java.lang.Object

io.deephaven.web.client.api.ReconnectState

public class ReconnectState
extends Object

Util class using exponential backoff to keep trying to connect to a server. Any disconnect should call failed(), and the given retry callback will be invoked as appropriate. Once connection is established, success() should be invoked to clear the reset tries attempted. Max backoff is doubled each failure, to a max of one minute. A random value between 0 and that backoff is selected to wait before trying again, to avoid clients all attempting to simultaneously reconnect. A maximum number of times to try can be specified, otherwise defaults to MAX_VALUE.
