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

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

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

getName

public java.lang.String getName()

getUnit

public java.lang.String getUnit()

getValue

public java.lang.Number getValue()

getDoubleValue

public double getDoubleValue()

getRange

public Range getRange()

clone

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

Throws:

java.lang.CloneNotSupportedException

cloneSet
