Method Details

next
Description copied from interface:BytesRefIterator
Increments the iteration to the nextBytesRef
in the iterator. Returns the resultingBytesRef
ornull
if the end of the iterator is reached. The returned BytesRef may be re-used across calls to next. After this method returns null, do not call it again: the results are undefined.- Returns:
- the next
BytesRef
in the iterator ornull
if the end of the iterator is reached. - Throws:
IOException
- If there is a low-level I/O error.
-
seekExact
Description copied from class:TermsEnum
Seeks to the specified term by ordinal (position) as previously returned byTermsEnum.ord()
. The target ord may be before or after the current ord, and must be within bounds.- Specified by:
seekExact
in classTermsEnum
- Throws:
IOException

- Throws:

seekCeil
Description copied from class:TermsEnum
Seeks to the specified term, if it exists, or to the next (ceiling) term. Returns SeekStatus to indicate whether exact term was found, a different term was found, or EOF was hit. The target term may be before or after the current term. If this returns SeekStatus.END, the enum is unpositioned.- Specified by:
seekCeil
in classTermsEnum
- Throws:
IOException
-
term
Description copied from class:TermsEnum
Returns current term. Do not call this when the enum is unpositioned.- Specified by:
term
in classTermsEnum
- Throws:
IOException
-
ord
Description copied from class:TermsEnum
Returns ordinal position for current term. This is an optional method (the codec may throwUnsupportedOperationException
). Do not call this when the enum is unpositioned.- Specified by:
ord
in classTermsEnum
- Throws:
IOException
-
totalTermFreq
Description copied from class:TermsEnum
Returns the total number of occurrences of this term across all documents (the sum of the freq() for each doc that has this term). Note that, like other term measures, this measure does not take deleted documents into account.- Specified by:
totalTermFreq
in classTermsEnum
- Throws:
IOException
-
postings
Description copied from class:TermsEnum
GetPostingsEnum
for the current term, with control over whether freqs, positions, offsets or payloads are required. Do not call this when the enum is unpositioned. This method will not return null.NOTE: the returned iterator may return deleted documents, so deleted documents have to be checked on top of the
PostingsEnum
.- Specified by:
postings
in classTermsEnum
- Parameters:
reuse
- pass a prior PostingsEnum for possible reuseflags
- specifies which optional per-document values you require; seePostingsEnum.FREQS
- Throws:
IOException

impacts
Description copied from class:TermsEnum
Return aImpactsEnum
.- Specified by:
impacts
in classTermsEnum
- Throws:
IOException
