Class TelescopeAccess

util.CommandLineParser

stella.rmi.GenericAccess

stella.telescope.TelescopeAccess

public class TelescopeAccess
extends GenericAccess

A small program allowing access to TelescopeControlling enhanced objects. The command line arguments are scanned for recognized switches and processed accordingly. Additionally to the functionality of the parent class ShiftListener, this class supports the following switches:

• -a: Enables automatic ccd control. If the ccd is actually controlled by a non-automatic command caster, e.g. a stella.jview.JLaunchBox, this caster should be deregistered before enabling automatic mode. In automatic mode, only the status retrieval and setting the manual mode is supported.
• -m: Disables automatic roof control, i.e. shifts to a manual mode. Control with a non-automatic command caster, e.g. a stella.jview.JLaunchBox, requires additionally a registering at the new caster. Only in manual mode, all of the further actions are allowed.
• -s: Returns the status of the ccd camera.
• -q: Quits the building controling instance.

Constructor Detail

TelescopeAccess

public TelescopeAccess()

Constructs a new camera access instance. The switches understood are readily added to the command line parser.

Method Detail

processSwitches

protected boolean processSwitches(Remote listener)
                           throws RemoteException

Process the command line switches found. If the remote reference handed over is a SesControlling and one of the switches defined in ZEROSWITCHES, ONESWITCHES, TWOSWITCHES, #THREESWITCHES, or #SIXSWITCHES is given, the appropriate method of the listener control is called. Note that the command line must be parsed before calling this method.
Implementation note: Prior to the new command line switches, the one provided by the parent class are processed.

Overrides:

processSwitches in class GenericAccess

Returns:

True on success.

Throws:
