All Implemented Interfaces:

ITimeoutAlgorithm, ITriggerPropertiesKeys, java.io.Serializable

public class ConstantTimeoutAlgorithm

extends AbstractTimeoutAlgorithm

implements java.io.Serializable, ITriggerPropertiesKeys

This class implements a timeout algorithm that always returns the same value. The configuration for the timeout when the default constructor is used is obtained from the TriggerProperties object.

Constructor Detail

ConstantTimeoutAlgorithm

public ConstantTimeoutAlgorithm()

Constructor.

ConstantTimeoutAlgorithm

public ConstantTimeoutAlgorithm(long lTimeout,
                                int iRetries)

Constructor.

Parameters:

lTimeout - the timeout to use

iRetries - the maximum number of retries

Method Detail

getNextTimeout

public long getNextTimeout(long lInitialTimeout,
                           int iRetries,
                           long lLastTimeout)

Get the next timeout to use. If an initial timeout is specified this method is not called the first time.

Overrides:

getNextTimeout in class AbstractTimeoutAlgorithm

Parameters:

lInitialTimeout - the initial timeout that was used (-1 for no initial)

iRetryNumber - the current retry number

lLastTimeout - the last timeout that was used

Returns:

the next timeout, or -1 if no more retries (in milliseconds)
