Parameters:

domElement - the child element to create a new ModelElement for

Returns:

the child model element

getModelElement

public static ModelElementInstance getModelElement(DomElement domElement,

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

modelInstance - the ModelInstance for which the new ModelElement is created

modelType - the ModelElementType to create a new ModelElement for

Returns:

the child model element
