IMetadataProvider.NotifyNewTables Method
|
Lightstreamer .Net Adapter 1.7
|
|
|
Called by Lightstreamer Kernel through the Remote Server to check that a User is enabled to add some Tables (i.e. Subscriptions) to a push Session. If the check succeeds, this also notifies the Metadata Adapter that the Tables are being added to the Session.
This method is requested by the Server while holding a lock to the session. This means that any operation on the session, including update dispatching, is blocked during the roundtrip time. Hence, this method should be used only if strictly needed. In general, the WantsTablesNotification method should return false.
void NotifyNewTables(string user, string sessionID, TableInfo [] tables);

Function NotifyNewTables(user As string, sessionID As string, tables As TableInfo []) As void
