implementations.
NOTE: If the order of terms and documents is not changed, and if
these terms are going to be intersected with automata, you could consider
overriding Terms.intersect(org.apache.lucene.util.automaton.CompiledAutomaton, org.apache.lucene.util.BytesRef)
for better performance.

int |
getDocCount()
Returns the number of documents that have at least one
term for this field, or -1 if this measure isn't
stored by the codec.
|
Object |
getStats()
Expert: returns additional information about this Terms instance
for debugging purposes.
|
long |
getSumDocFreq()
Returns the sum of
TermsEnum.docFreq() for
all terms in this field, or -1 if this measure isn't
stored by the codec. |
long |
getSumTotalTermFreq()
Returns the sum of
TermsEnum.totalTermFreq() for
all terms in this field, or -1 if this measure isn't
stored by the codec (or if this fields omits term freq
and positions). |
boolean |
hasFreqs()
Returns true if documents in this field store
per-document term frequency (
DocsEnum.freq() ). |
boolean |
hasOffsets()
Returns true if documents in this field store offsets.
|
boolean |
hasPayloads()
Returns true if documents in this field store payloads.
|
boolean |
hasPositions()
Returns true if documents in this field store positions.
|
TermsEnum |
iterator(TermsEnum reuse)
Returns an iterator that will step through all
terms.
|
long |
size()
Returns the number of terms for this field, or -1 if this
measure isn't stored by the codec.
