[Type] Map
Part of: mobl
Inherits from: mobl::Object
Represents a map, also known as hash map or dictionary. It maintains a key-value store.
Instantiation
A new Map can be created using the Map<K,V>() constructor, where K is the type of the keys and V the type of values.
Example:
var m = Map<String, Object>();
m.set("name", "Zef");
m.set("age", 27);
Instance methods
get(key : K) : V
Returns the value associated with key, returns null when no such key has been defined.
Example:
var m = Map<String, Object>();
m.set("name", "Zef");
m.set("age", 27);
m.get("name") // -> "Zef"
set(key : K, value : V) : void
Sets the value associated with key to value.
Example:
var m = Map<String, Object>();
m.set("name", "Zef");
keys() : [K]
Returns a list of defines keys.
Example:
var m = Map<String, Object>();
m.set("name", "Zef");
m.set("age", "Zef");
m.keys() // -> ["name", "age"]
