The model for the gauge. In the Model-View-Controller architecture, the model is responsible for handling the data that is displayed in a view. In the full BI Beans set, the DataSource is the "big" model. This model interacts with the DataSource, retrieving data and having the data formatted so that the view can display it.

Users of the gauge bean normally do not need to call any of the methods of this class.

Field Detail

m_gaugeView

protected Gauge m_gaugeView

Constructor Detail

GaugeModelAdapter

public GaugeModelAdapter(Gauge gaugeView)

Constructor that does not specify a DataSource. The graph constructs this object as part of its initialization.

Parameters:

graphView - The graph that uses this model.

GaugeModelAdapter

public GaugeModelAdapter(Gauge gaugeView,
                         DataSource dataSource)

Constructor that specifies a DataSource. The gauge constructs this object as part of its initialization.

Parameters:

gaugeView - The gauge that uses this model.

dataSource - The DataSource that will feed data to the gauge. Do not pass null for this parameter.

Method Detail

initDefaults

protected void initDefaults(GaugeDefaultValues gdv)

Initialize default values from the given GaugeDefaultValues instance.

setDataSource

public void setDataSource(DataSource ds)

Specifies the DataSource.

Specified by:

setDataSource in interface Model

Overrides:

setDataSource in class ModelAdapter

Parameters:

ds - The DataSource that feeds data to the graph.

setSupportedDataLayerFlags

protected void setSupportedDataLayerFlags()

This method overrides the setSupportedDataLayerFlags in ModelAdapter It checks the supported data layers in datasource and set the data layer flags to true or false. If a required data layer is not supported create a TypeNotSupportedException, else if a requested data layer is not supported, log an error message to ErrorHandler

Specified by:

setSupportedDataLayerFlags in class ModelAdapter

getDataMap

@Concealed
public DataMap getDataMap()

Specified by:

getDataMap in class ModelAdapter

Returns:

The DataMap.

For internal use only. Application developers should not use this

Retrieves a DataMap. This method creates a new DataMap for retrieving unformatted data from the DataSource. Called by the superclass.

getMetadataMap

@Concealed
public MetadataMap getMetadataMap(int edge)

Specified by:

getMetadataMap in class ModelAdapter

Parameters:

edge - The edge for which the MetadataMap is needed.

Returns:

The MetadatMap.

For internal use only. Application developers should not use this

Retrieves a MetadataMap. This method creates a new MetadataMap for retrieving metadata values, such as member labels. Called by the superclass.

getLayerMetadataMap

@Concealed
public LayerMetadataMap getLayerMetadataMap(int edge)

Specified by:

getLayerMetadataMap in class ModelAdapter

Parameters:

edge - The edge for which the LayerMetadataMap is needed.

Returns:

The LayerMetadataMap.

For internal use only. Application developers should not use this

Retrieves a LayerMetadataMap. This method creates a new LayerMetadataMap for retrieving metadata values, such as labels. Called by the superclass.

getGaugeView

public Gauge getGaugeView()

Retrieves the gauge that uses this model.

Specified by:

getGaugeView in interface GaugeModel

Returns:

The gauge that uses this model.
