Hi Jody,
I like this road, works fine for FeatureSource.
What about FeatureCollection though? It's already using "int
size()", from the interface:
/** * Please note this operation may be expensive when working with
remote content. * * @see java.util.Collection#size() */ int size();
Cheers

Here is another softer approach:
/**
* @return Returns the number of features in this collection, if
this collection contains more than Integer.MAX_VALUE elements,
returns Integer.MAX_VALUE.
* @deprecated Please use count()
*/
public int getCount();
public long size();
This gives us a clear api migration and does not immediately
break projects when they upgrade. The size() name matches how
Collections.size() handles a size greater than the range of
Integer.MAX_VALUE.

Hi, any other opinion on this?
Personally I would not like breaking all existing store
implementations and clients, for a "clean break" it seems
quite bloody :-D
But Jody suggests to go that way.
Some tie breaker, or even multiple votes leading to another
tie, would be appreciated, ha!
Cheers

We are just about to start a new release cycle, API
changes are a short-term pain, but the most
maintainable approach long term.
As for the change, how about returning a returning
long? Existing client code that used integrer would
be easy to update.
long count = featureSource.getCount(query);
Or:
int count = (int) featureSource.getCount(query);
We can gauge how easy it is by doing the switch in GT/GS...
Maybe it could be done as a refactor... but I cannot
imagine exactly how yet. Closest thing to something
working may be:
1) Rename existing getCount to getCountOld via refactor
2) Add a new method called getCount, returning long,
make it abstract, have a default implementation of
getCountOld delegating to getCount
3) Fix all implementations, switching them from
getCountOld to getCount
4) Inline getCountOld, that should fix all calling points
Hopefully that should not be too much work, I hope there
are few implementations of FeatureSource/Collection but many
client code calls using them.
If you really want Java 8 has Math.toIntExact
method, that produces an exception if the long is
out of range:
int count = Math. toIntExact(
featureSource.getCount(query) );
That would also work yes
Cheers
