com.highqsoft.avalon.MemoryInformation

public class MemoryInformation
extends java.lang.Object

This class collects various memory information about the running avalon process. For retrieving the total memory of the avalon process, under windows the following strategy will be used: - Check if a process exist, that has in the command line the value 'avalon.jar'. - When Avalon was started as windows service, then the service list will parsed for > Name contains the string 'avalon' and no string 'corba' or 'notification'. > The service must have a dependency to other service.
