Class BasicReconnectionManager

java.lang.Object

com.twitter.hbc.BasicReconnectionManager

All Implemented Interfaces:

ReconnectionManager

public class BasicReconnectionManager
extends Object
implements ReconnectionManager

This manages all of the reconnection logic. Mostly just keeps a bunch of information about whether we should reconnect at all, how much we should backfill, and how much to back off from connection failures.
