Interface IndexDictionary
- All Known Implementing Classes:
FSTDictionary
public interface IndexDictionary
Immutable stateless index dictionary kept in RAM.
Implementations must be immutable.
Use IndexDictionary.Builder to build the IndexDictionary.
Create a stateful IndexDictionary.Browser to seek a term in this IndexDictionary and get its corresponding block file pointer to the terms block file.
There is a single implementation of this interface, FSTDictionary. However this
interface allows you to plug easily a new kind of index dictionary to experiment and improve the
existing one.
- WARNING: This API is experimental and might change in incompatible ways in the next release.
