1) I think the intent was to support avro arrays with more than 2 billion
elements eventually. Additionally the underlying serialized array size in the
avro spec is a long, not an int.
2) We could add something to get items by index but it could only work on
small arrays that are not streamed. I don't think the Generic interface
supports streaming large arrays yet anyway.
Generally, most users will loop over an array using the Java 5 syntax that
hides the iterator creation and get() call:
GenericArray<SomeType> array;
for (SomeType item : array) {
doSomething(item);
}
Rather than something like
for (i = 0; i < size; i++) {
SomeType item = array.get(i);
doSomething(item);
}

Subject: Two questions about GenericArray in the Java implementation
1) Why does size() return a long instead of an int? java.util.List, for
example, returns an int. Not returning an int leads to a lot of lint.
2) Why is there no get(index i) method? I can get an iterator and
continually call next(), but sometimes you want to look up a single element
by index.
My apologies if these are dumb questions; I know very little about Java.
Thanks,
Jeff
