Package com.mapinfo.midev.geometry

The Geometry package consists of a series of interfaces, classes and enumerations that allow users to work with geometry objects.

See: Description

Interface Summary

Interface	Description
ICurve	An ICurve is an ordered, connected, sequence of ICurveSegment.
ICurveSegment	A ICurveSegment is an ordered sequence of control points and the rule for interpolating a curve along the control points from the first to the last.
IDirectPositionIterator	An iterator that returns copies of IDirectPositions.
IDirectPositionList	A representation of an ordered container of DirectPositions.
IFeatureGeometry	These are the first-class geometric objects that we expect most users of the geometry component to deal in.
IGeometry	Z and M values
ILineString	An ILineString is an ICurveSegment where the control points are connected with straight lines (i.e., linear interpolation between the control points).
IMultiCurve	An unordered container of zero or more ICurves.
IMultiFeatureGeometry	An unordered collection of the IFeatureGeometry types IPoint, IMultiPoint, IMultiCurve and IMultiPolygon.
IMultiPoint	An IFeatureGeometry that is a collection of IPoints all in the same coordinate system.
IMultiPolygon	An IFeatureGeometry that is a collection of IPolygons all in the same coordinate system.
IPoint	An IFeatureGeometry that represents a single point on the earth.
IPolygon	An IPolygon is an IGeometry that consists of a single exterior IRing and zero or more interior IRings that represent holes in the exterior ring.
IPolygonBuilder<T>	A builder for new polygon instances.
IRectangle	An IFeatureGeometry that is an axis aligned rectangle defined by two points (lower left and upper right).
IRing	An IRing is a list of consecutively connected ICurveSegments where the last position is exactly equal to the first position.

Class Summary

Class	Description
CurveBuilder	A builder for creating new ICurve instances.
Envelope	Represents the x and y extents of a geometry.
GeometryFactory	A factory class to create a variety of geometry types through a convenient API.
MultiCurveBuilder	A builder for creating new IMultiCurve instances.
MultiPointBuilder	A builder to create new IMultiPoint instances.
MultiPolygonBuilder	A builder for creating new IMultiPolygon instances.
PolygonRingBuilder<T>	A builder to create outer and inner rings for polygons.
SpatialInfo	All spatial metadata for a geometry.

Enum Summary

Enum	Description
CurveInterpolationType	Identification of the different ways the control points of a curve segment can be connected.
GeometryType	Enumeration of all possible supported geometries.

Exception Summary

Exception	Description
InvalidComputationTypeException	Thrown when a required type of calculation cannot be attempted on a geometry.
InvalidGeometryConversionException	Thrown when a geometry cannot be converted from one geometry type to another geometry type.
InvalidGeometryException	Thrown when a geometry is not valid.
InvalidGeometryOperationException	Thrown when given parameters are not valid to the required operation.
InvalidGeometryTypeException	Thrown when a geometry type is not valid.
UnsupportedGeometryOperationException	Thrown when an unsupported operation is attempted on a geometry.

Package com.mapinfo.midev.geometry Description

The Geometry package consists of a series of interfaces, classes and enumerations that allow users to work with geometry objects.

The interfaces within the Geometry package define the composition aspects for all geometry object types. Provided are interfaces that describe points, lines, polygons, curves, etc. Concrete classes are provided as helper-utility classes for working with geometry objects and enumerations are supplied that define the different "type listings" associated with geometry objects.

The primary interface within this package is interface IGeometry. IGeometry defines the basic behavior of all geometry classes. For example, it defines functionality for returning a geometry object's type, its coordinate system information, and envelope (minimum bounding rectangle).

IGeometry is related to IFeature in the following way. IFeature can return an IFeatureGeometry object. IFeatureGeometry extends IGeometry. At runtime, the IFeatureGeometry object of an IFeature object can be rendered into a map image to visually represent that feature in the map.
