AggregateInto<TPredicate>(Int32, ReadOnlySpan<T>, Int32, ReadOnlySpan<Int32>, Int32, Int32, TPredicate, Boolean, SpanSlice<TResult>)
Groups the elements of a vector according to the specified level indexes.
public override void AggregateInto<TPredicate>(
int length,
ReadOnlySpan<T> values,
int stride,
ReadOnlySpan<int> levels,
int levelsStride,
int maxLevel,
TPredicate predicate,
bool skipMissingValues,
SpanSlice<TResult> result
)
where TPredicate : struct, new(), IFastFunc<T, bool>
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.
