Nested as[Type]
Nested as[Type]
A helper to recursively fetch and then finally cast items from a DBObject.
the type to cast the final key to
(String*)
(A)
NoSuchElementException or ClassCastException
as
as
Works like apply(), unsafe, bare return of a value. Returns default if nothing matching is found, else tries to cast a value to the specified type.
Unless you overrode it, default throws a NoSuchElementException
Any type as long as its not Nothing
(String)
(A)
NoSuchElementException or ClassCastException
A utility method that allows you to cast a value to an Option[A]
A utility method that allows you to cast a value to an Option[A]
Some(value.asInstanceOf[T]) would only cause a runtime ClassCastException when calling get
This utility ensures that the types match correctly (even boxed scala types eg Int) so we can check against the type and return Some(value) if the types match.
the type to cast to check against
the value to type check against
Option[A] - Some(value) if the type of instances match else None

Designed to simplify the occasional insanity of working with nested objects. Your type parameter must be that of the item at the bottom of the tree you specify...
If the cast fails it will return None

Strings the keys to lookup
Option[A] - None if value is None, the cast invalid or the key is missing otherwise Some(value)
Utility method to allow typing without conflicting with Map's required get() method and causing ambiguity.

(Changed in version 2.8.0) keys returns Iterable[A] rather than Iterator[A].
(Changed in version 2.9.0) The behavior of scanRight has changed. The previous behavior can be reproduced with scanRight.reverse.
(Changed in version 2.9.0) transpose throws an IllegalArgumentException if collections are not uniformly sized.
(Changed in version 2.8.0) values returns Iterable[B] rather than Iterator[B].
MapLike scala interface for Mongo DBObjects - proxies an existing DBObject. Cannot act as a DBObject or implement it's interface due to conflicts between the java methods and scala methods. Implicits and explicit methods allow you to convert to java though.
