CastingEnumerable
CastingEnumerable(
data: Sequence[
QuantConnect_Util_CastingEnumerable_TBase
],
)
Bases: Generic[QuantConnect_Util_CastingEnumerable_TBase, QuantConnect_Util_CastingEnumerable_TDerived], Object, Sequence[QuantConnect_Util_CastingEnumerable_TDerived], Iterable[QuantConnect_Util_CastingEnumerable_TDerived]
Defines a list that casts the elements of a source list to a derived type. This is useful to avoid materializing another list after using, for example, the Enumerable.Cast{TResult}(IEnumerable) LINQ method.
Initializes a new instance of the CastingEnumerable{TBase, TDerived} class
count: int
Gets the count of items in the enumerable.
__getitem__(
index: int,
) -> QuantConnect_Util_CastingEnumerable_TDerived
Gets the element at the specified index.
Parameters:
| Name | Type | Description | Default |
|---|---|---|---|
index
|
int
|
The zero-based index of the element to get. |
required |
Returns:
| Type | Description |
|---|---|
QuantConnect_Util_CastingEnumerable_TDerived
|
The element at the specified index. |
__iter__() -> (
Iterator[QuantConnect_Util_CastingEnumerable_TDerived]
)
__len__() -> int
get_enumerator() -> (
IEnumerator[
QuantConnect_Util_CastingEnumerable_TDerived
]
)
Returns an enumerator that iterates through the collection.
Returns:
| Type | Description |
|---|---|
IEnumerator[QuantConnect_Util_CastingEnumerable_TDerived]
|
An enumerator that can be used to iterate through the collection. |
