Constructor Detail

AddeServerInfo

public AddeServerInfo()

Creates new AddeServerInfo. This collects information about ADDE server(s) -- their groups, datasets, and date-times (right now only image date-time implemented). This is a helper class for anything else that needs to get these information. The candidate list of ADDE servers should be obtained from a yet-to-be-identified "well-known list", and made available in this class.
