Simon Willnauer commented on LUCENE-2662:
-----------------------------------------
bq. In the class jdocs, I think state that this is basically a
Map<BytesRef,int>?
yeah that simplifies it - will do.
bq. Maybe we also move ByteBlockPool --> oal.util?
yeah I did that already - that makes totally sense
bq. Maybe move out the ByteBlockAllocator to its own class (in util)?
RecyclingByteBlockAllocator?
+1 yeah I like that - I also think we should allow to pass the blockpool to the
byteshash instead of the allocator. From what I can tell now I think this is
necessary for the refactoring anyway since we share pools with secondary
TermsHash instances in the termvector case.
{quote}
Maybe rename ords -> keys? And hash -> values? (The key isn't
really an "ord" (I think?) because it increases by more than 1
each time... it's more like an address since it references an
address in the byte-pool space).
{quote}
yeah that depends how you see it - the array index really is the ord though.
but I like those names. I will change.
{quote}
We should advertise the limits in the jdocs - limited to <= 2GB
total byte storage, each key must be <= BLOCK SIZE-2 in length.
{quote}
I think I have done the latter already but I will add the other too.
{quote}
Can we have sortedEntries() not allocate a new iterator object?
Ie, just return the sorted bytesStart int[]? (This is what's done
today, and, for term vectors on small docs, this method is pretty
hot). And the javadocs for this should be stronger - it's not
that the behaviour is undefined after, it's that you must .clear()
after you're done consume the sorted entries.
{quote}
Ah I see - good point. I think what you refer to is public int[]
sort(Comparator<BytesRef> comp) - the iterator one is just more convenient one.
I will change though.
thanks mike!
