C# Класс Lucene.Net.Codecs.DocValuesConsumer

Abstract API that consumes numeric, binary and sorted docvalues. Concrete implementations of this actually do "something" with the docvalues (write it into the index in a specific format).

The lifecycle is:

  1. DocValuesConsumer is created by DocValuesFormat#fieldsConsumer(SegmentWriteState) or NormsFormat#normsConsumer(SegmentWriteState).
  2. #addNumericField, #addBinaryField, or #addSortedField are called for each Numeric, Binary, or Sorted docvalues field. The API is a "pull" rather than "push", and the implementation is free to iterate over the values multiple times (Iterable#iterator()).
  3. After all fields are added, the consumer is #closed.

Метод Описание
AddBinaryField ( FieldInfo field, IEnumerable values ) : void

Writes binary docvalues for a field.
AddNumericField ( FieldInfo field, IEnumerable values ) : void

Writes numeric docvalues for a field.
AddSortedField ( FieldInfo field, IEnumerable values, IEnumerable docToOrd ) : void

Writes pre-sorted binary docvalues for a field.
AddSortedSetField ( FieldInfo field, IEnumerable values, IEnumerable docToOrdCount, IEnumerable ords ) : void

Writes pre-sorted set docvalues for a field
Dispose ( ) : void
MergeBinaryField ( FieldInfo fieldInfo, MergeState mergeState, IList toMerge ) : void

Merges the binary docvalues from toMerge.

The default implementation calls #addBinaryField, passing an Iterable that merges and filters deleted documents on the fly.
MergeNumericField ( FieldInfo fieldInfo, MergeState mergeState, IList toMerge ) : void

Merges the numeric docvalues from toMerge.

The default implementation calls #addNumericField, passing an Iterable that merges and filters deleted documents on the fly.
MergeSortedField ( FieldInfo fieldInfo, MergeState mergeState, IList toMerge ) : void

Merges the sorted docvalues from toMerge.

The default implementation calls #addSortedField, passing an Iterable that merges ordinals and values and filters deleted documents .
MergeSortedSetField ( FieldInfo fieldInfo, MergeState mergeState, IList toMerge ) : void

Merges the sortedset docvalues from toMerge.

The default implementation calls #addSortedSetField, passing an Iterable that merges ordinals and values and filters deleted documents .
