AGI.Foundation.Coverage Namespace 
Class  Description  

AssetDataUnavailableException 
Exception thrown when data is unavailable for a given asset in a coverage computation.
 
AssetDefinition 
Defines the 'asset' which can provide coverage and the AccessQuery which can determine whether
or not it provides coverage at a particular time.
 
BaseCoverageDefinition 
The abstract base class for coverage definitions.
 
ContinuousCoverageDefinition  A type of coverage definition that provides a convenient way to organize and initialize a coverage calculation, which computes access calculations over a set of grid points. Each access calculation represents a logical operation determining whether a set of constraints are satisfied for geometry involving one grid point and any number of other assets. For more information, see the Coverage section of the documentation. In contrast to the coverage definitions derived from DiscreteCoverageDefinition, definitions that derive from this class partition the collection of grid points and split these groups amongst available computational cores for calculation.  
CoverageData 
Contains all the information generated by a coverage calculation for a single point. Coverage data for a given point represents
the set of assets which have access to the point at any given time.
 
CoverageDefinitionOnCentralBody  Obsolete. Provides a convenient way to organize and initialize a coverage calculation, which computes access calculations over a set of grid point. Each access calculation represents a logical operation determining whether a set of constraints are satisfied for geometry involving one grid point and any number of other assets. This class uses different threads to loop over a set of grid points. So, after configuring the grid and assets, the grid generation and coverage calculations will automatically divide the grid point calculations between threads unless MultithreadCoverage is set to false or the ThreadingPolicy is configured to use only one thread. As an alternative, consider using DiscreteCoverageDefinitionOnCentralBody, which loops over time instead of looping over the grid and can in some cases provide better performance.  
CoverageDefinitionOnSingleObject 
This coverage definition provides a convenient way to organize and compute a coverage calculation between an object of interest
and an associated group of assets.
 
CoverageFilter 
Filters coverage results based on the number of available assets.
 
CoverageGridPoint  Obsolete.
This class represents a grid point to be used in a coverage calculation. It holds the position
and weighting information and stores the CoverageQueryResult which represents the
results of a coverage calculation for this grid point.
 
CoverageGridPointWithResults 
Represents a coverage grid point that holds the geometrical/statistical CoverageGridPoint (the position, reference frame, weighting, optional central body, and optional grid cell),
and stores the CoverageQueryResult which contains the results of a coverage calculation for this grid point.
 
CoverageGridResult  Obsolete.
This class represents the overall results of a coverage calculation over a grid.
 
CoverageQueryResult 
Contains all the information generated by a coverage calculation for a single grid point.
 
CoverageResults 
This represents the overall results of a coverage calculation over a grid.
 
DiscreteCoverageDefinition  This coverage definition provides a convenient way to organize and initialize a coverage calculation, which computes access calculations over a set of grid points. Each access calculation represents a logical operation determining whether a set of constraints are satisfied for geometry involving one grid point and any number of other assets. For more information, see the Coverage section of the documentation. In contrast to the coverage definitions that inherit from ContinuousCoverageDefinition, which partition the calculation into groups of grid points, this coverage calculation will configure the grid to be evaluated in lockstep in time slices to take advantage of caching redundant calculations common among all grid points. The advantage of this approach is that it can significantly reduce the overall computation time in cases where Earth fixedtoinertial frame calculations, communications network analysis, or other calculations largely independent of any particular grid point are needed. The calculation can also be configured with a larger or smaller timestep to trade off between overall run time and the resolution of the access calculations. If the step size is too small, coverage definitions derived from ContinuousCoverageDefinition may perform better by doing dynamic sampling over time rather than performing a large number of nearlyidentical calculations. However, if the step size is too large, the discrete calculation may miss short intervals that are smaller than the stepsize.  
DiscreteCoverageDefinitionOnCentralBody  Obsolete. Similar to CoverageDefinitionOnCentralBody, this class provides a convenient way to organize and initialize a coverage calculation, which computes access calculations over a set of grid point. Each access calculation represents a logical operation determining whether a set of constraints are satisfied for geometry involving one grid point and any number of other assets. For more information, see the Programmer's GuideOverviewAnalysis section of the documentation. Instead of threading the calculation to loop over grid points, this coverage calculation will configure the grid to be evaluated in lockstep to take advantage of caching redundant calculations common among all grid points. The threads are then configured to loop over intervals of time at a given step size. The advantage of this approach is that it can significantly reduce the overall computation time in cases where Earth fixedtoinertial frame calculations, communications network analysis, or other calculations largely independent of any particular grid point. The calculation can also be configured with a larger or smaller time step to trade off between overall run time and the resolution of the access calculations. If the step size is too small, CoverageDefinitionOnCentralBody may perform better by doing dynamic sampling over time rather than performing a large number of nearlyidentical calculations. However, if the step size is too large, the discrete calculation may miss short intervals that are smaller than the step size.  
MaterializedSpatiallyPartitionedCoverageDefinition 
A coverage definition that uses a delegate to define properties for the grid points. The delegate will be used at runtime to define the properties of the GridPoints.
Once given properties via the delegate these properties persist for the duration of the calculation.
This type of coverage definition splits the coverage calculation up spatially, creating threads to process a group of grid points based upon logical division of available cores or user specified thread count.
 
MaterializedTemporallyPartitionedCoverageDefinition 
A coverage definition that uses a delegate to define properties for the grid points. The delegate will be used at runtime to define the properties of the GridPoints.
Once given properties via the delegate these properties persist for the duration of the calculation.
This coverage definition splits up the coverage calculation into chunks of time.
These chunks of time are specified via the step size parameter in the ComputeCoverageOverTheGrid(JulianDate, JulianDate, Duration) methods.
 
ParameterizedSpatiallyPartitionedCoverageDefinition 
A coverage definition that specifies grid point properties via an archetypical object that provides, at a minimum, an ILocationPointService.
This archetypical object is applied to each grid point at runtime by swapping the object's location with the realized GridPoint defined by the Grid.
This type of coverage definition splits the coverage calculation up spatially, creating threads to process a group of grid points based upon logical division of available cores or user specified thread count.

Delegate  Description  

CoverageGridPointCreationCallback 
A delegate which defines a method for creating a service provider for use in access based on a given
coverage grid point position.
 
CreateCoverageGridPointForAccess  Obsolete.
A delegate which defines a method for creating a service provider for use in access based on a given
coverage grid point position.

Enumeration  Description  

CoverageFilterType 
Indicates whether an interval of coverage is valid based on the number of assets available.
