Class ProcessRunner

  net.sourceforge.fluxion.spi.utils.ProcessRunner

public class ProcessRunner
extends java.lang.Object

A utility class that simplifies the process of delegating to external processes and waiting for the output. By instantiating a new ProcessRunner and sending it the command you wish to execute in the current runtime environment, calling classes will acquire a string array that contains the lines output by the native process.

java.io.IOException - if the process exited with an error exit code, or there was a problem executing the process
