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

  NameDescription
Public propertyCount
Gets the number of elements contained in the ICollection.
(Inherited from ICollection.)
Public propertyDepth
Gets the number of levels in the index.
Public propertyIsSynchronized
Gets a value indicating whether access to the ICollection is synchronized (thread safe).
(Inherited from ICollection.)
Public propertyItemIEnumerableInt32
Gets a subset of the index.
Public propertyItemIListBoolean
Gets a subset of the index defined by a boolean mask.
Public propertyItemInt32
Gets the element at the specified position.
Public propertyKeyType
Gets the type of the keys.
Public propertyLength
Gets the number of items in the index.
Public propertyName
Gets or sets the name of the index.
Public propertySyncRoot
Gets an object that can be used to synchronize access to the ICollection.
(Inherited from ICollection.)

Methods

  NameDescription
Public methodCopyTo
Copies the elements of the ICollection to an Array, starting at a particular Array index.
(Inherited from ICollection.)
Public methodGetEnumerator
Returns an enumerator that iterates through a collection.
(Inherited from IEnumerable.)
Public methodGetSlice
Returns a new index containing the specified slice of the current index.
Public methodJoinWith
Returns the index that is the result of applying the specified join to this index and another index.
Public methodJoinWithNearest
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.
Public methodLookup
Looks up the position of the specified key.
Public methodMakeVector
Returns a categorical vector that uses the index as categories.
Public methodPermute
Applies a permutation to the index and returns the result.
Public methodSort
Returns a permutation that can be used to sort the data in the vector in the specified order.
