Method Detail

newTask

protected void newTask(Task task_,
                       WorkerThread currentThread_)

The only way to trigger new tasks to be executed.

Specified by:

newTask in class ACARuntime

getThread

protected WorkerThread getThread()

Returns the current thread context.

Overrides:

getThread in class ACARuntime

info

public java.lang.String info()

Description copied from class: ACARuntime

Returns general information of this runtime.

Specified by:

info in class ACARuntime

ss_info

public java.lang.String ss_info()

Synchronized version of s_info().

s_info

public java.lang.String s_info()

getMainThread

public SEThreadOld getMainThread()

a_info

public java.lang.String a_info(boolean listWaitingTasks_)

Asynchronous version of ACARuntime.diag().

Specified by:

a_info in class ACARuntime

tasks

public java.lang.String tasks()

Returns information of the task queue.

forceReset

public void forceReset()

Forces to reset this runtime.

___PROFILE___

public void ___PROFILE___()

getNumberOfArrivalEvents

public long getNumberOfArrivalEvents()

Description copied from class: ACARuntime

Returns the number of arrival events.

Specified by:

getNumberOfArrivalEvents in class ACARuntime

getEventRate

public double getEventRate()

Description copied from class: ACARuntime

Returns the event processing rate of this runtime.

Specified by:

getEventRate in class ACARuntime

_getEventRate

protected double _getEventRate(long numArrivals_)

_getTime

protected double _getTime()

Asynchronized version of getTime(), for diagnosis.

Specified by:

_getTime in class ACARuntime

_stop

protected void _stop(boolean block_)

Specified by:

_stop in class ACARuntime

resume

public void resume()

Description copied from class: ACARuntime

Resumes the system. The state must advance to RUNNING when this method returns.

Specified by:

resume in class ACARuntime

reset

public void reset()

Description copied from class: ACARuntime

Specified by:

t_info in class ACARuntime

setState

protected void setState(java.lang.String new_)

Overrides:

setState in class ACARuntime

println

public void println(java.lang.String msg_)
