Reimplemented from JDAQCHSM.

Reimplemented in KM3NETDAQ::DataQueue, and AcousticDataFilter.

Definition at line 606 of file JDAQClient.hh.

If the clock interval is non-zero, the method actionRunning() is repeatedly called when this client machine is in state Running. The file descriptor mask can be set to interrupt the timeout of the select call and clock method wait() in this calling sequence (see methods setSelect() and actionSelect()).

run() [2/3]

void KM3NETDAQ::JDAQClient::run ( const int  port )

inlineinherited

Run for ever.

This method can be used when the run control client is started before the run control (e.g. at boot time of the host processor). This method should be called before the state machine is entered. It launches a server which accepts a JNET::JControlHost connection from a designated application e.g. the JDAQClientStarter.cc program. The state machine is entered using the available data in the JNET::JControlHost message. After the state machine is exited, it accepts a new a JNET::JControlHost connection.

Parameters

port	port number
