isNull
public boolean isNull()A Depth object is null (has never been initialized) if all depths are null.- Returns:
- True if depth is null (has never been initialized)

public int getDelta(int geomIndex) -
normalize
public void normalize()Normalize the depths for each geometry, if they are non-null. A normalized depth has depth values in the set { 0, 1 }. Normalizing the depths involves reducing the depths by the same amount so that at least one of them is 0. If the remaining value is > 0, it is set to 1. -
