public abstract abstract Coordinate getCoordinate()
Returns:
a coordinate in this component (or null, if there are none)
protected abstract abstract void computeIM(IntersectionMatrix im)
compute the contribution to an IM for this component
public abstract abstract boolean isIsolated()
An isolated component is one that does not intersect or touch any other component. This is the case if the label has valid locations for only a single Geometry.
Returns:
true if this component is isolated
public void updateIM(IntersectionMatrix im)
Update the IM with the contribution for this component. A component only contributes if it has a labelling for both parent geometries
