Class RemoteControlServer

java.lang.Object
  edu.rice.cs.drjava.RemoteControlServer

public final class RemoteControlServer
extends Object

This class contains a server that monitors incoming datagrams on port 4444 (default; can be changed in OptionConstants.REMOTE_CONTROL_PORT). These datagrams can contain commands to open additional files. A client can query whether a server is running by sending QUERY_PREFIX. If a server is running, it will respond with RESPONSE_PREFIX. A client can tell a server to open a file by sending QUERY_PREFIX + " " + absoluteFileName. The server will respond with RESPONSE_PREFIX, or RESPONSE_PREFIX + " " + error if an error occurred. A client can tell a server to open a file and jump to a certain line number by sending QUERY_PREFIX + " " + absoluteFileName + File.pathSeparator + lineNumber. The server will respond with RESPONSE_PREFIX, or RESPONSE_PREFIX+" "+error if an error occurred. This class is declared final because it cannot be robustly subclassed because the constructor starts a thread.
