Examples of org.apache.ace.processlauncher.impl.ProcessLauncher

org.apache.ace.processlauncher.impl.ProcessLauncher
Denotes a service that can launch a single process and possibly allows interaction with it.
If for a process multiple instances should be launched, multiple {@link ProcessLauncher}instances should be created!
