Detailed Description

Base class for compound WCRegion objects.

Intended use:

Internal

Prerequisite

WCRegion

Synopsis

WCCompound is the base class for world coordinate regions. It defines the functionality simply as conversion to an LCRegion. This is because you need an LCRegion to be able to access the pixels in a Lattice.

The conversion functions should be flexible in that the supplied CoordinateSystem does not have to be the same as that with which the derived class was constructed. This means that you can apply a WCCompound from one image to another, provided that operation has some meaning.

Constructor & Destructor Documentation

casacore::WCCompound::WCCompound	(	const ImageRegion &	region1,
		const ImageRegion &	region2
	)

Construct from one or more image regions.

The image regions have to contain WCRegion objects, otherwise an exception is thrown.

casacore::WCCompound::WCCompound	(	const ImageRegion *	region1,
		const ImageRegion *	region2 = `0`,
		const ImageRegion *	region3 = `0`,
		const ImageRegion *	region4 = `0`,
		const ImageRegion *	region5 = `0`,
		const ImageRegion *	region6 = `0`,
		const ImageRegion *	region7 = `0`,
		const ImageRegion *	region8 = `0`,
		const ImageRegion *	region9 = `0`,
		const ImageRegion *	region10 = `0`
	)

casacore::WCCompound::WCCompound ( const PtrBlock< const ImageRegion * > & regions )

casacore::WCCompound::WCCompound	(	Bool	takeOver,
		const PtrBlock< const WCRegion * > &	regions
	)

Construct from multiple regions given as a Block.

When takeOver is True, the destructor will delete the given regions. Otherwise a copy of the regions is made.

casacore::WCCompound::WCCompound ( const WCCompound & other )

Copy constructor (copy semantics).

virtual casacore::WCCompound::~WCCompound ( )

virtual

Member Function Documentation

void casacore::WCCompound::init ( Bool takeOver )

private

Check if the regions are correct.

If needed, make a copy of the region objects.

TableRecord casacore::WCCompound::makeRecord ( const String & tableName ) const

protected

Store the contributing regions in a record.

void casacore::WCCompound::makeWCRegion ( const PtrBlock< const ImageRegion * > & )

private

Check if the ImageRegion's contain WCRegion's and extract them.

void casacore::WCCompound::multiToLCRegion	(	PtrBlock< const LCRegion * > &	regions,
		const CoordinateSystem &	cSys,
		const IPosition &	shape,
		const IPosition &	pixelAxesMap,
		const IPosition &	extendAxes
	)		const

protected

Convert each WCRegion to an LCRegion.

The axes argument tells which axes to use from the coordinate system and shape.

WCCompound& casacore::WCCompound::operator= ( const WCCompound & other )

protected

Assignment (copy semantics) makes only sense for a derived class.

virtual Bool casacore::WCCompound::operator== ( const WCRegion & other ) const

virtual

Comparison.

Reimplemented from casacore::WCRegion.

Reimplemented in casacore::WCConcatenation, casacore::WCUnion, casacore::WCIntersection, casacore::WCDifference, casacore::WCExtension, and casacore::WCComplement.

const PtrBlock< const WCRegion * > & casacore::WCCompound::regions ( ) const

inline

Get the contributing regions.
