getGraphicLayerDataSource

public Iterator getGraphicLayerDataSource()

Provides an iterator to iterate through the data sources stored in this model.

Returns:

An iterator to iterate through the data sources stored in this model.

putDataSource

public void putDataSource(Object key,
                          IlvGraphicLayerDataSource source)

Registers a data source in this model.

Removes the specified data source from the model.

Parameters:

source - The data source to remove.

clearDataSources

public void clearDataSources()

Removes all the data sources from the model.

getAnnotationRoot

public IlvMapLayer getAnnotationRoot(IlvManager pmanager)

Gets or creates the layer used as a parent by the layers created by this toolbar.

Parameters:

pmanager - The manager used to retrieve the layer tree model.

Returns:

The parent of the layers created by the IlvGraphicLayerDatatSource.

getAnnotationRoot

public IlvMapLayer getAnnotationRoot()

Returns the IlvMapLayer used as a parent by the annotations layers when displayed in an IlvLayerTree.

Returns:

The IlvMapLayer used as a parent by the annotations layers.
