Constructor Details

TLcdSHPModelDescriptor

public TLcdSHPModelDescriptor(String aSourceName,
 String aDisplayName,
 int[] aShapeTypes,
 String[] aFeatureNames,
 Class[] aFeatureClasses)

Constructs a model descriptor for models containing ESRI SHP data.

Parameters:

aSourceName - identifies the source name of the model.

aDisplayName - a display name for the model.

aShapeTypes - the ESRI geometries in the model.

aFeatureNames - the names of the features of the objects in the model.

aFeatureClasses - the classes of the features of the objects in the model.

Method Details

getShapeTypes

public int[] getShapeTypes()

Returns the list geometries that occur in the model.

Returns:

an array of integers that represents the geometries present in the source data.

getContentClassCount

public int getContentClassCount()

Returns the number of distinct classes of objects in the model. 0 if not defined yet.

Specified by:

getContentClassCount in interface ILcdContentDescriptor

Returns:

the number of distinct classes of objects in the model. 0 if not defined yet.

getContentClass

public Class getContentClass(int aIndex)

Returns the class at the given index.

Specified by:

getContentClass in interface ILcdContentDescriptor

Parameters:

aIndex - the index for which the class is requested. This index should be smaller than the return value of getContentClassCount().

Returns:

the class at the given index.

contentContainsClass

public boolean contentContainsClass(Class aClass)

Returns whether the model contains an object of exactly the given class.

Specified by:

contentContainsClass in interface ILcdClassContentDescriptor

Parameters:

aClass - the class to check for.

Returns:

true when the model contains an object of exactly that class, false otherwise.

getDataModel

public TLcdDataModel getDataModel()

Description copied from interface: ILcdDataModelDescriptor

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)).

Specified by:

getDataModel in interface ILcdDataModelDescriptor

Returns:

the data model that describes the elements of the model

getModelElementTypes

public Set<TLcdDataType> getModelElementTypes()

Returns a set containing the single type of which all model elements are instances.

Specified by:

getModelElementTypes in interface ILcdDataModelDescriptor

Returns:

a set containing the single type of which all model elements are instances

getModelTypes

public Set<TLcdDataType> getModelTypes()

Description copied from interface: ILcdDataModelDescriptor

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.

Specified by:

getModelTypes in interface ILcdDataModelDescriptor

Returns:

a set containing all the data types of which instances can be used in the model associated with this descriptor
