de.desy.tine.client.TLink
TLink.java User interface calls to access tine data links. The methods presented here deal with linking local application data with remote data sources. Primarily you will need to create a TLink object, passing the necessary identifying parameters of the remote server to which the link is to be established. When the TLink object is instantiated, you will then need to retrieve the data using one of the retrieval methods, e.g. execute() for synchronous acquisition, or attach() for asynchronous acquisition, or receive() for the acquisition of network globals.
