Method Detail
-
getField
public String getField()
Description copied from interface:TermFreqVector
TheFieldable
name.- Specified by:
getField
in interfaceTermFreqVector
- Returns:
- The name of the field this vector is associated with.
-
size
public int size()
- Specified by:
size
in interfaceTermFreqVector
- Returns:
- The number of terms in the term vector.
-
getTerms
public String[] getTerms()
- Specified by:
getTerms
in interfaceTermFreqVector
- Returns:
- An Array of term texts in ascending order.
-
getTermFrequencies
public int[] getTermFrequencies()
Description copied from interface:TermFreqVector
Array of term frequencies. Locations of the array correspond one to one to the terms in the array obtained fromgetTerms
method. Each location in the array contains the number of times this term occurs in the document or the document field.- Specified by:
getTermFrequencies
in interfaceTermFreqVector
-
indexOf
public int indexOf(String term)
Description copied from interface:TermFreqVector
Return an index in the term numbers array returned fromgetTerms
at which the term with the specifiedterm
appears. If this term does not appear in the array, return -1.- Specified by:
indexOf
in interfaceTermFreqVector
-
indexesOf
public int[] indexesOf(String[] terms, int start, int len)
Description copied from interface:TermFreqVector
Just likeindexOf(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.- Specified by:
indexesOf
in interfaceTermFreqVector
- Parameters:
terms
- array containing terms to look forstart
- index in the array where the list of terms startslen
- the number of terms in the list
