drawGroupPrimitives abstract method

List<MarkElement<ElementStyle>> drawGroupPrimitives(
  1. List<Attributes> group,
  2. CoordConv coord,
  3. Offset origin
)

Renders primitive elements of all tuples of a group.

The tuples are rendered in groups. the Attributes.shape of the first tuple of a group will be taken as a represent, and it's drawGroupPrimitives method decides the basic way to render the whole group. If different tuples have different shapes, define and call special element rendering methods for each item.

Implementation

List<MarkElement> drawGroupPrimitives(
  List<Attributes> group,
  CoordConv coord,
  Offset origin,
);
