toObjectId
open fun <R : Any> Value<R, *>.toObjectId(): Value<R, ERROR CLASS: Symbol not found for ObjectId>(source)
Converts this value to an ObjectId.
Conversion algorithm
BsonType.ObjectId is returned as itself.
BsonType.String is parsed as an ObjectId as a 24-character hexadecimal representation, for example "5ab9cbfa31c2ab715d42129e".
BsonType.Null always returns null.
Other types throw an exception.
Example
class Product(
val _id: ObjectId,
)
// Migrate ids which were accidentally written as strings:
products.updateManyWithPipeline {
_id set of(Product::_id).toObjectId()
