Overload List
TryAggregateWhere<TPredicate>(IEnumerable<T>, TPredicate, Boolean, TResult)
Aggregates the elements of a sequence and returns the result.
public override bool TryAggregateWhere<TPredicate>(
IEnumerable<T> values,
TPredicate predicate,
bool skipMissingValues,
out TResult result
)
where TPredicate : struct, new(), IFastFunc<T, bool>
Parameters
- values IEnumerable<T>
- A sequence of values.
- predicate TPredicate
- A predicate that filters the values that are to be included in the aggregation.
- skipMissingValues Boolean
- Specifies whether missing values should be excluded from the aggregation.
- result TResult
- On return, the result of the aggregation.
Type Parameters
- TPredicate
- The type of predicate.
Return Value
Booleantrue if the aggregation produced a result; otherwise false.
TryAggregateWhere<TPredicate>(ReadOnlySpan<T>, TPredicate, Boolean, TResult)
Aggregates the elements of a vector and returns the result.
public override bool TryAggregateWhere<TPredicate>(
ReadOnlySpan<T> values,
TPredicate predicate,
bool skipMissingValues,
out TResult result
)
where TPredicate : struct, new(), IFastFunc<T, bool>
Parameters
- values ReadOnlySpan<T>
- A read-only span of values.
- predicate TPredicate
- A predicate that filters the values that are to be included in the aggregation.
- skipMissingValues Boolean
- Specifies whether missing values should be excluded from the aggregation.
- result TResult
- On return, the result of the aggregation.
Type Parameters
- TPredicate
- The type of predicate.
Return Value
Booleantrue if the aggregation produced a result; otherwise false.
TryAggregateWhere<TPredicate>(Int32, ReadOnlySpan<T>, Int32, TPredicate, Boolean, TResult)
Aggregates the elements of a vector and returns the result.
public override bool TryAggregateWhere<TPredicate>(
int length,
ReadOnlySpan<T> values,
int stride,
TPredicate predicate,
bool skipMissingValues,
out 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.
- predicate TPredicate
- A predicate that filters the values that are to be included in the aggregation.
- skipMissingValues Boolean
- Specifies whether missing values should be excluded from the aggregation.
- result TResult
- On return, the result of the aggregation.
Type Parameters
- TPredicate
- The type of predicate.
Return Value
Booleantrue if the aggregation produced a result; otherwise false.
TryAggregateWhere<TPredicate>(Vector<T>, Int32, Int32, TPredicate, Nullable<Boolean>, TResult)
Aggregates the specified range of elements of a vector and returns the result.
public override bool TryAggregateWhere<TPredicate>(
Vector<T> values,
int startIndex,
int endIndex,
TPredicate predicate,
bool? skipMissingValues,
out TResult result
)
where TPredicate : struct, new(), IFastFunc<T, bool>
Parameters
- values Vector<T>
- A vector of values.
- startIndex Int32
- The zero-based index of the first element in values that should be aggregated.
- endIndex Int32
- The zero-based index of the last element in values that should be aggregated.
- predicate TPredicate
- A predicate that filters the values that are to be included in the aggregation.
- skipMissingValues Nullable<Boolean>
- Specifies whether missing values should be excluded from the aggregation. If null, then the value is inferred from values.
- result TResult
- On return, the result of the aggregation.
Type Parameters
- TPredicate
- The type of predicate.
Return Value
Booleantrue if the aggregation produced a result; otherwise false.
TryAggregateWhere<TPredicate>(Int32, ReadOnlySpan<T>, Int32, ReadOnlySpan<Int32>, TPredicate, Boolean, TResult)
