Examples of de.desy.tine.client.TLink.execute()

de.desy.tine.client.TLink.execute()
Executes a synchronous link using the data sets supplied at link creation. Synchronous. This method executes the link using the data sets and parameters provided at instantiation. The call will block for 1000 msec or until the call completes. \note The TLink object created will remain resident until a call to the cancel() method is made. Thus repeated calls to execute() can be made without invoking separate calls to TLink(). @return 0 if successful, otherwise a tine return code which can beinterpreted using getError() or getLastError(). \b Example: \include eg_execute1.java @see de.desy.tine.client.TLink#TLink @see de.desy.tine.client.TLink#attach
