Method Detail

perform

public <T extends Exception> void perform(SchedulerSessionUnitOfWork<T> uow)
                                   throws com.redwood.scheduler.api.exception.SchedulerAPIPersistenceException,

Execute a unit of work.

Parameters:

uow - The object to use to perform the work. Generic in the type of Exception its performWork method it throws. See SchedulerSessionUnitOfWork for the problems with using a raw type here.

Throws:

com.redwood.scheduler.api.exception.SchedulerAPIPersistenceException - if the persist fails maxretries times, then the last thrown exception will be rethrown

T - if the underlying unit of work throws an exception.

T extends Exception

perform

public <T extends Exception> void perform(SchedulerSessionUnitOfWork<T> uow,
                                          int maxRetries,
                                          int maxSpins)
                                   throws com.redwood.scheduler.api.exception.SchedulerAPIPersistenceException,
                                          T extends Exception

Execute a unit of work. If this thread is interrupted while a unit of work is underway, the unit of work proceeds until either completion or the number of retries is exhausted, at which point the most-recent persist() exception is thrown.

Parameters:

uow - The object to use to perform the work. Generic in the type of Exception its performWork method it throws. See SchedulerSessionUnitOfWork for the problems with using a raw type here.

maxRetries - The total number of times to retry.

maxSpins - The number of times to retry without pausing in between.

Throws:

com.redwood.scheduler.api.exception.SchedulerAPIPersistenceException - if the persist fails maxretries times, then the last thrown exception will be rethrown

T - if the underlying unit of work throws an exception.

T extends Exception
