SegmentString
public class BasicSegmentString extends java.lang.Object implements SegmentString
Coordinate
s.
Intended to optimize the noding of contiguous segments by
reducing the number of allocated objects.
SegmentStrings can carry a context object, which is useful
for preserving topological or parentage information.
All noded substrings are initialized with the same context object.Constructor | Description |
