Overload List

AggregateBy(Vector<T>, IGrouping, Vector<TResult>)	Groups the elements of a vector according to the specified grouping.
AggregateBy(Vector<T>, ReadOnlySpan<Int32>, Nullable<Boolean>, Vector<TResult>)	Aggregates the elements of a vector according to the specified level indexes.
AggregateBy<TPredicate>(Vector<T>, ReadOnlySpan<Int32>, TPredicate, Nullable<Boolean>, Vector<TResult>)	Groups the elements of a vector according to the specified level indexes.

AggregateBy(Vector<T>, ReadOnlySpan<Int32>, Nullable<Boolean>, Vector<TResult>)

Aggregates the elements of a vector according to the specified level indexes.

public override Vector<TResult> AggregateBy(
	Vector<T> values,
	ReadOnlySpan<int> levels,
	bool? skipMissingValues,
	Vector<TResult> result
)

Visual Basic

Public Overrides Function AggregateBy ( 
	values As Vector(Of T),
	levels As ReadOnlySpan(Of Integer),
	skipMissingValues As Boolean?,
	result As Vector(Of TResult)
) As Vector(Of TResult)

C++/CLI

public:
virtual Vector<TResult>^ AggregateBy(
	Vector<T>^ values, 
	ReadOnlySpan<int> levels, 
	Nullable<bool> skipMissingValues, 
	Vector<TResult>^ result
) override

abstract AggregateBy : 
        values : Vector<'T> * 
        levels : ReadOnlySpan<int> * 
        skipMissingValues : Nullable<bool> * 
        result : Vector<'TResult> -> Vector<'TResult> 
override AggregateBy : 
        values : Vector<'T> * 
        levels : ReadOnlySpan<int> * 
        skipMissingValues : Nullable<bool> * 
        result : Vector<'TResult> -> Vector<'TResult>

Parameters

values Vector<T>: The vector to aggregate.
levels ReadOnlySpan<Int32>: An array of level indexes.
skipMissingValues Nullable<Boolean>: Specifies whether missing values should be excluded from the aggregation. If null, then the value is inferred from values.
result Vector<TResult>: The vector that is to hold the result. May be null.

Return Value

Vector<TResult>
