  AbstractIterableGetMapDecorator<K,V> | `IterableGet` that uses a `Map`<K, V> for the `Get`<K, V> implementation.
  TransformedSplitMap<J,K,U,V> | Decorates another `Map` to transform objects that are added.

## Package org.apache.commons.collections4.splitmap Description

The "split map" concept is that of an object that implements the `Put` and `Get` interfaces, with differing generic types. This is like a pre-generics `Map` whose input key/value constraints are different than its output key/value constraints. While it would be possible to declare a "split map" with matching input/output key/value constraints, this would be a `Map` and would therefore make little sense (any Commons Collections `Map` implementation will also implement `Put` and `Get` with matching generic parameters).

The following decorators are provided:

- Transformed - transforms each element added
