Public class AbstractFactory
Public class AbstractHandler
Dispatch a (base interface) IGeometry to a more specific handler.

The AbstractHandler base class declares a method abstract void Handler(ISomeGeometryType g) for each geometry interface type ISomeGeometryType

The base class has a complete implementation of the Handler(IGeometry g) method. This method downcasts g to each possible gometry interface and calls the appropriate Handler method.

The NullHandler class (derived from AbstractHandler) has empty (noop) implementations of all known geometry types. Application handlers can derive from NullHandler and selectively override the null implementations.

The DebugHandler class (derived from AbstractHandler) has flags and counters to enable useful debugging services.

Public class AbstractHandler<(Of <(<'TResult, TArgA, TArgB>)>)>
Dispatch a (base interface) IGeometry to a more specific handler.

The AbstractHandler base class declares a method abstract TResult Handle(ISomeGeometryType g, TArgA argA, TArgB, argB) for each geometry interface type ISomeGeometryType

The base class has a complete implementation of the Handle(IGeometry g, arg) method. This method downcasts g to each possible gometry interface and calls the appropriate Dispatcher method.

Public class TransitionSpiral
Concrete base class for TransitionSpiral TransitionSpiral curve described by coordinates, bearing, and radius of tangent circle at start and end. (Radius of 0 indicates a straight line.) The SpiralType is indicated by a string. Interpretation of various types -- Clothoid, Bloth, BiQuadratic -- requires appropriate code in the application. Specialized (e.g. Viennese) types may require furter parameters in auxiliary geometry. A various spiral formulations (clothoid, bloss, sine, cosine, etc) each have a primary interval. The start and end bearing and curvature are at the ends of the nominal interval. The primary interval is placed so its 0 point is at the origin of the placement. However, the actual active portion of the spiral is not required to start or end at the nominal interval. The active interval is specified as fractional coordinates. Fraction 0 is the start of the nominal interval. Fraction 1 is the end of the nominal interval. Spirals used in road and railway transitions will nearly always have the active and nominal intervals the same, i.e. active interval fratctions are 0 and 1. Active interval fractions other than 0 and 1 occur due to trim and extend operations.

(The units of the curvature value are inverse length.) The SpiralType is indicated by a string. Interpretation of various types -- Clothoid, Bloth, BiQuadratic -- requires appropriate code in the application. Specialized (e.g. Viennese) types may require furter parameters in auxiliary geometry.

Public interface ITransitionSpiral
Query methods for TransitionSpiral TransitionSpiral curve described by coordinates, bearing, and radius of tangent circle at start and end. (Radius of 0 indicates a straight line.) The SpiralType is indicated by a string. Interpretation of various types -- Clothoid, Bloth, BiQuadratic -- requires appropriate code in the application. Specialized (e.g. Viennese) types may require furter parameters in auxiliary geometry. A various spiral formulations (clothoid, bloss, sine, cosine, etc) each have a primary interval. The start and end bearing and curvature are at the ends of the nominal interval. The primary interval is placed so its 0 point is at the origin of the placement. However, the actual active portion of the spiral is not required to start or end at the nominal interval. The active interval is specified as fractional coordinates. Fraction 0 is the start of the nominal interval. Fraction 1 is the end of the nominal interval. Spirals used in road and railway transitions will nearly always have the active and nominal intervals the same, i.e. active interval fratctions are 0 and 1. Active interval fractions other than 0 and 1 occur due to trim and extend operations.
