AsCollection< ItemType >()

static Collection< ItemType > Joutsen.Linq.EnumerableExtensions.AsCollection< ItemType > ( this SCG.IEnumerable< ItemType >  collection )

static

Creates a Collection out of an Icollection.

Parameters

collection

the collection

Returns

the ICollection as a collection

Remarks

This method does not copy the elements of the collection but uses a thin wrapper. Therefore it should not be performance critical.

AsList< ItemType >()

static List< ItemType > Joutsen.Linq.EnumerableExtensions.AsList< ItemType > ( this SCG.IEnumerable< ItemType >  enumerable )

static

Creates a list out of an enumerable.

Parameters

collection

the collection of items

Since

0.4.0

AsListable< ItemType >()

static Listable< ItemType > Joutsen.Linq.EnumerableExtensions.AsListable< ItemType > ( this SCG.IEnumerable< ItemType >  collection )

static

Converts an IEnumerable to a Listable.

Parameters

collection

the IEnumerable

Returns

a Listable based on collection

Remarks

This method copies the elements of the IEnumerable to a new data structure. It is as performant as the ToList method in the System.Linq namespace.

Since

0.4.0

AsMap< ItemType, KeyType, ValueType >()

static Map< KeyType, ValueType > Joutsen.Linq.EnumerableExtensions.AsMap< ItemType, KeyType, ValueType > ( this SCG.IEnumerable< ItemType >  enumerable, Func< ItemType, KeyType >  keyProjection, Func< ItemType, ValueType >  valueProjection  )

static

Creates a map out of an enumerable.

Parameters

collection	the collection of items
keyProjection	a function that determines the keys of the resulting map
valueProjection	a function that determines the values of the resulting map

Since

0.4.0

AsSet< ItemType >()

static Set< ItemType > Joutsen.Linq.EnumerableExtensions.AsSet< ItemType > ( this SCG.IEnumerable< ItemType >  set )

static

Converts an ISet to a Set.

Parameters

set

the ISet

Returns

a Set based on the ISet

Remarks

This method does not copy the elements of the ISet but uses a thin wrapper. Therefore it should not be performance critical.

StandardDeviation() [1/6]

static double Joutsen.Linq.EnumerableExtensions.StandardDeviation ( this SCG.IEnumerable< float >  collection )

static

Calculates the standard deviation of the items in the collection.

Parameters

Since

0.4.0

StandardDeviation() [3/6]

static double Joutsen.Linq.EnumerableExtensions.StandardDeviation ( this SCG.IEnumerable< int >  collection )

static

Since

0.4.0

StandardDeviation() [6/6]

static double Joutsen.Linq.EnumerableExtensions.StandardDeviation ( this SCG.IEnumerable< ulong >  collection )

static

Since

0.4.0

StandardDeviation< Type >()

static double Joutsen.Linq.EnumerableExtensions.StandardDeviation< Type > ( this SCG.IEnumerable< Type >  collection, Func< Type, double >  selector  )
