IIndex Interface

Extreme Optimization Numerical Libraries for .NET Professional

This API is preliminary and subject to change.

Defines the properties and methods common to all indexes.

Namespace:  Extreme.DataAnalysis
Assembly:  Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.1

Syntax

---

C#

VB

C++

F#

Copy

public interface IIndex : ICollection, IEnumerable

Public Interface IIndex
	Inherits ICollection, IEnumerable

public interface class IIndex : ICollection, 
	IEnumerable

type IIndex =  
    interface
        interface ICollection
        interface IEnumerable
    end

The IIndex type exposes the following members.

Properties

---

	Name	Description
	Count	Gets the number of elements contained in the ICollection. (Inherited from ICollection.)
	Depth	Gets the number of levels in the index.
	IsSynchronized	Gets a value indicating whether access to the ICollection is synchronized (thread safe). (Inherited from ICollection.)
	ItemIEnumerableInt32	Gets a subset of the index.
	ItemIListBoolean	Gets a subset of the index defined by a boolean mask.
	ItemInt32	Gets the element at the specified position.
	KeyType	Gets the type of the keys.
	Length	Gets the number of items in the index.
	Name	Gets or sets the name of the index.
	SyncRoot	Gets an object that can be used to synchronize access to the ICollection. (Inherited from ICollection.)

Methods

---

	Name	Description
	CopyTo	Copies the elements of the ICollection to an Array, starting at a particular Array index. (Inherited from ICollection.)
	GetEnumerator	Returns an enumerator that iterates through a collection. (Inherited from IEnumerable.)
	GetSlice	Returns a new index containing the specified slice of the current index.
	JoinWith	Returns the index that is the result of applying the specified join to this index and another index.
	JoinWithNearest	Returns the index that is the result of applying the specified join to this index and another index where lookups are to the nearest key in the specified direction.
	Lookup	Looks up the position of the specified key.
	MakeVector	Returns a categorical vector that uses the index as categories.
	Permute	Applies a permutation to the index and returns the result.
	Sort	Returns a permutation that can be used to sort the data in the vector in the specified order.
