Hi,
I'm using a recursive tree of hashmaps, specifically Hashmap map where Object is a reference to another Hashmap and so on. This will be passed around a recursive algorithm:
foo(String filename, Hashmap<String, Object> map)
{
//some stuff here
for (Entry<String, Object> entry : map.entrySet())
{
//type warning that must be suppressed
foo(entry.getKey(), (HashMap<String, Object>)entry.getValue());
}
}
I know for sure Object
is of type Hashmap<String, Object>
but am irritated that I have to suppress the warning using @SuppressWarnings("unchecked")
.
I'll be satisfied with a solution that does either a assert(/*entry.getValue() is of type HashMap<String, Object>*/)
or throws an exception when it isn't. I went down the Generics route for compile type safety and if I suppress the warning then it defeats the purpose.
Thank you for your comments, ksb
