Method Summary public  void doWork(Work work)      Accepts a Work instance for processing. public  void doWork(Work work, long timeout, ExecutionContext executionContext, WorkListener workListener)      Accepts a Work instance for processing. public  int getCurrentPoolSize()      public  int getMaxPoolSize()      public  int getMinPoolSize()      public  void nextWork()      Do the next JWork object to be run. public  void scheduleWork(Work work)      Accepts a Work instance for processing. public  void scheduleWork(Work work, long timeout, ExecutionContext executionContext, WorkListener workListener)      Accepts a Work instance for processing. public  void setMaxPoolSize(int maxsz)      Sets the max pool size. public  void setMinPoolSize(int minsz)      Sets the min pool size. public  long startWork(Work work)      Accepts a Work instance for processing. public  long startWork(Work work, long timeout, ExecutionContext executionContext, WorkListener workListener)      Accepts a Work instance for processing. public synchronized  void stopThreads()      Remove this WorkManager : Stop all threads. Constructor Detail ResourceWorkManager public ResourceWorkManager(TransactionManager transactionManager, int minsz, int maxsz, long threadwait)(Code) Default Constructor. Parameters:   minsz - the minimum pool size Parameters:   maxsz - the maximum pool size Parameters:   transactionManager - the transaction manager to use. Parameters:   threadwait - max time in seconds a thread will wait. Method Detail doWork public void doWork(Work work) throws WorkRejectedException, WorkCompletedException, WorkException(Code) Accepts a Work instance for processing. This call blocks until the Work instance completes execution. There is no guarantee on when the accepted Work instance would start execution ie., there is no time constraint to start execution. Parameters:   work - The unit of work to be done. Could be long or short-lived. throws:   WorkRejectedException - a Work instance has been rejected fromfurther processing. throws:   WorkCompletedException - a Work instance has completed executionwith an exception. throws:   WorkException - if work is not done doWork public void doWork(Work work, long timeout, ExecutionContext executionContext, WorkListener workListener) throws WorkRejectedException, WorkCompletedException, WorkException(Code) Accepts a Work instance for processing. This call blocks until the Work instance completes execution. Parameters:   work - The unit of work to be done. Could be long or short-lived. Parameters:   timeout - a time duration (in milliseconds) within which theexecution of the Work instance must start. Otherwise, the Workinstance is rejected with a WorkRejectedException set to anappropriate error code (WorkRejectedException.TIMED_OUT). Parameters:   executionContext - an object containing the execution context withwhich the submitted Work instance must be executed. Parameters:   workListener - an object which would be notified when the variousWork processing events (work accepted, work rejected, workstarted, work completed) occur. throws:   WorkRejectedException - a Work instance has been rejected fromfurther processing. throws:   WorkCompletedException - a Work instance has completed executionwith an exception. throws:   WorkException - if work is not done getCurrentPoolSize public int getCurrentPoolSize()(Code) current pool size getMaxPoolSize public int getMaxPoolSize()(Code) max pool size getMinPoolSize public int getMinPoolSize()(Code) min pool size nextWork public void nextWork() throws WorkException, InterruptedException, ResourceWorkManagerStoppedException(Code) Do the next JWork object to be run. throws:   WorkException - if work is not done throws:   InterruptedException - if one object can't wait. throws:   ResourceWorkManagerStoppedException - if the manager is stopped. scheduleWork public void scheduleWork(Work work) throws WorkRejectedException, WorkException(Code) Accepts a Work instance for processing. This call does not block and returns immediately once a Work instance has been accepted for processing. There is no guarantee on when the submitted Work instance would start execution ie., there is no time constraint to start execution. Parameters:   work - The unit of work to be done. Could be long or short-lived. throws:   WorkRejectedException - - indicates that a Work instance has beenrejected from further processing. This can occur due to internalfactors. throws:   WorkException - if work is not scheduled. scheduleWork public void scheduleWork(Work work, long timeout, ExecutionContext executionContext, WorkListener workListener) throws WorkRejectedException, WorkException(Code) Accepts a Work instance for processing. This call does not block and returns immediately once a Work instance has been accepted for processing. There is no guarantee on when the submitted Work instance would start execution ie., there is no time constraint to start execution. Parameters:   work - The unit of work to be done. Could be long or short-lived. Parameters:   timeout - a time duration (in milliseconds) within which theexecution of the Work instance must start. Otherwise, the Workinstance is rejected with a WorkRejectedException set to anappropriate error code (WorkRejectedException.TIMED_OUT). Parameters:   executionContext - an object containing the execution context withwhich the submitted Work instance must be executed. Parameters:   workListener - an object which would be notified when the variousWork processing events (work accepted, work rejected, workstarted, work completed) occur. throws:   WorkRejectedException - a Work instance has been rejected fromfurther processing. throws:   WorkException - if work is not scheduled. setMaxPoolSize public void setMaxPoolSize(int maxsz)(Code) Sets the max pool size. Parameters:   maxsz - the max pool size. setMinPoolSize public void setMinPoolSize(int minsz)(Code) Sets the min pool size. Parameters:   minsz - the min pool size. startWork public long startWork(Work work) throws WorkRejectedException, WorkException(Code) Accepts a Work instance for processing. This call blocks until the Work instance starts execution but not until its completion. There is no guarantee on when the accepted Work instance would start execution ie., there is no time constraint to start execution. Parameters:   work - The unit of work to be done. Could be long or short-lived. the time elapsed (in milliseconds) from Work acceptance untilstart of execution. Note, this does not offer real-timeguarantees. It is valid to return -1, if the actual start delayduration is unknown. throws:   WorkRejectedException - a Work instance has been rejected fromfurther processing. throws:   WorkException - if work is not started startWork public long startWork(Work work, long timeout, ExecutionContext executionContext, WorkListener workListener) throws WorkRejectedException, WorkException(Code) Accepts a Work instance for processing. This call blocks until the Work instance starts execution but not until its completion. There is no guarantee on when the accepted Work instance would start execution ie., there is no time constraint to start execution. Parameters:   work - The unit of work to be done. Could be long or short-lived. Parameters:   timeout - a time duration (in milliseconds) within which theexecution of the Work instance must start. Otherwise, the Workinstance is rejected with a WorkRejectedException set to anappropriate error code (WorkRejectedException.TIMED_OUT). Parameters:   executionContext - an object containing the execution context withwhich the submitted Work instance must be executed. Parameters:   workListener - an object which would be notified when the variousWork processing events (work accepted, work rejected, workstarted, work completed) occur. the time elapsed (in milliseconds) from Work acceptance untilstart of execution. Note, this does not offer real-timeguarantees. It is valid to return -1, if the actual start delayduration is unknown. throws:   WorkRejectedException - a Work instance has been rejected fromfurther processing. throws:   WorkException - if work is not started stopThreads public synchronized void stopThreads()(Code) Remove this WorkManager : Stop all threads.
