Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Returns a String that represents this instance. (Overrides ObjectToString.)
	TryGetPart	Tries the get part associated with the specified identifier.

Remarks

An index partition is a data structure that has a specific number of parts. Each part is a collection of zero-based indexes represented by an instance of type IndexCollection, and has an identifier whose type is the generic parameter T.

Index partitions are useful when a collection of elements is inspected and its range must be partitioned by grouping those positions which share the same element. The resulting groups, referred to as parts, have no common indexes, and their union includes all the available positions in the collection of elements. Let us consider an array of doubles: an example of index partition is a data structure with two parts, in which the first part is used to store the array positions which correspond to positive entries, and a second part stores the non positive ones.

Index partition instances can be created by calling methods provided by the IndexPartition static class.
