-------------------------------------
Summary: Make Tuple Iterable
Key: PIG-2724
URL: https://issues.apache.org/jira/browse/PIG-2724
Project: Pig
Issue Type: Improvement
Reporter: Jonathan Coveney
Assignee: Jonathan Coveney
Fix For: 0.11
Seriously, is there a more annoying pattern than the following?
{code}
for (int i = 0; i < t.size(); i++) {
try {
doStuff(t.get(i));
} catch (ExecException e) {
throw new RuntimeException("BUT I THOUGHT PIG WAS SINGLETHREADED", e);
}
}
{code}
I mean yeah, you can do the following:
{code}
for (Object o : t.getAll()) {
doStuff(o);
}
{code}
But I don't even think that should be necessary. I think the following should
work:
{code}
for (Object o : t) {
doStuff(o);
}
{code}
It's a shame we can't give a default implementation (I either shake my fist
that this won't be possible until Java 8 OR that Tuple is an interface and not
an abstract class). Either way, I even added test! WOAH.
Thoughts?
