public class CalibrationSimulator
extends GenericSimulator

Simulates the action of the adapter.

• Throws out-of command errors like DropTarget, LostGuiding, LostTarget, NoCalibration, NoFlatField, NoGuiding, and RegainedGuiding. LostGuiding may only be issued if adapter is in guiding mode, after a StartGuidingAdapter and guiding is not already lost. LostTarget may be issued if adapter is in guiding mode, regardless if it lost guiding, but only if target was not already lost. DropTarget is issued in a lost-guiding or lost-target situation. RegainedGuiding is only issued after guiding or target has been lost. The other three errors may be issued at any time. To allow testing of the call-back query (if the adapter needs the telescope azimuth), a special error is introduced RequestTelescopePosition. This error is scheduled out of the command cycle and captured in the isAllowed(stella.ErrorEvent) method in a way that during guiding the remote paramters are queried and the values retrieved are stored locally (for status commands). For this error, isAllowed(stella.ErrorEvent) always returns false, because it is not a regular error that should be thrown at any time.
• Understands the AcquireAdapter, CalibrationOnAdapter, CalibrationOffAdapter, ExposeAdapter, FindAdapter, FlatFieldOnAdapter, FlatFieldOffAdapter, InitAdapter, ParkAdapter, SelectFilterAdapter, StartGuidingAdapter, StopGuidingAdapter, and StatusAdapter commands. See processCommand(stella.CommandEvent, int) for details.
• The number of acknowledge messages sent back equals the CommandEvent.getExpectedAcknowledgeNumber().
• No remote parameters are supported, but the telescope altitude and azimuth and also the focus position must be rmi-accessible..

Constructor Detail

CalibrationSimulator

public CalibrationSimulator(Map prop)
                     throws RemoteException

Constructs a new adapter simulator. Does not serve any remote triggers. For details of command processing, see processCommand(stella.CommandEvent, int).

Throws:

RemoteException

Method Detail

initStep

public void initStep(int curstep)

We delay the initialization of the remote values to the last stages of the intialization to avoid blocking.

Specified by:

initStep in interface StepInitializable

Overrides:

initStep in class GenericSimulator

Parameters:

curstep - The current initialization depth.

init5

private void init5()

We delay the initialization of the remote values to the last stages of the intialization to avoid blocking.

myAugment

private static Map myAugment(Map def)

Augmentes the properties for the acknowledge, done, and divert times.

accepts

public boolean accepts(CommandEvent ce)
                throws RemoteException

Returns true if this receiver accepts commands of the type handed over as an argument. An adapter simulator accepts all sort of AdapterCommands.

Throws:

RemoteException

isAllowed

protected boolean isAllowed(ErrorEvent ee)

Returns true if the error handed over is allowed. The following things are checked:

• The NoCalibration, NoFlatField, and NoGuiding errors are always allowed.
• The LostGuiding error is allowed, if the adapter is guiding (#guide, and if guiding or the target have not already been lost (#lostguide, #losttarget).
• The LostTarget error is allowed, if the adapter is guiding (#guide, and if the target has not been lost. Different to LostGuiding it is also allowed if the guiding has been lost.
• DropTarget is allowed only if at least the guiding or, this reflects the more realistic case, the the target was lost. In the simulator, no distinction is made between allowence after lost guiding or lost target.
• RegainedGuiding is allowed only if the target or the guiding has been lost.
• The special error RequestTelescopePosition, which is a error only used during simulation, will always return false (so that it is not transported to an error handler, but will spark a remote-retrieval of the telescope position.

Specified by:

isAllowed in class GenericSimulator

getLastError

protected ErrorEvent getLastError()

Returns the last error that occured during command processing.

Specified by:

getLastError in class ReceiverTorso

getCompletionTime

protected long getCompletionTime(CommandEvent ce,
                                 int acknr)

Returns the completion time. If the command is a ExposeAdapter command and the acknowledge number is zero, add the distorted exposure time carried by the command to the value returned by the parental method.

Overrides:

getCompletionTime in class GenericSimulator

Parameters:

ce - The command to process.

acknr - The number of the acknowledge that will be sent back.

getSimulationTime

protected long getSimulationTime(CommandEvent ce,
                                 int acknr)

Returns the simulation time. If the command is a ExposeAdapter command and the acknowledge number is zero, add the distorted exposure time carried by the command to the value returned by the parental method.

Overrides:

getSimulationTime in class GenericSimulator

processCommand

protected boolean processCommand(CommandEvent ce,
                                 int acknr)

Simulates execution of the adapter commands. The following commands are served and their possible consequences indicated:

• AcquireAdapter: This command is issued when the adapter should acquire a target star. It therefore compares a list of field-of-view stars provided with the FindAdapter command with the current field-of-view obtained by the guiding ccd. Failure is possible in quite a bunch of ways: A NoGuiding error might be thrown, #KEY_FAILGUIDE. This error is also command-cycle independent. Additionally, a NoStarOnAcquire error might be thrown #KEY_FAILSTAR. This error might occur rather frequently, it is an indication of cloud coverage. Then, an AmbiguousStarPattern might occur if the star constellation found does not coincide with the field-of-view stars transfered in the FindAdapter command, probability #KEY_FAILAMBIGUOUS. Last but not least, a TargetStarMagnitude status event might be issued (#KEY_MAGNITUDE), if the target star was found, but its brightness is well of the expected value. This status event is intended for identifying acquiring difficulties and will not block target acquisition.
• CalibrationOnAdapter: Fails with KEY_FAILCALIBRATION to a NoCalibration. This error may also occur out-of-cycle.
• CalibrationOffAdapter: Never fails.
• ExposeAdapter: Sends back a AdapterFwhm status message. To allow focus groups to be tested, the current focus position is queried via RMI in the #focus value. Depending on #KEY_FOCUSOPTIMUM and #KEY_FOCUSFWHM together with #KEY_FOCUSDIVERT an artificial FWHM of the star image is calculated and sent back to the SCS.
• FindAdapter Never fails.
• FlatFieldOnAdapter Fails with KEY_FAILFLATFIELD to a NoFlatField. This error may also occur out-of-cycle.
• FlatFieldOffAdapter never fails.
• InitAdapter Fails with a #KEY_FAILINIT probability to a CannotInitAdapter.
• ParkAdapter never fails.
• SelectFilterAdapter Fails with a KEY_FAILFILTERPRESENT to a NoSuchFilter. Additionally can throw a NoFilterWheel (KEY_FAILFILTERSTUCK).
• StartGuidingAdapter Fails with #KEY_FAILGUIDE to a NoStarOnAcquire.
• StopGuidingAdapter never fails.
• StatusAdapter sends back an artificial status command, as right now no parameter is coupled to this status event.

Overrides:

processCommand in class GenericSimulator
