Interface Summary

Arc	Arc of the circle determined by 3 points, starting at the first, passing through the second and terminating at the third.
ArcByBulge	Equivalents to the Arc, except the bulge representation is maintained.
ArcString	Similar to a line string except that the interpolation is by circular arcs.
ArcStringByBulge	A variant of the arc that stores the parameters of the second constructor of the component arcs and recalculates the other attributes of the standard arc.
Circle	Same as an arc, but closed to form a full circle.
Conic	Any general conic curve.
GenericCurve	Common interface for curve and curve segment.
GenericSurface	Common interface for surface and surface patch.
Geodesic	Two distinct positions joined by a geodesic curve.
GeodesicString	Sequence of geodesic segments.
GeometryFactory	A factory of geometries.
LineSegment	Two distinct direct positions (the start point and end point) joined by a straight line.
LineString	A sequence of line segments, each having a parameterization like the one LineSegment.
ParamForPoint	The curve parameter for a point.
PointArray	A sequence of points.
PointGrid	A grid of points.
Position	A union type consisting of either a direct position or of a reference to a point from which a direct position shall be obtained.

Package org.opengis.spatialschema.geometry.geometry Description

Set of geometric objects. The following is adapted from Feature Geometry (Topic 1) specification.

A geometric object shall be a combination of a coordinate geometry and a coordinate reference system. In all of the operations, all geometric calculations shall be done in the coordinate reference system of the first geometric object accessed, which is normally the object whose operation is being invoked. Returned objects shall be in the coordinate reference system in which the calculations are done unless explicitly stated otherwise. The interface defined in this package are basically those of set theory. In general a geometric object is a set of geometric points, represented by DirectPosition. Object instantiations of geometric objects are Geometry. Object instantiations of geometric points, when used as values, are DirectPositions. General set theory operations defined at Geometry differentiate further down the class hierarchy depending on whether or not the boundary DirectPosition are included as set elements. Subtypes of Primitive do not contain boundary points, while subtypes of Complex do.
