Public Constructors
public PositionBasedTermVectorMapper ()
public PositionBasedTermVectorMapper (boolean ignoringOffsets)
Public Methods
public Map<String, Map<Integer, PositionBasedTermVectorMapper.TVPositionInfo>> getFieldToTerms ()
Get the mapping between fields and terms, sorted by the comparator
Returns
- A map between field names and a Map. The sub-Map key is the position as the integer, the value is
PositionBasedTermVectorMapper.TVPositionInfo.
public boolean isIgnoringPositions ()
Never ignores positions. This mapper doesn't make much sense unless there are positions
Returns
- false
public void map (String term, int frequency, TermVectorOffsetInfo[] offsets, int[] positions)
Callback for the TermVectorReader.
Parameters
| term | The term to add to the vector |
|---|---|
| frequency | The frequency of the term in the document |
| offsets | null if the offset is not specified, otherwise the offset into the field of the term |
| positions | null if the position is not specified, otherwise the position in the field of the term |
public void setExpectations (String field, int numTerms, boolean storeOffsets, boolean storePositions)
Callback mechanism used by the TermVectorReader
Parameters
| field | The field being read |
|---|---|
| numTerms | The number of terms in the vector |
| storeOffsets | Whether offsets are available |
| storePositions | Whether positions are available |
