James Carman commented on LANG-425:
-----------------------------------
Perhaps we come up with a generified interface? Something like:
{code}
public interface Sequence<T>
{
public T nextValue();
}
{code}
This just sounds a lot like Iterator<T>, though except the idea of hasNext()
might not be applicable here. To adapt a Sequence to the Iterator interface we
could do:
{code}
public class SequenceIterator<T> implements Iterator<T>
{
private final Sequence<T> sequence;
public T next()
{
return sequence.nextValue();
}
public boolean hasNext()
{
return true;
}
}
{code}
Thus, if code needs a sequence of Integers (or ints with autoboxing), they
would declare their API with Sequence<Integer>. If they need a sequence of
strings, they would do Sequence<String>.

> Key: LANG-425
> URL: https://issues.apache.org/jira/browse/LANG-425
> Project: Commons Lang
> Issue Type: Wish
> Affects Versions: 2.4
> Reporter: Robert Scholte
> Priority: Trivial
>
> Don't you think it's kind of strange to have RandomUtils and
> RandomStringUtils, but not just the ordinairy SequenceUtils?
> I've seen commons-id in the sandbox, but maybe some basics should become part
> of commons lang.
> Most classes of within this package are stateless/static, or they have a
> state within a method (such as StrBuilder). SequenceUtils can only be static,
> if it has the startValue.
> For example
> {code}
> SequenceUtils.nextInt(10)
> SequenceUtils.nextString("MORE")
> SequenceUtils.nextBoolean(true) //ok, this one is stupid but quite clear
> SequenceUtils.nextString("C0DE", "0123456789ABCDEF") //next hexadecimal
> {code}
> any more ideas?
