Cumulative Selections

To create a cumulative selection tagged <seltag>, use

model.geom(<tag>).selection().create(<seltag>,"CumulativeSelection");

To make a geometry feature contribute its selection to a cumulative selection, use

model.geom(<tag>).feature(<ftag>).set("contributeto",<seltag>);

To remove the contribution of a geometry feature to a cumulative selection, use

model.geom(<tag>).feature(<ftag>).set("contributeto","none");

To control whether the cumulative selection is available outside the geometry sequence, use

model.geom(<tag>).selection(<seltag>).show(<boolean>);

To query whether the cumulative selection is available outside the geometry sequence, use

boolean show = model.geom(<tag>).selection(<seltag>).show();
