public abstract 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:
- FieldsConsumer is created by
PostingsFormat.fieldsConsumer(SegmentWriteState)
.
- For each field,
addField(FieldInfo)
is called,
returning a TermsConsumer
for the field.
- After all fields are added, the consumer is
close()
d.
- WARNING: This API is experimental and might change in incompatible ways in the next release.
