    • 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

    • getModelElement

      public static ModelElementInstance getModelElement(DomElement domElement, ModelInstanceImpl modelInstance, ModelElementTypeImpl modelType)
      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
