Method Details

iterator

public TermsEnum iterator()
                   throws IOException

Description copied from class: Terms

Returns an iterator that will step through all terms. This method will not return null.

Specified by:

iterator in class Terms

Throws:

IOException

size

public long size()
          throws IOException

Description copied from class: Terms

Returns the number of terms for this field, or -1 if this measure isn't stored by the codec. Note that, just like other term measures, this measure does not take deleted documents into account.

Specified by:

size in class Terms

Throws:

IOException

getSumTotalTermFreq

public long getSumTotalTermFreq()
                         throws IOException

Description copied from class: Terms

Returns the sum of TermsEnum.totalTermFreq() for all terms in this field. Note that, just like other term measures, this measure does not take deleted documents into account.

Specified by:

getSumTotalTermFreq in class Terms

Throws:

IOException

getSumDocFreq

public long getSumDocFreq()
                   throws IOException

Description copied from class: Terms

Returns the sum of TermsEnum.docFreq() for all terms in this field. Note that, just like other term measures, this measure does not take deleted documents into account.

Specified by:

getSumDocFreq in class Terms

Throws:

IOException

getDocCount

public int getDocCount()
                throws IOException

Description copied from class: Terms

Returns the number of documents that have at least one term for this field. Note that, just like other term measures, this measure does not take deleted documents into account.

Specified by:

getDocCount in class Terms

Throws:

IOException

hasFreqs

public boolean hasFreqs()

Description copied from class: Terms

Returns true if documents in this field store per-document term frequency (PostingsEnum.freq()).

Specified by:

hasFreqs in class Terms

hasOffsets

public boolean hasOffsets()

Description copied from class: Terms

Returns true if documents in this field store offsets.

Specified by:

hasOffsets in class Terms

hasPositions

public boolean hasPositions()

Description copied from class: Terms

Returns true if documents in this field store positions.

Specified by:

hasPositions in class Terms

hasPayloads
