Class SnapIfNeededOverlayOp

java.lang.Object

com.revolsys.jts.operation.overlay.snap.SnapIfNeededOverlayOp

public class SnapIfNeededOverlayOp
extends Object

Performs an overlay operation using snapping and enhanced precision to improve the robustness of the result. This class only uses snapping if an error is detected when running the standard JTS overlay code. Errors detected include thrown exceptions (in particular, TopologyException) and invalid overlay computations.
