Called by the InfoBus each time an InfoBusDataConsumer leaves the InfoBus to alert the DataController of the change. The DataController must remove all references to the consumer from its private lists and ensure that the controller sends no further InfoBusEvents to the consumer.

Specified by:

removeDataConsumer in interface javax.infobus.InfoBusDataController

Parameters:

consumer - - the DataConsumer that is leaving the InfoBus

removeDataProducer

public void removeDataProducer(javax.infobus.InfoBusDataProducer producer)

Called by the InfoBus each time an InfoBusDataProducer leaves the InfoBus to alert the DataController of the change. The DataController must remove all references to the producer from its private lists and ensure that the controller sends no further InfoBusEvents to the producer.

Specified by:

removeDataProducer in interface javax.infobus.InfoBusDataController

Parameters:

producer - - the DataProducer that is leaving the InfoBus

fireItemRevoked

public boolean fireItemRevoked(java.lang.String dataItemName,
                      javax.infobus.InfoBusDataProducer producer)

Called by the InfoBus when a producer requests the distribution of an InfoBusItemRevoked event to consumers on the InfoBus. The DataController decides whether any of the consumers it is managing are potential targets for the Revoked event, and calls one of the two target-specific fireItemRevoked methods on its InfoBus to create and send the event to those consumers.

Note that the DataController should copy the source field it receives to any target-specific method that the controller calls.

Specified by:

fireItemRevoked in interface javax.infobus.InfoBusDataController

Parameters:

dataItemName - the name of the DataItem being revoked by source

producer - the Producer no longer offering the DataItem

Returns:

Stop Code: if true, do not process this request further; if false, continue to next DataController

fireItemAvailable

public boolean fireItemAvailable(java.lang.String dataItemName,
                        java.awt.datatransfer.DataFlavor[] flavors,
                        javax.infobus.InfoBusDataProducer producer)

Called by the InfoBus when the producer "source" requests the distribution of an InfoBusItemAvailable event to consumers on the InfoBus. The DataController decides whether any of the consumers it is managing are potential targets for the Available event, and calls one of the two target-specific fireItemAvailable methods on its InfoBus to create and send the event to those consumers.

Note that the DataController should copy the source field it receives to any target-specific method that the controller calls

Specified by:

fireItemAvailable in interface javax.infobus.InfoBusDataController

Parameters:

dataItemName - the name of the DataItem made available by source

flavors - the DataFlavors the source makes available (optional, possibly null)

source - the Producer offering the DataItem

Returns:

Stop Code: if true, do not process this request further; if false, continue to next DataController

findDataItem

public boolean findDataItem(java.lang.String dataItemName,
                   java.awt.datatransfer.DataFlavor[] flavors,
                   javax.infobus.InfoBusDataConsumer consumer,
                   java.util.Vector foundItem)

Called by the InfoBus when a consumer wishes to find a DataItem matching the given dataItemName. The DataController decides whether any of the producers it is managing are potential sources for the requested data, and issues an InfoBusItemRequestedEvent to them by calling one of the target-specific findDataItem methods on its InfoBus. The first non-null response should be stored in foundItem; the InfoBus only retrieves element 0 from foundItem; any other objects stored there are ignored.

If the DataController returns a DataItem from this method, the InfoBus will stop seeking the data and return that DataItem (calling no other controllers). If foundItem is empty when the call completes, the InfoBus uses the boolean return value to determine whether to continue polling controllers: if true, polling stops and null is returned to the consumer.

Specified by:

findDataItem in interface javax.infobus.InfoBusDataController

Parameters:

dataItemName - the name of the DataItem that the consumer is seeking

flavors - the DataFlavors the consumer prefers (optional, possibly null)

consumer - the Consumer seeking the data

foundItem - a Vector for storing the result which will be empty when the method is called

Returns:

Stop Code: if true, do not process this request further; if false, continue to next DataController. Ignored if foundDataItem is not empty.

findMultipleDataItems

public boolean findMultipleDataItems(java.lang.String dataItemName,
                            java.awt.datatransfer.DataFlavor[] flavors,
                            javax.infobus.InfoBusDataConsumer consumer,
                            java.util.Vector foundItems)

Called by the InfoBus when a consumer wishes to find ALL DataItems matching the given dataItemName. The DataController decides whether any of the producers it is managing are potential sources for the requested data, and issues an InfoBusItemRequestedEvent to each by calling a target-specific findDataItem method on its InfoBus.

All non-null responses should be stored in the foundItems Vector. The responses returned by this controller will be concatenated with those of the controllers called before and after this one. If the return value is true, no further controllers will be polled.

Specified by:

findMultipleDataItems in interface javax.infobus.InfoBusDataController

Parameters:

dataItemName - the name of the DataItem that the consumer is seeking

flavors - the DataFlavors the consumer prefers (optional, possibly null)

consumer - the Consumer seeking the data

foundItems - a Vector for storing all non-null results; will be empty when the method is called

Returns:

Stop Code: if true, do not process this request further; if false, continue to next DataController.

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent ev)

Invoked if a property changed.

Specified by:

propertyChange in interface java.beans.PropertyChangeListener

Overrides:

propertyChange in class FwkPort

Parameters:

ev - The property change event
