Interface PilarDriver

All Superinterfaces:

DerotatorAccessible, Driver, FocusAccessible, Initializable, OffsetAccessible, ParameterDepending, PointingAccessible, TelescopeDriver

All Known Implementing Classes:

AbstractPilarDriver, OpenPilarSocket, OpenPilarSocket.PilarTest, Pilar3Socket, Pilar3Socket.PilarTest

public interface PilarDriver
extends TelescopeDriver, ParameterDepending

This interface describes a translation layer from TelescopeCommands to TCS commands. It defines all necessarry methods that allow the TelescopeMaster to communicate to the telescope. The interface definitions are closely bound to the SCS command structure and support only a subset of available TCS structures. All methods return true if successful.

Method Summary

Modifier and Type	Method and Description
boolean	commenceClear() Clears all errors the telescope.
boolean	commenceSetCovers(boolean close) Sets the position of the mirror covers.
boolean	commenceUsePort(int portnumber) Uses the specified port, i.e.
Collection<TsiError>	getErrors() Gets the current errors at the telescope.
Object	getValue(String name) Synchroniously return a value of a variable.
void	rebuild() Rebuild the error data base like on a restart.
boolean	setValue(String name, String to) Synchroniously return a value of a variable.
boolean	waitForValue(String variable, String value, String notvalue, long timeout) Waits for a parameter to achieve a certain value.

Method Detail

getValue

Object getValue(String name)
         throws IOException,
                TsiTimeoutException

Synchroniously return a value of a variable. Return type is object, but might be cast from calling methods to appropriate types.

Throws:

IOException

TsiTimeoutException

setValue

boolean setValue(String name,
                 String to)
          throws IOException,
                 TsiTimeoutException

Synchroniously return a value of a variable. Return type is object, but might be cast from calling methods to appropriate types.

Throws:

IOException

TsiTimeoutException

waitForValue

boolean waitForValue(String variable,
                     String value,
                     String notvalue,
                     long timeout)
              throws TsiTimeoutException,
                     IOException

Waits for a parameter to achieve a certain value. Blocks until either the true or the false value is achieved. If non of this conditions happen within the time-out, an exception is thrown.

Parameters:

variable - TSI parameter to query.

value - True value if given.

notvalue - False value if given.

timeout - Maximum block time in ms.

Throws:

TsiTimeoutException

IOException

rebuild

void rebuild()
      throws IOException,
             TsiTimeoutException

Rebuild the error data base like on a restart.

Throws:

IOException

TsiTimeoutException

getErrors

Collection<TsiError> getErrors()
                        throws IOException,
                               TsiTimeoutException

Gets the current errors at the telescope.

Throws:

IOException

TsiTimeoutException

commenceSetCovers

boolean commenceSetCovers(boolean close)
                   throws IOException,
                          TsiTimeoutException

Sets the position of the mirror covers.

Parameters:

close - true for closeing, false for opening.

Throws:

IOException

TsiTimeoutException

commenceClear

boolean commenceClear()
               throws IOException,
                      TsiTimeoutException

Clears all errors the telescope.

Throws:

IOException

TsiTimeoutException

commenceUsePort

boolean commenceUsePort(int portnumber)
                 throws IOException,
                        TsiTimeoutException

Uses the specified port, i.e. the Nashmith focus.

Parameters:

portnumber - Implementation specific configuration index.

Throws:

IOException

TsiTimeoutException
