I\'m trying to extend a library that uses generics in entities and entities manager, so I have the following:
What is wrong with private Map<List<K>, V> multiMap= new HashMap<ArrayList<K>,V>();
If I have a class using generic type such as public class Record<T> { private T value; public Record(T value) {
I have an enum public enum Vehicle { CAR(\"CAR\", \"Car\"), PUSHBIKE(\"PUSHBIKE\", \"PuschBike\"); publicboolean isCar()
Lets assume I want to have a class that acts a descriptor for records, where each record has a set of attributes.
Rather than create a whole new class implementing ILookup<T> is it possible to add an extension method to dictionary which caters for it? I\'m thinking something along the following:
I can\'t find any example where wildcards can\'t be replaced by a generic. For example: public void dummy(List<? extends MyObject> list);
I was wondering, if there is an extension method that allow me to iterate a List and l开发者_Go百科et me do the same thing with every item in the list. For example:
How to make the following extension works? I\'m binding the ComboBoxe to an enum and in this case it doesn\'t compile because it returns null.
