Class ScaledNoder

java.lang.Object

com.vividsolutions.jts.noding.ScaledNoder

All Implemented Interfaces:

Noder

public class ScaledNoder
extends java.lang.Object
implements Noder

Wraps a Noder and transforms its input into the integer domain. This is intended for use with Snap-Rounding noders, which typically are only intended to work in the integer domain. Offsets can be provided to increase the number of digits of available precision.

Version:

1.7

Method Detail

isIntegerPrecision

public boolean isIntegerPrecision()

getNodedSubstrings

public java.util.Collection getNodedSubstrings()

Description copied from interface: Noder

Returns a Collection of fully noded SegmentStrings. The SegmentStrings have the same context as their parent.

Specified by:

getNodedSubstrings in interface Noder

Returns:

a Collection of SegmentStrings

computeNodes

public void computeNodes(java.util.Collection inputSegStrings)

Description copied from interface: Noder

Computes the noding for a collection of SegmentStrings. Some Noders may add all these nodes to the input SegmentStrings; others may only add some or none at all.

Specified by:

computeNodes in interface Noder

Parameters:

inputSegStrings - a collection of SegmentStrings to node
