DataSourceValueChanged

public void DataSourceValueChanged(DataSource ds,
                                   long minIndex,
                                   long maxIndex)

Description copied from interface: DataSourceListener

Called when at least a value changed in the data source. The listener shall then get the values in the given range again, if it is interested by the values in that range.

Specified by:

DataSourceValueChanged in interface DataSourceListener

Parameters:

ds - The data source that changed

minIndex - Lower bound of the range where values changed

maxIndex - Higher bound of the range where values changed

DataSourceIndexRangeChanged

public void DataSourceIndexRangeChanged(DataSource ds,
                                        long startIndex,
                                        long lastIndex)

Description copied from interface: DataSourceListener

Called when the range of valid index changed

Specified by:

DataSourceIndexRangeChanged in interface DataSourceListener

Parameters:

ds - The data source that changed

startIndex - The new start Index

lastIndex - The new last index

DataSourceInfoChanged

public void DataSourceInfoChanged(DataSource ds,
                                  DataInfo newInfo)

Description copied from interface: DataSourceListener

Called when the information about the data source changed

Specified by:

DataSourceInfoChanged in interface DataSourceListener

Parameters:

ds - The data source that changed

DataSourceValueRangeChanged

public void DataSourceValueRangeChanged(DataSource ds)

Description copied from interface: DataSourceListener

Called when the range of possible values changed, if defined.

Specified by:

DataSourceValueRangeChanged in interface DataSourceListener

Parameters:

ds - The data source that changed

DataSourceOrderChanged

public void DataSourceOrderChanged(DataSource ds,
                                   int newOrder)

Description copied from interface: DataSourceListener

If defined, called when the order of the source changed. See the sortedOrder() in the Datasource class for more information.

Specified by:

DataSourceOrderChanged in interface DataSourceListener

Parameters:

ds - The data source that changed

DataSourceReplaced

public void DataSourceReplaced(DataSource oldData,
                               DataSource newData)

Description copied from interface: DataSourceListener

Called when a data source is replaced by another one

Specified by:

DataSourceReplaced in interface DataSourceListener

notificationEnd

public void notificationEnd(java.lang.Object referer)

Description copied from interface: EndNotificationListener

This callback is called after all notifications were processed. The referer object is the one to decide what the end means. For example, it may be a single data source notifying both a range change and a value change. Or it could be a collection notifying all its sources.

Specified by:

notificationEnd in interface EndNotificationListener

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Throws:
