Package nl.vpro.util

Class CommandExecutorImpl

java.lang.Object

nl.vpro.util.CommandExecutorImpl

All Implemented Interfaces:

CommandExecutor

public class CommandExecutorImpl
extends Object
implements CommandExecutor

Wrapper around ProcessorBuilder It makes calling that somewhat simpler and also implements an interface, for easier mocking in test cases. It supports a timeout, for implicit killing the process if it takes too long. It also can wrap stderr to log that as errors.

Since:

1.6
