Detailed Description

template<class K, class V>
class drain::Dictionary< K, V >

Two-way mapping between strings and objects of template class T.

TODO: hide first and second so that an entry cannot be assigned to either of them Simple list based container for small dictionaries. Uses brute-force linear search.

In a way, works like std::map as each entry is a std::pair. However, no less-than relation is needed as the entries are not in order but appended sequentially.

For handling input and output, dictionary has a separator char which is a comma ',' by default.

Identity mapping useful for type deduction of template arguments in functions.

 Consider setProperty(const T & prop) supporting both enum and string argument, for example.

const V & getValue(const V & value) const { return value; } Given a value, return the first key associated with it.
