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

de.desy.tine.client.TLink.attach()
Attaches the data sets to the created link at the given polling rate and signals the callback routine using a reference to the TLink instance. Asynchronous. This method attaches the data sets to the created link using the calling parameters provided at instantiation. The arriving data will automatically update the output data set and then fire the callback method provided. If the callback is not needed, a null can be passed for this parameter. This is the preferred AttachLink method to use. The Callback instantiates a TLinkCallback() interface which provides a TLink object as parameter. @param mode is the tine control mode parameter, that is one of TMode.CM_POLL, TMode.CM_REFRESH, TMode.SINGLE, etc. in possible combination with TMode.CM_NETWORK or TMode.CM_CONNECT, etc. @param f is the 'callback function' to be called whenever either new data arrive or a change in link status occurs. The callback function should instantiate a class you create which implements the TLinkCallback() class interface. @param pollingInterval is the desired polling rate (at the server) in milliseconds. @param reference is an optional reference to any object of the caller's choosing.As the callback returns a reference to the original link, this extra reference can be used to quickly find a table entry position for example. @return A positive link handle if successful, otherwise -1. On failure the linkStatus property of TLink can be examined. @see de.desy.tine.client.TLink#TLink @see de.desy.tine.client.TLink#TLinkCallback @see de.desy.tine.client.TLink#execute
