FieldsConsumer (The Adobe Experience Manager SDK 2022.11.9850.20221116T162329Z-220900)

java.lang.Object
- org.apache.lucene.codecs.FieldsConsumer

All Implemented Interfaces:

java.io.Closeable, java.lang.AutoCloseable

Direct Known Subclasses:

BlockTreeTermsWriter
```
public abstract class FieldsConsumer
extends java.lang.Object
implements java.io.Closeable
```
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 PostingsFormat.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 close()d.

           throws java.io.IOException
```
    Called during merging to merge all Fields from sub-readers. This must recurse to merge all postings (terms, docs, positions, etc.). A PostingsFormat can override this default implementation to do its own merging.
