java.lang.Object
   org.apache.lucene.index.TermVectorMapper
      org.apache.lucene.index.PositionBasedTermVectorMapper

PositionBasedTermVectorMapper
public class PositionBasedTermVectorMapper extends TermVectorMapper (Code)
For each Field, store position by position information. It ignores frequency information

This is not thread-safe.


Inner Class :public static class TVPositionInfo


Constructor Summary
public  PositionBasedTermVectorMapper()
    
public  PositionBasedTermVectorMapper(boolean ignoringOffsets)
    

Method Summary
public  MapgetFieldToTerms()
     Get the mapping between fields and terms, sorted by the comparator A map between field names and a Map.
public  booleanisIgnoringPositions()
     Never ignores positions.
public  voidmap(String term, int frequency, TermVectorOffsetInfo[] offsets, int[] positions)
     Callback for the TermVectorReader.
public  voidsetExpectations(String field, int numTerms, boolean storeOffsets, boolean storePositions)
    


Constructor Detail
PositionBasedTermVectorMapper
public PositionBasedTermVectorMapper()(Code)



PositionBasedTermVectorMapper
public PositionBasedTermVectorMapper(boolean ignoringOffsets)(Code)




Method Detail
getFieldToTerms
public Map getFieldToTerms()(Code)
Get the mapping between fields and terms, sorted by the comparator A map between field names and a Map. The sub-Map key is the position as the integer, the value is org.apache.lucene.index.PositionBasedTermVectorMapper.TVPositionInfo.



isIgnoringPositions
public boolean isIgnoringPositions()(Code)
Never ignores positions. This mapper doesn't make much sense unless there are positions false



map
public void map(String term, int frequency, TermVectorOffsetInfo[] offsets, int[] positions)(Code)
Callback for the TermVectorReader.
Parameters:
  term -
Parameters:
  frequency -
Parameters:
  offsets -
Parameters:
  positions -



setExpectations
public void setExpectations(String field, int numTerms, boolean storeOffsets, boolean storePositions)(Code)
Callback mechanism used by the TermVectorReader
Parameters:
  field - The field being read
Parameters:
  numTerms - The number of terms in the vector
Parameters:
  storeOffsets - Whether offsets are available
Parameters:
  storePositions - Whether positions are available
