Field Detail

fits

private File fits

The fits file where to save the ccd data in.

wasabort

private boolean wasabort

The result of the parameter query.

Constructor Detail

ExposureAbortCcd

public ExposureAbortCcd(Object src)

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

ExposureAbortCcd

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

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

Method Detail

registerParameter

public void registerParameter(Parameter abort)

Checks if the parameter handed over is a Trigger. If so, its value is stored in the wasabort field and defines the fits-file name transported with this command.
This only works because the parameter is registered prior to the target.

Specified by:

registerParameter in interface ParameterDepending

registerTargetProperties

public void registerTargetProperties(Object setup)

Calculates the command line from the properties registered. Scans for the fitsname-item, ReservedConstants.FITSNAME. 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 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.

getFits

public File getFits()

Returns the fits file asociated with the abort command.

Specified by:

getFits in interface FileCarrying

setFits

private void setFits(File to)

Sets the fits file name.

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.
