int execute(ProcessContext ctx)
     throws java.io.IOException

Synchronously executes the given ProcessContext.

Parameters:

ctx - the context to execute

Returns:

the exit code of the underlying os process.

Throws:

java.io.IOException - on eny error while executing the process.

quit

void quit()
   throws java.io.IOException

Terminates this ProcessExecutor and frees all associated resources. Note the lifecycle of a ProcessExecutor has tenant scope, i.e. there is no need to call quit() except when shutting down the server (what will be done automatically).

Throws:

java.io.IOException - on any error
