public interface: TermFreqVector [javadoc |
source]
All Known Implementing Classes:
SegmentTermPositionVector, TermPositionVector, SegmentTermVector, QueryTermVector
Provides access to stored term vector of
a document field. The vector consists of the name of the field, an array of the terms tha occur in the field of the
org.apache.lucene.document.Document and a parallel array of frequencies. Thus, getTermFrequencies()[5] corresponds with the
frequency of getTerms()[5], assuming there are at least 5 terms in the Document.

 public String getField()
|
public int[] getTermFrequencies() Array of term frequencies. Locations of the array correspond one to one
to the terms in the array obtained from getTerms
method. Each location in the array contains the number of times this
term occurs in the document or the document field. |
public String[] getTerms() |
public int indexOf(String term) Return an index in the term numbers array returned from
getTerms at which the term with the specified
term appears. If this term does not appear in the array,
return -1. |
public int[] indexesOf(String[] terms,
int start,
int len) Just like indexOf(int) but searches for a number of terms
at the same time. Returns an array that has the same size as the number
of terms searched for, each slot containing the result of searching for
that term number. |
