PARENT CLASS

mswCHANGE_FOCUS

DESCRIPTION

Performs focus change.
This subclass implements the real focus changing functionality taking
into account the specific telescope architecture for VLT.

PUBLIC METHODS

mswCHANGE_FOCUS_VLT(mswMOD_LIST_MANAGER &listManager);
mswCHANGE_FOCUS_VLT(const dbSYMADDRESS  dbPoint,
                       mswMOD_LIST_MANAGER &listManager);
  Two constructors are provided.
  The second one receives as parameter the symbolic address of
  online database support point for the object, i.e. the point
  where the object can find configuration and run time values.
  The first one defines the online database support point calling
  the standard tcsDbRoot(4) function and appenting the
  default relative path from the TCS database root point,
  assuming a complete default TCS database structure.
  It calls the parent class' constructor.

~mswCHANGE_FOCUS_VLT()

ccsCOMPL_STAT  Execute(msgMESSAGE     &msg);

  Starts the real execution of the change focus procedure.
  It sends the command sequence:
  - STPWAIT to AO
  - STOP    to FS
  - STOPCHP to M2
  - ....... to ..
  The procedure sequence is controlled by the two callbacks
  <xx><Cmd>OkCB and <xx><Cmd>ErrorCB. The <xx><Cmd>OkCB
  sends the next command.

PROTECTED METHODS

 virtual evhCB_COMPL_STAT  <xx><Cmd>OkCB(msgMESSAGE &msg,
                                         void *udata);

   This callback is attached to the command object used
   to send commands to <xx>. It gets the control after every
   successfull completion of the command (last OK reply received),
   and starts the next step.
   When the last step of the procedure has been completed,
   it returns the control flow to the mswCONTROL_MAIN object.

 virtual evhCB_COMPL_STAT  <xx><Cmd>ErrorCB(msgMESSAGE &msg,
                                            vltLOGICAL timeoutFlag);

   This callback is attached to the command object used
   to send commands to <xx>. It gets the control when an error
   or timeout reply is received. It handles the error, stops
   the execution of the procedure and return the control flow
   to the mswCONTROL_MAIN object.
