Package ffx.ui

Class FFXExec

java.lang.Object

ffx.ui.FFXExec

All Implemented Interfaces:

Runnable

public class FFXExec
extends Object
implements Runnable

FFXExec encapsulates a native replacement for the JDK System.exec() method. TINKER programs are executed in their own thread through a call to a Native method called "FFXExec" which in turn calls the function "system()". The reason we are not using the System.exec() methods is that some TINKER routines execute indefinitely. Users may want to exit Force Field X and shut down the JVM after launching a dynamics run, for example. In this case the thread should not be dependent on a JVM instance.
