getFeaturePropertiesByType

public static List<XSElementDeclaration> getFeaturePropertiesByType(XSModel model,
                                                    QName featureTypeName,
                                                    XSTypeDefinition typeDef)

Produces a list of feature properties where the property value has a type derived from the given (simple or complex) type definition.

Parameters:

model - An XSModel object representing an application schema.

featureTypeName - A qualified feature type name.

typeDef - A (simple or complex) type definition that characterizes the property value domain.

Returns:

A List<XSElementDeclaration> containing matching feature properties; the list may be empty.

getNillableProperties

public static List<XSElementDeclaration> getNillableProperties(XSModel model,
                                               QName featureTypeName)

Produces a list of nillable properties for the specified feature type. The absence of such a property value is explicitly indicated by setting the attribute xsi:nil="true".

Parameters:

model - An XSModel object representing an application schema.

featureTypeName - A qualified feature type name.

Returns:

A List<XSElementDeclaration> containing elements that may have nil values.

getAllFeatureProperties

public static List<XSElementDeclaration> getAllFeatureProperties(XSModel model,
                                                 QName featureTypeName)

Produces a list of all properties for a specified feature type.

Parameters:

model - An XSModel object representing an application schema.

featureTypeName - A qualified feature type name.

Returns:

A List<XSElementDeclaration> containing one or more element declarations defining feature properties.

getSimpleFeatureProperties

public static List<XSElementDeclaration> getSimpleFeatureProperties(XSModel model,
                                                    QName featureTypeName)

Produces a list of properties for a specified feature type that have either (a) a simple type definition or (b) a complex type definition with a simple content model. The standard GML properties are ignored.

Parameters:

model - An XSModel object representing an application schema.

featureTypeName - A qualified feature type name.

Returns:

A List<XSElementDeclaration> containing one or more element declarations defining properties with a simple content model.

getRequiredProperties

public static List<XSElementDeclaration> getRequiredProperties(XSModel model,
                                               QName featureTypeName)

Produces a list of all required properties for a given feature type.

Parameters:

model - An XSModel object representing an application schema.

featureTypeName - A qualified feature type name.

Returns:

A List<XSElementDeclaration> defining zero or more elements which must occur in a valid instance.

removeDeprecatedGMLElements

public static void removeDeprecatedGMLElements(List<XSElementDeclaration> elemDecls,
                               XSModel model)

Removes deprecated GML feature properties from a given list of element declarations. The currently deprecated elements are listed below.

• gml:metaDataProperty
• gml:location

Parameters:

elemDecls - A List of XSElementDeclaration objects.

model - An XSModel object representing a GML application schema.

getBuiltInDatatype

public static QName getBuiltInDatatype(XSElementDeclaration propDecl)

Determines the built-in XML Schema datatype from which the given element declaration is derived. The corresponding type definition may be either a simple type or a complex type with a simple content model.

Parameters:

propDecl - An element declaration (simple content).

Returns:

A QName specifying an XML Schema datatype.
