Specified by:

addNumericField in class DocValuesConsumer

Parameters:

field - field information

values - Iterable of numeric values (one for each document). null indicates a missing value.

Throws:

java.io.IOException - if an I/O error occurred.

addBinaryField

public void addBinaryField(FieldInfo field,
                           java.lang.Iterable<BytesRef> values)
                    throws java.io.IOException

Description copied from class: DocValuesConsumer

Writes binary docvalues for a field.

Specified by:

addBinaryField in class DocValuesConsumer

Parameters:

field - field information

values - Iterable of binary values (one for each document). null indicates a missing value.

Throws:

java.io.IOException - if an I/O error occurred.

addSortedField

public void addSortedField(FieldInfo field,
                           java.lang.Iterable<BytesRef> values,
                           java.lang.Iterable<java.lang.Number> docToOrd)
                    throws java.io.IOException

Description copied from class: DocValuesConsumer

Specified by:

addSortedField in class DocValuesConsumer

Parameters:

field - field information

values - Iterable of binary values in sorted order (deduplicated).

docToOrd - Iterable of ordinals (one for each document). -1 indicates a missing value.

Throws:

java.io.IOException - if an I/O error occurred.

addSortedNumericField

public void addSortedNumericField(FieldInfo field,
                                  java.lang.Iterable<java.lang.Number> docToValueCount,
