TermFreqVector (Lucene 3.6.2 API)

All Known Subinterfaces:

TermPositionVector

All Known Implementing Classes:

QueryTermVector
```
public interface TermFreqVector
```
Provides access to stored term vector of a document field. The vector consists of the name of the field, an array of the terms that occur in the field of the 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.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`String`	`getField()`	The `Fieldable` name.
`int[]`	`getTermFrequencies()`	Array of term frequencies.
`String[]`	`getTerms()`
`int[]`	`indexesOf(String[] terms, int start, int len)`	Just like `indexOf(int)` but searches for a number of terms at the same time.
`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`	`size()`

- Method Detail
  - getField
```
String getField()
```
    The Fieldable name.
    
    Returns:
    
    The name of the field this vector is associated with.
  - size
```
int size()
```
    Returns:
    
    The number of terms in the term vector.
  - getTerms
```
String[] getTerms()
```
    Returns:
    
    An Array of term texts in ascending order.
  - getTermFrequencies
```
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.
  - indexOf
```
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
```
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.
    
    Parameters:
    
    terms - array containing terms to look for
    
    start - index in the array where the list of terms starts
    
    len - the number of terms in the list
