bits
Description copied from class:DocIdSet
Optionally provides aBits
interface for random access to matching documents.- Overrides:
bits
in classDocIdSet
- Returns:
null
, if thisDocIdSet
does not support random access. In contrast toDocIdSet.iterator()
, a return value ofnull
does not imply that no documents match the filter! The default implementation does not provide random access, so you only need to implement this method if your DocIdSet can guarantee random access to every docid in O(1) time without external disk access (asBits
interface cannot throwIOException
). This is generally true for bit sets likeFixedBitSet
, which return itself if they are used asDocIdSet
.- Throws:
IOException
-
ramBytesUsed
public long ramBytesUsed()Description copied from interface:Accountable
Return the memory usage of this object in bytes. Negative values are illegal. -
iterator
Description copied from class:DocIdSet
Provides aDocIdSetIterator
to access the set. This implementation can returnnull
if there are no docs that match.- Specified by:
iterator
in classDocIdSet
- Throws:
IOException
