Jag har försökt att itera igenom en karta jag har gjort: getMinTreeHeight (TreeList, TreeMap) -> listor: foreach (fun (X) -> TreeMap # {X => getTreeHeight (X)} end, 

Maps are ordered by size, two maps with the same size are compared by keys in ascending term order and then by values in key order. In maps key order integers types are considered less than floats types. Atoms are compared using their string value, codepoint by codepoint.

The BIFs erlang:fun_info/1,2 can be used to retrieve information about a fun, and the BIF erlang:fun_to_list/1 returns a textual representation of a fun. The check_process_code/2 BIF returns true if the process contains funs that depend on the old version of a module. GitHub is where people build software.

Distributed Erlang and Map-Reduce The goal of this lab is to make the naïve map-reduce implementation presented in the lecture, a little less naïve.

To list every value stored in, you can list every key, and return key/value pair. This first loop give you an idea: loop(Map) when is_map(Map) -> Keys = maps:keys(Map), loop(Map, Keys).

Mapping of protocol buffer datatypes to erlang Repeated fields are represented as lists. Optional fields are represented as either the value or undefined if not set.

Map in Erlang is equivalent of hashes in Perl or dictionaries in Python, its a key/value store. To list every value stored in, you can list every key, and return key/value pair. This first loop give you an idea: loop(Map) when is_map(Map) -> Keys = maps:keys(Map), loop(Map, Keys).
