Class FieldsConsumer

Abstract API that consumes terms, doc, freq, prox, offset and payloads postings. Concrete implementations of this actually do "something" with the postings (write it into the index in a specific format).

The lifecycle is:

  1. FieldsConsumer is created by FieldsConsumer(SegmentWriteState).
  2. For each field, AddField(FieldInfo) is called, returning a TermsConsumer for the field.
  3. After all fields are added, the consumer is Dispose()d.
