Class RunCommand

java.lang.Object

org.qbroker.common.RunCommand

All Implemented Interfaces:

java.lang.Runnable

public class RunCommand
extends java.lang.Object
implements java.lang.Runnable

RunCommand runs a given command with timeout constrains. The static method, exec(), returns the stdout of the command if it is successful before it is timed out. Otherwise, exec() throws TimeoutException for timeout or RuntimeException for errors.

RunCommand parses the cmdLine into a cmdArray before execute it. Therefore, you can use double-quotes in the commandLine.
