All Implemented Interfaces:

Serializable, TelescopeCommand

public class OffsetTest
extends CommandEvent
implements TelescopeCommand

A test command to offset the telescope for a random amount. The offset is a gaussian-distributed value scaled to MAXAZOFFSET and MAXALTOFFSET.

Constructor Summary

OffsetTest(Object src)
Constructs a abort adapter telescope, grabbing the type from the class name and setting the command time to the current system time.

OffsetTest(Object src, String id, long time)
Constructs a new offset telescope command.

Method Summary

String[]	getLine() Returns the command line of the move telescope command.
double	getOffsetAltitude() Returns the y-offset of the target star.
double	getOffsetAzimuth() Returns the x-offset of the target star.
String	getType() Fake the type to be of OFFSET_TELESCOPE.
boolean	parseLine(String[] all) Parse the command line into ra and dec of the move command.
void	setOffset(double xoff, double yoff) Sets the offsets in x and y.

Constructor Detail

OffsetTest

public OffsetTest(Object src)

Constructs a abort adapter telescope, grabbing the type from the class name and setting the command time to the current system time.

OffsetTest

public OffsetTest(Object src,
                  String id,
                  long time)

Constructs a new offset telescope command. The command only gets valid when either its parseLine(java.lang.String[]) or the setOffset(double, double) method are called.
To mark both offsets invalid, NaN is assigned to them.

Method Detail

getLine

public String[] getLine()

Returns the command line of the move telescope command.

Specified by:

getLine in class MessageEvent

Returns:

An array containing all command lines.

parseLine

public boolean parseLine(String[] all)

Parse the command line into ra and dec of the move command.

Specified by:

parseLine in class MessageEvent

Returns:

True, if parsing was successful.

setOffset

public void setOffset(double xoff,
                      double yoff)

Sets the offsets in x and y. The offsets are pixels on the CCD, divided by the scale factor of the guiding CCD.

getOffsetAzimuth

public double getOffsetAzimuth()

Returns the x-offset of the target star. If the command is invalid, NaN is returned.

getOffsetAltitude

public double getOffsetAltitude()

Returns the y-offset of the target star. If the command is invalid, NaN is returned.

getType

public String getType()

Fake the type to be of OFFSET_TELESCOPE.

Overrides:

getType in class MessageEvent
