flag which tells us whether we have to put the message int batch, needed for processing initial nav points / items from the map.
private TranslateUnrealID2IntID	unrealID

Constructor Summary

Parser(GameBotConnection gb, TranslateUnrealID2IntID unrealID, java.util.logging.Logger log)

Method Summary

void	closeGB() Close the connection to the GameBots, if any exists.
void	closeParser() Close the connection to the parser (if any exists).
private MessageObject	diffMessage(MessageObject msg) Creates DELTA MESSAGE out of msg and writes new informations into dbInt2Msg message object
private MessageObject	getMessageFromYylex()
private void	handleEndMessage() Push some messages to bufferToSend if they should be removed from current batch of the client.
MessageObject	receiveParsedMessage() May block.
void	sendMessageToGB(java.lang.String msg) Sends data through GameBotConnection.
