java.lang.Objectde.grogra.xl.impl.queues.QueueCollection
public final class QueueCollection
A QueueCollection
represents a set of
Queue
s in the context of a
Graph
.
For the base implementation of the XL interfaces, it is obtained
at run-time by the invocation of
Graph.getQueues()
.
Queues are added to this collection by invocation of
getQueue(QueueDescriptor)
.

All queues which have been registered by
getQueue(QueueDescriptor)
are processed. The order of
processing is defined by the QueueDescriptor
s of the queues:
If q
and r
are two queues having descriptors
Q
and R
, then
q.process(segments)
may be invoked before r.process(segments)
only if Q is not contained in R.queuesToProcessAfter()
and R is not contained in Q.queuesToProcessBefore()
.
After all queues have been processed, this method clears the queues.
