- @keyterms:
- process object class, process
- @title:
- process class
- @type:
- class
- @short:
- A class to manage process.
- @inherits:
- [class]object[/class]
- @description:
- The Process class is used to start external programs and to communicate with them.[br]
- !WARNING AT LAST YOU HAVE TO CLOSE THE PROCESS!
- @functions:
- !fn: $addArgument(<process-name:string>)
- With this command you give the process name (or more arguments) for comunication.
- Es: see the next example.
- !fn: $startProcess()
- Tries to run the process.[br]
- Es: [br]
- %process=$new(process);[br]
- %process->$addArg("cmd.exe");[br]
- %process->$start();[br]
- !fn: <string> $readStdout()
- Reads the data that the process has written to standard output.
- !fn: <string> $readStderr()
- Reads the data that the process has written to standard error.

- --------------------End.[br]
- !fn: $writeToStdin(<command:string>)
- Whit this command you send a command to the process:
- !fn: $closekill()
- This tries to terminate the process the nice way.[br]
- If the process is still running after 5 seconds, it terminates the process the hard way.[br]
- (I think that this is the better way.)[br]
- Es:
- %Process->close_kill();
- !fn: $kill()
- Kill the process in hard way.(Bad Idea)
- !fn: $tryTerminate()
- Tries to terminate the process.(It could be well but...)
- !fn: $closeStdin()
- Close the standard Input.
- !fn: <boolean> $isRunning()
- Return 1 if the process is running, else return 0.
- !fn: <boolean> $normalExit()
- Returns TRUE if the process has exited normally; otherwise returns FALSE.
- !fn: $readyReadStdoutEvent()
- This function is invoched by the process when there are new datas.[br]
- The default implementation emits the [classfnc]$readyReadStdout[/classfnc]() signal.
- !fn: $readyReadStderrEvent()
- This function is invoched by the process when there are new error messages.[br]
- The default implementation emits the [classfnc]$readyReadStderr[/classfnc]() signal.
-
- @signals:
- !sg: $readyReadStdout()
- This signal is emitted by the default implementation of [classfnc]$readyReadStdoutEvent[/classfnc]().[br]
- If you reimplement that function you will have to emit the signal manually (if you still need it).
- !sg: $readyReadStderr()
- This signal is emitted by the default implementation of [classfnc]$readyReadStderrEvent[/classfnc]().
