HashMap implementation - MetaTrader 4 library | MT4 EA download - MetaTrader 4 resources
This is a HashMap implementation. This allows something like an array but with string indexing. It maps strings to objects. The object must be a subclass of the provided HashValue class.
By default, the hash will "take" a value object. In this case it will free the memory when they are no longer in the hash. This can be disabled in the constructor.
The codebase version may not be the latest. The latest version can be found here .
Below is an example, mine also uses the JSON parser class to represent JSON objects.
