Description
Interface Summary | |
---|---|
QueueScheduler<T> |
A QueueScheduler manages the time of the processing of
SchedulableQueueElement s in a queue using a
QueueSchedulingStrategy to calculate the
date when a queue element should be processed. |
QueueSchedulingContext<T> |
A QueueSchedulingContext - nome est omen -
provides a way to store and retrieve arbitrary parameters
in the context of a specifc queue scheduling process. |
QueueSchedulingStrategy<T> |
A QueueSchedulingStrategy encapsulates a concrete
policy on when to process a SchedulableQueueElement . |
SchedulableQueueElement<T> |
A SchedulableQueueElement represents an object that will
be processed in an arbitrary time based queueing mechanism. |
Class Summary | |
---|---|
ChainElement<T> |
A ChainElement is a part of a
QueueSchedulingStrategyChain and represents
some kind of an execution context. |
ChainFactory<T> |
A factory for QueueSchedulingStrategyChain s. |
ConstantQueueSchedulingStrategy<T> | ConstantQueueSchedulingStrategy will compute the next
schedule date by adding its intervalMillis to the current time which
will be retrieved by QueueScheduler.now() . |
DelayedLinearQueueSchedulingStrategy<T> |
The DelayedLinearQueueSchedulingStrategy represents a
two phase scheduling algorithm that reschedules queue elements
in their first phase in constant intervals and scales them
linearly with number of processings in their second. |
FixedQueueSchedulingStrategy<T> |
The FixedQueueSchedulingStrategy will "calculate" the
next processing date by just setting its fixed FixedQueueSchedulingStrategy.scheduleDate . |
LinearQueueSchedulingStrategy<T> |
LinearQueueSchedulingStrategy will compute the
next processing date by linearly scaling its
LinearQueueSchedulingStrategy.intervalMillis with the number of already happend
reschedulings thus resulting in a linear increase of
the intervals. |
QueueSchedulingContextImpl<T> | |
QueueSchedulings | Varios utility functions in the context of queue schedulings. |
QueueSchedulingStrategyChain<T> |
A QueueSchedulingStrategyChain implements a chain of
responsibility for queue scheduling strategies whilest being
a composited strategy itself and can be used to create
arbitrary, dynamic combinations of existing scheduling
algorithms. |
SchedulableQueueElementProxy<T> |
A proxy for SchedulableQueueElement s that allows
for some manipulations. |
Provides common classes to implement scheduling schemes. NOTE: this is highly experimental stuff!
