GroupingPartitionT Method (IListT, Int32, Boolean, Boolean)

Extreme Optimization Numerical Libraries for .NET Professional
Constructs a grouping that represents a collection of non-overlapping chunks of fixed length.

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

C#
VB
C++
F#
Copy
public static Grouping<T> Partition<T>(
	IList<T> values,
	int size,
	bool alignToEnd = false,
	bool skipIncomplete = false
)
Public Shared Function Partition(Of T) ( 
	values As IList(Of T),
	size As Integer,
	Optional alignToEnd As Boolean = false,
	Optional skipIncomplete As Boolean = false
) As Grouping(Of T)
public:
generic<typename T>
static Grouping<T>^ Partition(
	IList<T>^ values, 
	int size, 
	bool alignToEnd = false, 
	bool skipIncomplete = false
)
static member Partition : 
        values : IList<'T> * 
        size : int * 
        ?alignToEnd : bool * 
        ?skipIncomplete : bool 
(* Defaults:
        let _alignToEnd = defaultArg alignToEnd false
        let _skipIncomplete = defaultArg skipIncomplete false
*)
-> Grouping<'T> 

Parameters

values
Type: System.Collections.GenericIListT
The collection the grouping is over.
size
Type: SystemInt32
The size of the chunks. Must be greater than zero.
alignToEnd (Optional)
Type: SystemBoolean
Indicates whether groups should be aligned starting from the end of the index.
skipIncomplete (Optional)
Type: SystemBoolean
Indicates whether the first or last group should be skipped if it does not have full size.

Type Parameters

T

Return Value

Type: GroupingT
A grouping object that represents the chunking.
Exceptions

ExceptionCondition
ArgumentNullException

values is

ArgumentOutOfRangeException

size is less than or equal to zero.

Remarks

If alignToEnd is (the default) then first element of values in each group is used as the key for the group. If alignToEnd is then the last element of values in each group is used as the key for the group.
