Class TableManager

java.lang.Object

org.gorpipe.gor.manager.TableManager

public class TableManager
extends java.lang.Object

Class to manage gor tables (dictionaries and tables).

Includes commands to:

load table insert entries into table delete entries from table select bucketize remove entries from buckets delete buckets

TODO: Why not move bucketize methods into the DictionaryTable object. TODO: bucketzationInfo should be part of the table and stored in the table header (only passed in when table is created). Use sensible defaults otherwise.
