	)		[explicit]

Construct a FITSImage from the disk FITS file name and extension and apply mask.

casa::FITSErrorImage::FITSErrorImage	(	const String &	name,
		const MaskSpecifier &	mask,
		uInt	whichRep = 0,
		uInt	whichHDU = 0,
		FITSErrorImage::ErrorType	errtype = MSE
	)

Construct a FITSImage from the disk FITS file name and extension and apply mask or not.

Member Function Documentation

virtual ImageInterface<Float>* casa::FITSErrorImage::cloneII

(

)

const [virtual]

Make a copy of the object with new (reference semantics).

Reimplemented from casa::FITSImage.

virtual Bool casa::FITSErrorImage::doGetSlice	(	Array< Float > &	buffer,
		const Slicer &	theSlice
	)		[virtual]

Do the actual get of the data.

Returns False as the data do not reference another Array

Reimplemented from casa::FITSImage.

virtual void casa::FITSErrorImage::doPutSlice	(	const Array< Float > &	sourceBuffer,
		const IPosition &	where,
		const IPosition &	stride
	)		[virtual]

The FITSImage is not writable, so this throws an exception.

Reimplemented from casa::FITSImage.

virtual FITSErrorImage::ErrorType casa::FITSErrorImage::errorType

(

)

const [inline, virtual]

Return the error type.

Definition at line 125 of file FITSErrorImage.h.

static String casa::FITSErrorImage::errorTypeToString

(

FITSErrorImage::ErrorType

errType

)

[static]

Convert a String to an image type.

virtual String casa::FITSErrorImage::imageType

(

Assignment (reference semantics)

void casa::FITSErrorImage::setupMask

(

)

[private]

Set the correct masking.

static FITSErrorImage::ErrorType casa::FITSErrorImage::stringToErrorType

(

String

errorTypeStr

)

[static]

Convert an image type to String.
