Method Summary

ThreadPoolExecutor	getBulkScheduler()
ScheduledExecutorService	getFixedSizeScheduler(int minimumThreads, String poolName)

Method Detail

getScheduler

DynamicSizedSchedulerInterface getScheduler(int minimumThreads,
                                            String poolName,
                                            int maximumPoolSize)

Request to get a scheduler with a minimum number of AVAILABLE threads.

Parameters:

minimumThreads - Minimum number of available threads for the returned scheduler

poolName - name of pool to identify threads

maximumPoolSize - maximum pool size

Returns:

A new scheduler that is ready to accept tasks

getFixedSizeScheduler

ScheduledExecutorService getFixedSizeScheduler(int minimumThreads,
                                               String poolName)

getTimeoutScheduler

ScheduledThreadPoolExecutor getTimeoutScheduler()

Default Timeout scheduler.

This is a one Thread fixed sized scheduler. This specific scheduler is using java 1.7 RemoveOnCancelPolicy, so the task are removed from queue permitting to avoid memory consumption [CONJ-297]

Returns:

A new scheduler that is ready to accept tasks

getBulkScheduler

ThreadPoolExecutor getBulkScheduler()
