Declaration

public class PHXProcessInfo
extends java.lang.Object

This class represents information about a running process on the system. It includes static members for listing all processes. This is done in a semi-platform independent way by using an external program which is platform dependent (although fairly consistent on UNIX systems, ps). See PHXRuntime and PHXProcess for other convenient ways to use this information. Note that not all platforms will have all information available.
