Method Detail

getModelElement

public static ModelElementInstance getModelElement(DomElement domElement,
                                                   ModelInstanceImpl modelInstance)

Returns the ModelElement for a DOM element. If the model element does not yet exist, it is created and linked to the DOM.

Parameters:

domElement - the child element to create a new ModelElement for

Returns:

the child model element

getQName

public static QName getQName(String namespaceUri,
                             String localName)

ensureInstanceOf

public static void ensureInstanceOf(Object instance,
                                    Class<?> type)

valueAsBoolean

public static boolean valueAsBoolean(String rawValue)

valueAsInteger

public static int valueAsInteger(String rawValue)

valueAsFloat

public static float valueAsFloat(String rawValue)

valueAsDouble

public static double valueAsDouble(String rawValue)

valueAsShort

public static short valueAsShort(String rawValue)

valueAsString

public static String valueAsString(boolean booleanValue)

valueAsString

public static String valueAsString(int integerValue)

valueAsString

public static String valueAsString(float floatValue)

valueAsString

public static String valueAsString(double doubleValue)

valueAsString

getModelElementCollection

public static <T extends ModelElementInstance> Collection<T> getModelElementCollection(Collection<DomElement> view,
                                                                                       ModelInstanceImpl model)

Get a collection of all model element instances in a view

Parameters:

view - the collection of DOM elements to find the model element instances for

model - the model of the elements

Returns:

the collection of model element instances of the view

getIndexOfElementType

public static int getIndexOfElementType(ModelElementInstance modelElement,
                                        List<ModelElementType> childElementTypes)

Find the index of the type of a model element in a list of element types

Parameters:

modelElement - the model element which type is searched for

childElementTypes - the list to search the type

Returns:

the index of the model element type in the list or -1 if it is not found

calculateAllExtendingTypes

public static Collection<ModelElementType> calculateAllExtendingTypes(Model model,
                                                                      Collection<ModelElementType> baseTypes)

Calculate a collection of all extending types for the given base types

Parameters:

baseTypes - the collection of types to calculate the union of all extending types

calculateAllBaseTypes

public static Collection<ModelElementType> calculateAllBaseTypes(ModelElementType type)

Calculate a collection of all base types for the given type

getUniqueIdentifier

public static String getUniqueIdentifier(ModelElementType type)
