Sorry, im not familiar with generics, i can create a generic class like the following:
public class InfoField <T, U> {
}
The class above can accept values like:
<String, User>
<String, String>
<Set<UserGroup>, User>
But can i have class that accept map object as value? something like
<Map<String, String>, String>
public class InfoFieldMap <Map<T,U>, K> {
}
Works as you original had it:
class InfoField <T, U> {
public static void main( String[] args )
{
//Example InfoField declaration
InfoField<Map<String,String>, String> test;
}
}
I am not sure that you can have a Map as the key of another Map as you declared in your InfoFieldMap class. see this simple example: map-in-java-with-example
Your declation of InfoFieldMap class should be:
public class InfoFieldMap <K, Map<K,V>> {
}
Where K is key field of the Map and V is the value of the Map. V can be a Map or another collection.
I believe you've to do something like this
public class InfoFieldMap < Z extends Map<K,V>, K, V>
