Interface SimpleTableListener

Deprecated. The use of this listener is deprecated in favor of the HandyTableListener and the subscribe methods based on it.

public interface SimpleTableListener

A fast, though basic, listener interface, which receives notification of data updates and subscription termination for a table.
Only notifications of changed field values received from the Server are available. Unchanged fields are just reported through the UNCHANGED constant. Specific items and fields are only identified by positional information.

Field Summary

static java.lang.String

UNCHANGED Deprecated. Constant that represents unchanged fields.

Method Summary

void	onRawUpdatesLost(int item, int lostUpdates) Deprecated. Notification of one or more updates that were suppressed in the Server because of internal memory limitations.
void	onSnapshotEnd(int item) Deprecated. Notification that no more snapshot events are coming for an item.
void	onUnsubscrAll() Deprecated. Notification of the unsubscription of all the items in the table.
void	onUpdate(int item, java.lang.String[] values) Deprecated. Notification of an update of the values for an item in the table.

Field Detail

UNCHANGED

static final java.lang.String UNCHANGED

Deprecated.

Constant that represents unchanged fields. Object identity rather than object equality must be tested; a string value of "UNCHANGED" may be a legal value coming from the Data Adapter.

Method Detail

onUpdate

void onUpdate(int item,
              java.lang.String[] values)

Deprecated.

Notification of an update of the values for an item in the table.

Parameters:

item - 1-based index of the item in the Group of items in the table.

values - Array of values received from the Server. The values are reported in the same order as the fields in the Schema of the table. Some values may be null. In case of unchanged values, the UNCHANGED constant is reported.

onRawUpdatesLost

void onRawUpdatesLost(int item,
                      int lostUpdates)

Deprecated.

Notification of one or more updates that were suppressed in the Server because of internal memory limitations. The notification can be sent if the subscription mode is RAW or COMMAND. It can also be sent if the subscription mode is MERGE or DISTINCT and unfiltered dispatching has been requested. In all these cases, an update loss may be unacceptable for the client (in filtered COMMAND mode, this applies to ADD and DELETE events only).

Parameters:

item - 1-based index of the item in the Group of items in the table.

lostUpdates - Number of consecutive lost updates for the item.

onSnapshotEnd

void onSnapshotEnd(int item)

Deprecated.

Notification that no more snapshot events are coming for an item. This notification is always received once, when the item is subscribed in DISTINCT or COMMAND mode and the snapshot is requested.

Parameters:

item - 1-based index of the item in the Group of items in the table.

onUnsubscrAll

void onUnsubscrAll()

Deprecated.

Notification of the unsubscription of all the items in the table. The unsubscription may be subsequent to an unsubscribeTable call or to the closure of the connection. There is no guarantee that this call will not be followed by some further onUpdate call. Such extra calls should be ignored.
