public class DataArrayImpl extends AbstractArrayImpl

Array of identical components. Can be of variable size. In the case of a variable size array, size is actually given by another component: sizeComponent which should be a Count. There are two cases of variable size component: - The component is explicitely listed in the component tree (in this case, the count component has a parent) - The component is implicitely given before the array data (in this case, the count component has no parent) 08-2014: Updated to implement new API autogenerated from XML schema

    • DataArrayImpl

      public DataArrayImpl()
      Default constructor. The array will be variable size with implicit size until either setSize() is called or the elementType property is set to reference the ID of another component in the tree.
