AngelScript
dictionary object

Path: /sdk/add_on/scriptdictionary/

The dictionary object maps string values to values or objects of other types.

Register with RegisterScriptDictionary(asIScriptEngine*).

Compile the add-on with the pre-processor define AS_USE_STLNAMES=1 to register the methods with the same names as used by C++ STL where the methods have the same significance. Not all methods from STL is implemented in the add-on, but many of the most frequent once are so a port from script to C++ and vice versa might be easier if STL names are used.
