Constructor Summary

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

FocusTelescope(Object src, String id, long time)
Constructs a new focus telescope command.

Method Summary

String[]	getLine() Returns the command line of the move telescope command.
double	getPosition() Returns the right ascension of the target star.
void	initWith(String focus) If initialized with a parsable double, this gets the focus offset.
boolean	parseLine(String[] all) Parse the command line into a focus position.
void	registerParameter(Parameter focus) Registers an parameter set to this command.
void	setPosition(double pos) Sets the focus position.

Constructor Detail

FocusTelescope

public FocusTelescope(Object src)

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

FocusTelescope

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

Constructs a new focus telescope command. The command only gets valid either by calling the parseLine(java.lang.String[]) method or by registering an XML-Element to it.

Method Detail

initWith

public void initWith(String focus)

If initialized with a parsable double, this gets the focus offset.

Specified by:

initWith in interface InitializerDepending

registerParameter

public void registerParameter(Parameter focus)

Registers an parameter set to this command. The parameter handed over is queried for its current value and this focus position is set.

Specified by:

registerParameter in interface ParameterDepending

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 a focus position. The first array element is parsed into a double.

Specified by:

parseLine in class MessageEvent

Returns:

True, if parsing was successful.

getPosition

public double getPosition()

Returns the right ascension of the target star.

setPosition

public void setPosition(double pos)

Sets the focus position.
