public ZBrokerSingleThread()

Method Detail

init

public void init(IniFile ini,
                 String serverName)

init should only be called once. It sets some static variables. It is not a static method because static methods cannot be subclassed. init is called through ZBrokerThread and not directly. All ZBrokerThreads must implement an init class.

Parameters:

ini - configuration file

name - section name for this thread

Overrides:

init in class ZBrokerThread

stayConnected

protected boolean stayConnected(boolean anotherCondition)

Decide whether an idle connection should be dropped or should remain open. The boolean passed in overrides any other decision.

processCommand

public void processCommand(DataInputStream dataIn,
                           DataOutputStream dataOut)

Process a request. The request is read from dataIn and is replied to on dataOut. A single TransactionHandler thread is created and re-used for each request.

Parameters:

dataIn - input stream for requests

dataOut - output stream for responses
