This is a Map implementation driven by a data source that only
provides an enumeration of keys and a getValue(key) method. This
class must be subclassed to implement those methods.
Some of the methods may incur a performance penalty that
involves enumerating the entire data source. In these cases, the
Map will try to save the results of that enumeration, but only if
the underlying data source is immutable.
