Syntax

public static class CollectionsExtensions

Methods

AsReadOnly<TElement>(IList<TElement>)

Creates a read-only wrapper around an existing collection.

Declaration

public static ReadOnlyCollection<TElement> AsReadOnly<TElement>(this IList<TElement> elements)

Parameters

Type	Name	Description
IList<TElement>	elements	The collection to be wrapped.

Returns

Type	Description
ReadOnlyCollection<TElement>	The new, read-only wrapper around elements.

Type Parameters

Name	Description
TElement	The type of element in the collection.

DisposeElements<TElement>(IEnumerable<TElement>)

Disposes of all non-null elements in a collection.

Declaration

public static void DisposeElements<TElement>(this IEnumerable<TElement> elements)
    where TElement : IDisposable

Parameters

Type	Name	Description
IEnumerable<TElement>	elements	The collection of elements to be disposed.

Type Parameters

Name	Description
TElement	The type of element in the collection.

DisposeElements<TElement>(IList<TElement>)

Disposes of all non-null elements in a collection.

Declaration

public static void DisposeElements<TElement>(this IList<TElement> elements)
    where TElement : IDisposable

Parameters

Type	Name	Description
IList<TElement>	elements	The collection of elements to be disposed.

Type Parameters

Name	Description
TElement	The type of element in the collection.

ExportDictionaryValuesAsArray<T>(Dictionary<UInt32, T>)

Exports the values of a uint indexed Dictionary as an Array

Declaration

public static T[] ExportDictionaryValuesAsArray<T>(this Dictionary<uint, T> input)

Parameters

Type	Name	Description
Dictionary<UInt32, T>	input	Dictionary to be exported

Returns

Type	Description
T[]	array in the type of data stored in the Dictionary

Type Parameters

Name	Description
T	Type of data stored in the values of the Dictionary

GetInteractionByType(MixedRealityInteractionMapping[], DeviceInputType)

Overload extension to enable getting of an InteractionDefinition of a specific type

Declaration

public static MixedRealityInteractionMapping GetInteractionByType(this MixedRealityInteractionMapping[] input, DeviceInputType key)

Parameters

Type	Name	Description
MixedRealityInteractionMapping[]	input	The InteractionDefinition array reference
DeviceInputType	key	The specific DeviceInputType value to query

Returns

Type	Description
MixedRealityInteractionMapping

SortedInsert<TElement>(List<TElement>, TElement, IComparer<TElement>)

Inserts an item in its sorted position into an already sorted collection. This is useful if you need to consume the collection in between insertions and need it to stay correctly sorted the whole time. If you just need to insert a bunch of items and then consume the sorted collection at the end, it's faster to add all the elements and then use Sort() at the end.

Declaration

public static int SortedInsert<TElement>(this List<TElement> elements, TElement toInsert, IComparer<TElement> comparer = null)

Parameters

Type	Name	Description
List<TElement>	elements	The collection of sorted elements to be inserted into.
TElement	toInsert	The element to insert.
IComparer<TElement>	comparer	The comparer to use when sorting or null to use Default.

Returns

Type	Description
Int32

Type Parameters

Name	Description
TElement	The type of element in the collection.

SupportsInputType(MixedRealityInteractionMapping[], DeviceInputType)

Overload extension to enable getting of an InteractionDefinition of a specific type

Declaration

public static bool SupportsInputType(this MixedRealityInteractionMapping[] input, DeviceInputType key)

Parameters

Type	Name	Description
MixedRealityInteractionMapping[]	input	The InteractionDefinition array reference
DeviceInputType	key	The specific DeviceInputType value to query

Returns

Type	Description
Boolean

ToReadOnlyCollection<TElement>(IEnumerable<TElement>)

Creates a read-only copy of an existing collection.

Declaration

public static ReadOnlyCollection<TElement> ToReadOnlyCollection<TElement>(this IEnumerable<TElement> elements)

Parameters

Type	Name	Description
IEnumerable<TElement>	elements	The collection to be copied.

Returns

Type	Description
ReadOnlyCollection<TElement>	The new, read-only copy of elements.

Type Parameters

Name	Description
TElement	The type of element in the collection.
