Classes

	Class	Description
	AccessQueryReplacementCopyContext	Copies an AccessQuery while replacing all references of a specified instance with a new specified instance.
	AverageSubCalculationProgress	An implementation of ITrackCalculationProgress that averages the progress of a number of sub-calculations and reports the result to another ITrackCalculationProgress instance. The return value of ForSubCalculation(Double) should be passed to each sub-calculation.
	CachingEvaluator<T>	A wrapper for any IEvaluator<T> that caches the last evaluated result. This way, if a second evaluation is requested for the same date, the value is returned without recomputing it. This class is intended to be returned by GetCachingWrapper().
	CachingMotionEvaluator<T>	A wrapper for any MotionEvaluator<T> that caches the last evaluated result. This way, if a second evaluation is requested for the same date, the value is returned without recomputing it. This class is intended to be returned by GetCachingWrapper().
	CalculationContext	The context in which calculations are performed. This holds a number of facets which describe the problem. Facets can include things like central bodies and leap seconds. To use a facet, call the facet's static method that returns the context. Avoid calling GetFacet(Int32) directly.
	CalculationContextFacet	A facet of a CalculationContext.
	ChildrenExtension	An ObjectExtension which can provide a list of children for a given ExtensibleObject. These children can either be separate objects which are related to the parent or subcomponents which provide completely separate sets of services in conjunction with the parent. For example, a spacecraft (parent) may have several sensors (children) which are each located and pointed separately with respect to the spacecraft.
	CollectionAlgorithms	Contains algorithms that operate on collections.
	ConstantAuthorizationProvider	An authorization provider which stores a constant authorization token which will be used for all resources.
	ConstantParameterizedEvaluator1<TParameter1, TResult>	An evaluator that takes a JulianDate and one additional parameter and produces a constant return value of a given type, ignoring all parameters.
	ConstantParameterizedEvaluator2<TParameter1, TParameter2, TResult>	An evaluator that takes a JulianDate and two additional parameters and produces a constant return value of a given type, ignoring all parameters.
	ConstantParameterizedEvaluator3<TParameter1, TParameter2, TParameter3, TResult>	An evaluator that takes a JulianDate and three additional parameters and produces a constant return value of a given type, ignoring all parameters.
	ConstantParameterizedEvaluator4<TParameter1, TParameter2, TParameter3, TParameter4, TResult>	An evaluator that takes a JulianDate and four additional parameters and produces a constant return value of a given type, ignoring all parameters.
	ConstantParameterizedEvaluator5<TParameter1, TParameter2, TParameter3, TParameter4, TParameter5, TResult>	An evaluator that takes a JulianDate and five additional parameters and produces a constant return value of a given type, ignoring all parameters.
	ConstantParameterizedEvaluator6<TParameter1, TParameter2, TParameter3, TParameter4, TParameter5, TParameter6, TResult>	An evaluator that takes a JulianDate and six additional parameters and produces a constant return value of a given type, ignoring all parameters.

	ConstantValueDefinition<T>	Defines a constant value used in a broader computation. This object produces a ValueEvaluator<T> which by definition cannot vary with time.
	CopyContext	A context that identifies a complete copy operation. It is used to map old references to new references when doing a deep copy of a hierarchy of objects.
	CopyForAnotherThread	Enables copying of IThreadAware objects for use in another thread.
	DefinitionalObject	The base class for all definitional objects. A definitional object has a few characteristics: It can be made read-only by calling the Freeze() method. Attempts to modify a frozen object will result in an ObjectFrozenException. It can be copied to a user-controllable depth using the Clone(CopyContext) method. It can be compared to another definitional object to determine if both are defined equivalently by calling the IsSameDefinition(Object) method. Definitional objects also have a hash code based on their definition that can be retrieved by calling GetDefinitionHashCode(). This hash code is guaranteed not to change during the lifetime of the object, even if properties of the object change. As a result, not all equivalent objects will have the same hash code, but objects that are created in the same way will have the same hash code. This is useful in many situations, and is better than the alternative of allowing an object to get lost in a dictionary when its hash code changes. It can safely be used from multiple threads simultaneously as long as none of the threads are making modifications to the object.
	DefinitionalObjectCollection<T>	A collection of DefinitionalObject objects.
	DependencyEnumerator	Enumerates the dependencies of an object.
	EndianBitConverter	BitConverter assumes that the byte arrays given to it are always in the system's native byte order. If you want to convert bytes that come from a file that is always in the same byte order regardless of the system's endianness, this class will do the byte reordering for you.
	EvaluatorHelper	A collection of methods that are helpful when writing evaluators.
	ExtensibleObject	An object that can be extended at run-time with various ObjectExtension instances in order to add additional properties and behaviors.
	ExtensibleObjectCollection	A collection of instances that implement ExtensibleObject.
	ExtensionCollection	A collection of extensions to an ExtensibleObject.
	FileStreamFactory	A factory that can produce FileStream instances on demand. This type is used by classes that need to work with data from a stream from multiple threads simultaneously. They can use it to open the stream in each thread.
	FormatConverter<T, TFormatType>	Converts between different formats of a given type, where a format is specified as an indexed format object. This class can chain conversions in cases where a direct conversion is not possible.
	GeospatialContentServerAuthorizationProvider	An authorization provider which obtains an authorization token for a given Geospatial Content Server (GCS) application token.
	HashCode	Contains static methods for working with hash codes.
	HierarchicalLogger	A simple hierarchical logging mechanism. Multiple sub-tasks (indicated by a call to Push()) can log simultaneously from different threads and the output will be serialized in the log file.
	IdentifierExtension	An extension that defines a unique identifier for an object.
	ObjectExtension	The base class for extensions that can be added at run-time to ExtensibleObject instances in order to give them additional properties and behaviors.
	ParameterEvaluator<T>	A placeholder for a parameter in an evaluator. Rather than computing something itself, this parameter evaluator allows the evaluator's parameter to be specified externally.
