public class HashSetBackedTableFactory
extends Object

An abstract table that represents a hashset of smart keys. Since we are representing a set, there we are not defining an order to our output. Whatever order the table happens to end up in, is fine. The table will refresh by regenerating the full hashset (using the setGenerator Function passed in); and then comparing that to the existing hash set.

 String... colNames)

Create a ticking table based on a setGenerator.

Parameters:

setGenerator - a function that returns a HashSet of SmartKeys, each SmartKey is a row in the output.

refreshIntervalMs - how often to refresh the table, if less than or equal to 0 the table does not tick.

colNames - the column names for the output table, must match the number of elements in each SmartKey.

Returns:
