Interface TermFreqVector
- TermPositionVector
- QueryTermVector
public interface TermFreqVector
Provides access to stored term vector of
a document field.
String | getField()
|
int[] | getTermFrequencies() - Array of term frequencies.
|
String[] | getTerms()
|
int | indexOf(String term) - Return an index in the term numbers array returned from
getTerms at which the term with the specified
term appears.
|
int[] | indexesOf(String[] terms, int start, int len) - Just like
indexOf(int) but searches for a number of terms
at the same time.
|
int | size()
|
getField
public String getField()
- The field this vector is associated with.
getTermFrequencies
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.
getTerms
public String[] getTerms()
- An Array of term texts in ascending order.
indexOf
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.
indexesOf
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.
terms
- array containing terms to look forstart
- index in the array where the list of terms startslen
- the number of terms in the list
size
public int size()
- The number of terms in the term vector.
