Christian Ziech updated LUCENE-5670:
------------------------------------
Attachment: LUCENE-5670.patch
Attached an (untested) patch where a "skipOutput" method is added to the
outputs which doesn't create excess objects. Default implementation is the
current behavior by invoking the read() method.
Also a skipBytes(int) method was added to the DataInput which defaults to
reading the data as before. Several implementations of the DataInput already
had a skipBytes() method and now effectively implement it.
> org.apache.lucene.util.fst.FST should skip over outputs it is not interested
> in

>
> Currently the FST uses the read(DataInput) method from the Outputs class to
> skip over outputs it actually is not interested in. For most use cases this
> just creates some additional objects that are immediately destroyed again.
> When traversing an FST with non-trivial data however this can easily add up
> to several excess objects that nobody actually ever read.
