Description
Class Summary | |
---|---|
Coordinate | A lightweight class used to store coordinates on the 2-dimensional Cartesian plane. |
Coordinate.DimensionalComparator | Compares two Coordinate s, allowing for either a 2-dimensional or
3-dimensional comparison, and handling NaN values correctly. |
CoordinateList | A list of Coordinate s, which may be set to prevent repeated
coordinates from occuring in the list. |
Depth | A Depth object records the topological depth of the sides of an Edge for up to two Geometries. |
Dimension | Constants representing the dimensions of a point, a curve and a surface. |
DirectedEdge | Represents a directed edge in a PlanarGraph . |
DirectedEdgeStar | A DirectedEdgeStar is an ordered list of outgoing DirectedEdges around a node. |
Edge | Represents an undirected edge of a PlanarGraph . |
EdgeEnd | Models the end of an edge incident on a node. |
EdgeEndStar | A EdgeEndStar is an ordered list of EdgeEnds around a node. |
EdgeIntersection | Represents a point on an edge which intersects with another edge. |
EdgeIntersectionList | A list of edge intersections along an Edge . |
EdgeList | A EdgeList is a list of Edges. |
EdgeRing | |
Envelope | Defines a rectangular region of the 2D coordinate plane. |
GeometryGraph | A GeometryGraph is a graph that models a given Geometry |
GraphComponent | A GraphComponent is the parent class for the objects' that form a graph. |
IntersectionMatrix | A Dimensionally Extended Nine-Intersection Model (DE-9IM) matrix. |
Label | A Label indicates the topological relationship of a component
of a topology graph to a given Geometry . |
Location | Constants representing the location of a point relative to a geometry. |
Node | A node in a PlanarGraph is a location where 0 or more Edge s
meet. |
NodeFactory | Factory for creating Node s |
NodeMap | A map of nodes, indexed by the coordinate of the node |
PlanarGraph | The computation of the IntersectionMatrix relies on the use of
a structure called a "topology graph". |
Position | A Position indicates the position of a Location relative to a graph component (Node, Edge, or Area). |
Quadrant | Utility functions for working with quadrants, which are numbered as follows: |
TopologyLocation | A TopologyLocation is the labelling of a GraphComponent's topological relationship to a single Geometry. |
Exception Summary | |
---|---|
TopologyException | Indicates an invalid or inconsistent topological situation encountered during processing |
An implementation of GeoAPI Geometry interfaces from ISO 19107.
