OpenServers Property (IPICollective interface)



OpenServers is a read-only property that returns an OpenServers collection which contains the collective’s member servers that have been opened individually with MemberOpen.  



The object placeholder is an object expression that evaluates to a IPICollective interface, obtained from a Server object.


The servers in this collection are not in the Servers collection.  The Servers collection contains only collective and non-collective PI Servers, not collective member servers as individuals.  In some applications, typically management related, it is necessary to work with a specific member of the collective.  The MemberOpen method is used for this and the OpenServers collection manages member servers opened in this way.  When these member Servers are closed they are removed from this collection.
