Class ProcessExecutor<T extends Exception>

java.lang.Object

org.opencastproject.util.ProcessExecutor<T>

Deprecated.

use ProcessRunner instead

public class ProcessExecutor<T extends Exception>
extends Object

Helper class to execute processes on the host system and outside of the java vm. Since there are problems with reading stdin, stdout and stderr that need to be taken into account when running on various platforms, this helper class is used to deal with those. A generic Exception should be used to indicate what types of checked exceptions might be thrown from this process.
