Method Detail

getName

QName getName()

Returns the name that features of this type have.

In the GML representation, this corresponds to the feature's element name.

Returns:

the name of the feature instance

getPropertyDeclaration

PropertyType getPropertyDeclaration(QName propName)

Returns the declaration of the property with the given name.

Parameters:

propName - name of the property

Returns:

the declaration of the property, or null if no such property is defined

getPropertyDeclaration

PropertyType getPropertyDeclaration(QName propName,
                                    GMLVersion version)

Returns the declaration of the property with the given name.

Parameters:

propName - name of the property

version - GML version that determines the standard GML properties, must not be null

Returns:

the declaration of the property, or null if no such property is defined

getPropertyDeclarations

List<PropertyType> getPropertyDeclarations()

Returns all property declarations of the feature type, excluding those that any GML feature allows for.

Returns:

property declarations (in order)

getPropertyDeclarations

List<PropertyType> getPropertyDeclarations(GMLVersion version)

Returns all property declarations of the feature type, including those that any GML feature allows for.

Parameters:

version - GML version that determines the standard GML properties, must not be null

Returns:

property declarations (in order)

getDefaultGeometryPropertyDeclaration

GeometryPropertyType getDefaultGeometryPropertyDeclaration()

Returns the first geometry property declaration of the feature type.

Returns:

first geometry property declaration or null if no such declaration exists

isAbstract

boolean isAbstract()

Returns whether this type is abstract or not.

Returns:

true, if this feature type is abstract, false otherwise

newFeature

Feature newFeature(String fid,
                   List<Property> props,
                   ExtraProps extraProps,
                   GMLVersion version)

Creates a new Feature instance (that is of this type).

Parameters:

fid - feature id, or null if the feature doesn't have an id

props - properties

extraProps - properties that are not defined by the FeatureType (e.g. rendering hints)

version - determines the names and types of the standard GML properties, can be null (no GML properties)

Returns:

a new Feature instance

getSchema

AppSchema getSchema()

Returns the AppSchema that this feature type belongs to.

Returns:

the corresponding ApplicationSchema or null if this feature type has none
