Parameters

length Int32: The number of elements in the input.
values ReadOnlySpan<T>: A read-only span of values.
stride Int32: The distance between successive elements in values.
levels ReadOnlySpan<Int32>: An array of level indexes.
levelsStride Int32: The distance between successive elements in levels.
maxLevel Int32: The number of levels in levels.
predicate TPredicate: A predicate that filters the values that are to be included in the aggregation.
skipMissingValues Boolean: Optional. Specifies whether missing values should be excluded from the aggregation. The default is false.
result SpanSlice<TResult>: The span that is to hold the result. May be null.

Type Parameters

TPredicate: The type of predicate.

Remarks

The elements of levels must be less than maxLevel. Negative values are considered missing and are not included in the aggregation.
