Maintain 2 associative lookups for 2 separate keys and 1 value. The interface creates a bidirectional lookup where key1 can store multiple key2 associations to the same value. The supplied data structure module must have dict interface functions.

Data Types

dict_proxy()

dict_proxy(_Key, _Value) = any()

dict()/dict:dict() difference

key1()

key1() = any()

key2()

key2() = any()

key2value()

key2value(Key1, Key2, Value) = key2value_dict(Key1, Key2, Value) | #key2value{}

key2value_dict()

key2value_dict(Key1, Key2, Value) = {key2value, dict, dict_proxy(Key1, {[Key2], Value}), dict_proxy(Key2, {[Key1], Value})}

value()

value() = any()
