com.crankuptheamps.client.FixedDelayStrategy

All Implemented Interfaces:

ReconnectDelayStrategy

public class FixedDelayStrategy
extends java.lang.Object
implements ReconnectDelayStrategy

FixedDelayStrategy is an implementation that delays for a fixed time period, as specified in the constructor, when reconnecting to the same server as we were previously connected to, or if we are invoked again for the first server we ever tried.

Constructor Detail

FixedDelayStrategy

public FixedDelayStrategy()

Construct a FixedDelayStrategy with the default delay (200ms).

FixedDelayStrategy

public FixedDelayStrategy(int delay_)

Construct a FixedDelayStrategy with a specified delay.

Parameters:

delay_ - The delay (milliseconds) to be used between reconnect attempts to the same server.

FixedDelayStrategy

public FixedDelayStrategy(int delay_,
                          int maximum_)

Construct a FixedDelayStrategy with a specified delay and maximum.

Parameters:

delay_ - The delay (milliseconds) to be used between reconnect attempts to the same server.

maximum_ - The maximum time (milliseconds) to try connecting to servers before "giving up."

Method Detail

getConnectWaitDuration

public int getConnectWaitDuration(java.lang.String uri_)
                           throws java.lang.Exception

Returns the time (in milliseconds) that the client should wait before connecting to the given server URI.

Specified by:

getConnectWaitDuration in interface ReconnectDelayStrategy

Parameters:

uri_ - The URI to which the client intends to connect.

Returns:

Returns the time in milliseconds the client should delay before connecting to uri_.

Throws:

java.lang.Exception - Any exception thrown indicates no connection should be attempted.

reset

public void reset()

Resets the state of this delay. AMPS calls this method when a connection is successfully established.

Specified by:

reset in interface ReconnectDelayStrategy
