Custom Containers
Custom containers is a simple way to provide own implementation of standard container types, thus allowing for easy extensibility of the collections language.
Example: weakHashMap
Provided the following declaration is reachable from the model currently being edited...
... one can use the weak version of hashmap thusly:
map<Object, int> myMap= new weakHashMap<Object, int>;
