TaggedLineStringSimplifier class

Constructors

TaggedLineStringSimplifier(LineSegmentIndex inputIndex, LineSegmentIndex outputIndex)

Properties

distanceTolerance ↔ double
getter/setter pair
hashCode → int
The hash code for this object.
no setterinherited
inputIndex ↔ LineSegmentIndex
getter/setter pair
li ↔ LineIntersector
Simplifies a TaggedLineString, preserving topology (in the sense that no new intersections are introduced). Uses the recursive Douglas-Peucker algorithm.

Methods

findFurthestPoint(List<Coordinate> pts, int i, int j, List<double> maxDistance) → int
flatten(int start, int end) → LineSegment
Flattens a section of the line between indexes start and end, replacing them with a line between the endpoints. The input and output indexes are updated to reflect this.
hasBadInputIntersection(TaggedLineString parentLine, List<int> sectionIndex, LineSegment candidateSeg) → bool
hasBadIntersection(TaggedLineString parentLine, List<int> sectionIndex, LineSegment candidateSeg) → bool
hasBadOutputIntersection(LineSegment candidateSeg) → bool
hasInvalidIntersection(LineSegment seg0, LineSegment seg1) → bool
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
remove(TaggedLineString line, int start, int end) → void
Remove the segs in the section of the line @param line @param pts @param sectionStartIndex @param sectionEndIndex
setDistanceTolerance(double distanceTolerance) → void
Sets the distance tolerance for the simplification. All vertices in the simplified geometry will be within this distance of the original geometry.
simplify(TaggedLineString line) → void
Simplifies the given {@link TaggedLineString} using the distance tolerance specified.
simplifySection(int i, int j, int depth) → void
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.

Static Methods

isInLineSection(TaggedLineString line, List<int> sectionIndex, TaggedLineSegment seg) → bool
Tests whether a segment is in a section of a TaggedLineString @param line @param sectionIndex @param seg @return
