POLS.Core Namespace

Core holds the core base classes used by POLS. Most actual implementations are in other namespaces.

Classes

Class	Description
Beacon	Beacons represent a radio source in the world. They default to not having a position. A mapper can be used to fill in their position.
LatLonCoordinate	A coordinate in latitude and longitude.
LatLonEstimate	An estimation of position in latitude and longitude. A LatLonEstimate is generated by a Tracker
LatLonRectangle	A rectangular area defined by two corners.
Mapper	typically, mappers represent an on-disk (or flash) cache of known beacons that is local to the device. implementations of this interface tend to know how to take a beacon and fill in it's coordinate for a particular application.
MapperException	The exception generated when errors occur within the Mapper
Measurement	Measurements are produced from a Spotter and represent a single scan of the radio environment. They contain zero or more readings, that represent the information about a particular radio source.
Reading	Reading represents the information gained from a scan of the radio environment. This has information about a single beacon in the environment.
Spotter	Provides an interface to environmental sensors, such as GSM radios, that generate Measurement objects. A Measurement will contain a list of Reading objects, whose type will be specific to the Spotter. A Spotter provides both synchronous and asynchronous access methods.
SpotterException	The exception that is thrown when an error occurs when opening, closing, reading from, or generating a measurement for a Spotter.
SpotterExceptionEventArgs	Provides data for SpotterException events.
SpotterMeasurementEventArgs	Provides data for MeasurementAvailable events.
Strings	Centralized storage for various strings that get used throughout the system.
Tracker	Tracker's take in Measurements and produce Estimates. Each tracker encodes a different algorithm about how to compute the estimate.
TrackerEventArgs	TrackerEventArgs contains a LatLonEstimate and the most recent Measurement that contibuted to that position estimate.

Delegates

Delegate	Description
SpotterExceptionEventHandler	Represents the method that will handle ExceptionThrown events.
SpotterMeasurementEventHandler	Represents the method that will handle MeasurementAvailable events.
TrackerEventHandler	TrackerEventHandler delegates handle new Estimates generated by the Tracker
