CharArraySet.clear()
--------------------
Key: LUCENE-2179
URL: https://issues.apache.org/jira/browse/LUCENE-2179
Project: Lucene - Java
Issue Type: Improvement
Components: Analysis
Reporter: Robert Muir
Priority: Minor
Fix For: 3.1
I needed CharArraySet.clear() for something I was working on in Solr in a
tokenstream.
instead I ended up using CharArrayMap<Boolean> because it supported .clear()
it would be better to use a set though, currently it will throw UOE for
.clear() because AbstractSet will call iterator.remove() which throws UOE.
In Solr, the very similar CharArrayMap.clear() looks like this:
{code}
@Override
public void clear() {
count = 0;
Arrays.fill(keys,null);
Arrays.fill(values,null);
}
{code}
I think we can do a similar thing as long as we throw UOE for the
UnmodifiableCharArraySet
will submit a patch later tonight (unless someone is bored and has nothing
better to do)
