Class AncillaryFileManager

Object

AncillaryFileManager

All Implemented Interfaces:

FileSetManager

public class AncillaryFileManager
extends Object
implements FileSetManager

A class used to store any auxiliary indexing information such as the low level indexer definition as well as the datastore properties configuration specifying where to build that index.

Since 14.x is it also possible to store the catalog into a PostGis based DB
