public interface Mutate<T>
extends org.apache.commons.collections.Transformer

Mutates an object of type T, to merge its values into the input (parent) object and produce a resultant Object of type T.
The resultant object is implementation dependent if its an existing modified object or a clone modified.

Further the override will state the nature of the merge @ the field level using #getMergeType().
