org.apache.cxf.management.web.logging.atom.deliverer.RetryingDeliverer

All Implemented Interfaces:

Deliverer

public final class RetryingDeliverer
extends Object
implements Deliverer

Wrapper on other deliverer retrying delivery in case of failure. Delivery attempts repeat in loop with some pause time between retries until successful delivery or exceeding time limit. Time delay between delivery is configurable strategy. Two predefined strategies are given: each time pause same amount of time (linear) and each next time pause time doubles (exponential).

Constructor Detail

RetryingDeliverer

public RetryingDeliverer(Deliverer worker,
                         int timeout,
                         int pause,
                         boolean linear)

Creates retrying deliverer with predefined retry strategy.

Parameters:

worker - real deliverer used to push data out.

timeout - maximum time range (in seconds) that retrial is continued; time spent on delivery call is included. No timeout (infinite loop) if set to zero.

pause - time of pause (in seconds) greater than zero.

linear - if true linear strategy (each time pause same amount of time), exponential otherwise (each next time pause time doubles).

Parameters:

worker - real deliverer used to push data out.

timeout - maximum time range (in seconds) that retrial is continued; time spent on delivery call is included. No timeout (infinite loop) if set to zero.

strategy - custom retry pausing strategy.
