Package org.tinfour.common

Provides classes and interfaces that are common to multiple packages within the TinFour project.

Interface Summary

Interface	Description
IConstraint	Defines the interface for constraints that can be added to instances of the Incremental TIN classes.
IIncrementalTin	Defines the primary methods used by an incremental TIN implementation.
IIncrementalTinNavigator	Provides utilities for performing geometry-based query operations on an incremental tin.
IIntegrityCheck	Defines methods to be used for checking the correctness of code for Incremental TIN implementations.
IMonitorWithCancellation	Provides an interface that allows an process to report its progress to a monitoring application and also permits the implementation of a "voluntary cancellation" action.
INeighborEdgeLocator	Defines methods for a reusable instance of a class for searching a TIN and locating the neighboring edge.
INeighborhoodPointsCollector	Defines an interface for collecting the points in the proximity of a specified pair of coordinates.
IPolyline	An interface for defining a polyline feature (a polygon or chain of connected line segments).
IProcessUsingTin	An interface for classes that perform processing on a TIN.
IQuadEdge	Defines methods for accessing the data in a quad-edge implementation.
ISamplePoint	Defines a sample point interface to be used for spatial data analysis.

Class Summary

Class	Description
BootstrapUtility	A utility for performing the part of the bootstrap operation that is common to both the standard and virtual incremental TIN implementations.
Circumcircle	Provides center coordinates and radius for a circumcircle.
GeometricOperations	Provides elements and methods to support geometric operations using "double double" precision where necessary.
LinearConstraint	An implementation of the IConstraint interface intended to store constraints comprised of a chain of connected line segments.
NearestEdgeResult	Provides a minimal set of data elements for the result of a nearest-edge location operation.
NeighborEdgeVertex	Provides a minimal set of data elements for the result of a neighbor-edge location operation.
PolygonConstraint	An implementation of the IConstraint interface intended to store constraints comprised of a polygon.

SimpleTriangle	Provides methods and elements for a simple representation of a triangle based on IQuadEdge edges.
SimpleTriangleIterator	An implementation of an iterator for looping through the triangles implicit in a Triangulated Irregular Network.
Thresholds	Provides a standard calculation of threshold values appropriate for use in an incremental TIN implementation based on nominal point spacing.
TriangleCount	Provides descriptive data for a Triangulated Irregular Network (TIN).
Vertex	Represents a point in a connected network on a planar surface.
VertexAdjustment	Provides a wrapper class used to represent the adjusted position of a vertex.
VertexIterator	An implementation of an iterator for looping through the vertices that form a Triangulated Irregular Network.
VertexMergerGroup	A synthetic vertex used to handle cases when multiple vertices occupy coincident locations.

Enum Summary

Enum	Description
BootstrapUtility.BootstrapTestResult	Indicates the results of the evaluation for a set of input points.
VertexMergerGroup.ResolutionRule	Specifies a rule for determining a z value based on the collection of coincident vertices.

Exception Summary

Exception	Description
InsufficientConstraintGeometryException	Defines an exception to be thrown in cases where the set of constraints is insufficient to bootstrap a non-bootstrapped) instance of an Incremental TIN.
