The model for the graph. 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 graph bean normally do not need to call any of the methods of this class.

Constructor Detail

GraphModelAdapter

public GraphModelAdapter(Graph graphView)

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.

GraphModelAdapter

public GraphModelAdapter(Graph graphView,
                         DataSource dataSource)

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

Parameters:

graphView - The graph that uses this model.

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

Method Detail

initDefaults

protected void initDefaults(GraphDefaultValues gdv)

Initialize default values from the given GraphDefaultValues 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

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

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

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.

getGraphFormatManager

public GraphFormatManager getGraphFormatManager()

Retrieves the format manager that the graph uses. The graph getFormatManager method calls this method.

Specified by:

getGraphFormatManager in interface GraphModel

Returns:

The format manager of the graph.

setGraphFormatManager

public void setGraphFormatManager(GraphFormatManager m)

Specifies the format manager that the graph uses. The graph setFormatManager method calls this method.

Specified by:

setGraphFormatManager in interface GraphModel

Parameters:

m - The format manager for the graph to use.

getGraphStyleManager

public GraphStyleManager getGraphStyleManager()

Retrieves the style manager that the graph uses. The paging control calls this method.

Specified by:

getGraphStyleManager in interface GraphModel

Returns:

The style manager of the graph.

setGraphStyleManager

public void setGraphStyleManager(GraphStyleManager m)

Specifies the style manager that the graph uses.

Specified by:

setGraphStyleManager in interface GraphModel

Parameters:

m - The style manager for the graph to use.

getGraphView

public Graph getGraphView()

Retrieves the graph that uses this model.

Specified by:

getGraphView in interface GraphModel

Returns:

The graph that uses this model.
