Method Details

addNumericField

public void addNumericField(FieldInfo field,
 DocValuesProducer valuesProducer)
                     throws IOException

Description copied from class: DocValuesConsumer

Writes numeric docvalues for a field.

Specified by:

addNumericField in class DocValuesConsumer

Parameters:

field - field information

valuesProducer - Numeric values to write.

Throws:

IOException - if an I/O error occurred.

addBinaryField

public void addBinaryField(FieldInfo field,
 DocValuesProducer valuesProducer)
                    throws IOException

Description copied from class: DocValuesConsumer

Writes binary docvalues for a field.

Specified by:

addBinaryField in class DocValuesConsumer

Parameters:

field - field information

valuesProducer - Binary values to write.

Throws:

IOException - if an I/O error occurred.

addSortedField

public void addSortedField(FieldInfo field,
 DocValuesProducer valuesProducer)
                    throws IOException

Description copied from class: DocValuesConsumer

Writes pre-sorted binary docvalues for a field.

Specified by:

addSortedField in class DocValuesConsumer

Parameters:

field - field information

valuesProducer - produces the values and ordinals to write

Throws:

IOException - if an I/O error occurred.

addSortedNumericField

public void addSortedNumericField(FieldInfo field,
 DocValuesProducer valuesProducer)
                           throws IOException

Description copied from class: DocValuesConsumer

Writes pre-sorted numeric docvalues for a field

Specified by:

addSortedNumericField in class DocValuesConsumer

Parameters:

field - field information

valuesProducer - produces the values to write

Throws:

IOException - if an I/O error occurred.

addSortedSetField

public void addSortedSetField(FieldInfo field,
 DocValuesProducer valuesProducer)
                       throws IOException

Description copied from class: DocValuesConsumer

Writes pre-sorted set docvalues for a field

Specified by:

addSortedSetField in class DocValuesConsumer

Parameters:

field - field information

valuesProducer - produces the values to write

Throws:

IOException - if an I/O error occurred.

merge

public void merge(MergeState mergeState)
           throws IOException

Description copied from class: DocValuesConsumer

Merges in the fields from the readers in mergeState. The default implementation calls DocValuesConsumer.mergeNumericField(org.apache.lucene.index.FieldInfo, org.apache.lucene.index.MergeState), DocValuesConsumer.mergeBinaryField(org.apache.lucene.index.FieldInfo, org.apache.lucene.index.MergeState), DocValuesConsumer.mergeSortedField(org.apache.lucene.index.FieldInfo, org.apache.lucene.index.MergeState), DocValuesConsumer.mergeSortedSetField(org.apache.lucene.index.FieldInfo, org.apache.lucene.index.MergeState), or DocValuesConsumer.mergeSortedNumericField(org.apache.lucene.index.FieldInfo, org.apache.lucene.index.MergeState) for each field, depending on its type. Implementations can override this method for more sophisticated merging (bulk-byte copying, etc).

Overrides:

merge in class DocValuesConsumer

Throws:

IOException

getInstance

private DocValuesConsumer getInstance(FieldInfo field)
                               throws IOException

Throws:

IOException

getInstance

private DocValuesConsumer getInstance(FieldInfo field,
 boolean ignoreCurrentFormat)
                               throws IOException

DocValuesConsumer for the given field.

Parameters:

field - - FieldInfo object.

ignoreCurrentFormat - - ignore the existing format attributes.

Returns:

DocValuesConsumer for the field.

Throws:

IOException - if there is a low-level IO error

close

public void close()
           throws IOException

Throws:

IOException
