PrefixCodedTerms (Lucene 9.3.0 core API)

java.lang.Object
- org.apache.lucene.index.PrefixCodedTerms

All Implemented Interfaces:

Accountable
```
public class PrefixCodedTerms
extends Object
implements Accountable
```
Prefix codes term instances (prefixes are shared). This is expected to be faster to build than a FST and might also be more compact if there are no common suffixes.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.
