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

de.desy.tine.client.TLink.executeAndClose()
Executes a synchronous link using the data sets supplied at link creation and Closes the link upon completion. Synchronous. This method executes the link using the data sets and parameters provided at instantiation. The call will block for the duration of the timeout specified or until the call completes. When the link has completed (successfully or not) the TLink will be automatically closed and hence removed from the link tables, obviating the need for an additional call to closeLink(). @return 0 if successful, otherwise a tine return code which can beinterpreted using getError() or getLastError(). @see de.desy.tine.client.TLink#TLink @see de.desy.tine.client.TLink#attach
