Class Summary

Class	Description
ByteBuffer	A byte buffer class.
CoordinateWithinTolerancePointEquality	A PointEquality that considers Points to be equal when their coordinates are within a specified tolerance of each other.
DefaultMeasureGeometryOperations	Default implementation of MeasureGeometryOperations.
EmptyPointSequence	Represents an empty PointSequence.
Envelope	An envelope or bounding box implementation.
ExactCoordinatePointEquality	A PointEquality implementation that considers two Points to be equal if and only if the have the same coordinates.
Geometry	The base class for Geometrys.
GeometryCollection	A Geometry that is an ordered collection of some number of Geometrys.
GeometryFactory	A Factory for Geometrys.
GeometryPointEquality	A GeometryEquality that considers two Geometrys to be equal iff one of these conditions is satisfied: both have the same type, coordinate reference system and consist of the same Points. both are empty
LinearRing	A LineString that is both closed and simple.
LineSegment	A portion of a line delimited (inclusively) by two Points.
LineSegments	Turns a PointSequence into an Iterable over the LineSegments defined by each consecutive pair of Points in the PointSequence.
LineString	A LineString is a 1-dimensional Geometry consisting of the LineSegments defined by consecutive pairs of Points of a PointSequence.
MeasureInterpolatingVisitor	A GeometryVisitor that derives a Geometry by interpolating on the measure values of the visited Geometries.
MultiLineString
MultiPoint
MultiPolygon	A GeometryCollection that contains only Polygons.
Point
PointCollectionFactory	A factory for PointSequences.
PointCollectionPointEquality	A PointCollectionEquality implementation that considers two PointSequences equal if and only if both contain the same points in the same order.
Points	A convenience factory for Points.
PointSequenceBuilders	A factory for PointSequenceBuilders.
PointSequenceIterator	An Iterator over the Points of a PointSequence.
Polygon	A planar surface defined by 1 exterior boundary and 0 or more interior boundaries.
PolyHedralSurface
Vector	A set of utility functions for basic 2D vector functions.

Enum Summary

Enum	Description
ByteOrder	Indicates the byte-order for a ByteBuffer.
CoordinateComponent	Enumerates the components of the coordinates of a point.
