MoreEnumerableRunLengthEncodeT Method (IEnumerableT, IEqualityComparerT) |
Run-length encodes a sequence by converting consecutive instances of the same element into
a KeyValuePair{T,int} representing the item and its occurrence count. This overload
uses a custom equality comparer to identify equivalent items.
Namespace:
MoreLinq
Assembly:
MoreLinq (in MoreLinq.dll) Version: 3.0.0
Syntax public static IEnumerable<KeyValuePair<T, int>> RunLengthEncode<T>(
this IEnumerable<T> sequence,
IEqualityComparer<T> comparer
)
<ExtensionAttribute>
Public Shared Function RunLengthEncode(Of T) (
sequence As IEnumerable(Of T),
comparer As IEqualityComparer(Of T)
) As IEnumerable(Of KeyValuePair(Of T, Integer))
public:
[ExtensionAttribute]
generic<typename T>
static IEnumerable<KeyValuePair<T, int>>^ RunLengthEncode(
IEnumerable<T>^ sequence,
IEqualityComparer<T>^ comparer
)
[<ExtensionAttribute>]
static member RunLengthEncode :
sequence : IEnumerable<'T> *
comparer : IEqualityComparer<'T> -> IEnumerable<KeyValuePair<'T, int>>
Parameters
- sequence
- Type: System.Collections.GenericIEnumerableT
The sequence to run length encode - comparer
- Type: System.Collections.GenericIEqualityComparerT
The comparer used to identify equivalent items
Type Parameters
- T
- The type of the elements in the sequence
Return Value
Type:
IEnumerableKeyValuePairT,
Int32A sequence of
KeyValuePair{T,int} where they key is the element and the value is the occurrence count
Usage Note
In Visual Basic and C#, you can call this method as an instance method on any object of type
IEnumerableT. When you use instance method syntax to call this method, omit the first parameter. For more information, see
Extension Methods (Visual Basic) or
Extension Methods (C# Programming Guide).
