Constructor Detail

DarkCcd

public DarkCcd(Object src)

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

DarkCcd

public DarkCcd(Object src,
               String type,
               long time)

Constructs a new exposure abort command. Per default no fits file is set.

Method Detail

registerTargetProperties

public void registerTargetProperties(Object setup)

Calculates the command line from the properties registered. Scans for the exposure time, ReservedConstants.EXPOSURETIME. Additionally, the fitsname-item, ReservedConstants.FITSNAME is looked up. If this key is present, a fits file name is generated according to FitsNameGenerator.getAbortFits(java.lang.String), otherwise the file name is set to null. A not-defined file name results in the data to be ereased.

Specified by:

registerTargetProperties in interface TargetDependingCommand

FitsNameGenerator

getLine

public String[] getLine()

Returns the command line of the dark ccd 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.

getExposureTime

public double getExposureTime()

Returns the exposure time asociated with the darktime command.

setExposureTime

private void setExposureTime(double to)

Sets the exposure time.

getExpectedAcknowledgeNumber

public int getExpectedAcknowledgeNumber()

Returns the number of acknowledge events this command is expected to follow. Used for test case only. If not overriden, this method will return one.

Overrides:

getExpectedAcknowledgeNumber in class CommandEvent

Returns:

Three.
