public class TLcdHashedFeaturedModelDescriptor extends TLcdModelDescriptor implementsILcdFeaturedDescriptor, ILcdDataModelDescriptor
ILcdModelDescriptor
that is also an ILcdFeaturedDescriptor. It has a list of
feature names, along with their corresponding classes. Internally, a hashtable is
used to provide an efficient mapping from feature names to feature indices.
All elements of the corresponding model shall be ILcdFeatured
and shall have the same features.
Note that this model descriptor is a specific implementation to be used in the context of AIS. It is not a general purpose implementation that can be used to create a featured descriptor given a data type.

TLcdHashedFeaturedModelDescriptor object.

the source, type and display name.aSourceName - aTypeName - aDisplayName - aModelDescriptor - public TLcdHashedFeaturedModelDescriptor(String aSourceName, String aTypeName, String aDisplayName, TLcdDataType aElementType)
TLcdHashedFeaturedModelDescriptor object. The
aElementType parameter will be used to determine the names and
classes of the features of the model elements.aSourceName - the name of the data sourceaTypeName - the type name of the data sourceaDisplayName - the display name of the data sourceaElementType - the data type of the elements that will be contained in the model
that uses this descriptor.public TLcdDataModel getDataModel()
Returns the data model that describes the elements of the model. Note that not necessarily all data in the model will be of a type of this data model. Very likely, types from the dependencies of the returned data model are used as well.
In case the model accepts objects from multiple data models, an anonymous
data model that depends on all these data models should be returned
(see TLcdDataModelBuilder.createAnonymousDataModel(java.util.Collection)).
getDataModel in interface ILcdDataModelDescriptorpublic Set<TLcdDataType> getModelElementTypes()
TLcdUnknownDataTypes.UNKOWN_TYPE is returned.getModelElementTypes in interface ILcdDataModelDescriptorpublic Set<TLcdDataType> getModelTypes()
Returns a set containing all the types of which instances can be used (including both top-level elements and child objects) in the model associated with this descriptor. Implementations are free to limit the result to only include the types of which there are actually instances in the model; but they are not required to do so.
A simple and correct implementation would be to return
getDataModel().getTypes(). Implementations are encouraged to return a subset of
this set if they can do so without spending an unreasonable amount of resources.
Implementations should return null in case they don't know
which types are present in the model.
