Constructor & Destructor Documentation

casa::LCBox::LCBox ( )

casa::LCBox::LCBox ( const IPosition & latticeShape ) [explicit]

Construct a box for the full lattice shape.

casa::LCBox::LCBox	(	const Slicer &	box,
		const IPosition &	latticeShape
	)

Construct from the Slicer defining the box.

The slicer may not contain a stride.

casa::LCBox::LCBox	(	const IPosition &	blc,
		const IPosition &	trc,
		const IPosition &	latticeShape
	)

Construct from the IPosition's defining the bottom-left and top-right corner of the box.

casa::LCBox::LCBox	(	const Vector< Float > &	blc,
		const Vector< Float > &	trc,
		const IPosition &	latticeShape
	)

Construct from the Vector's defining the bottom-left and top-right corner of the box.

casa::LCBox::LCBox	(	const Vector< Double > &	blc,
		const Vector< Double > &	trc,
		const IPosition &	latticeShape
	)

casa::LCBox::LCBox ( const LCBox & other )

Copy constructor (reference semantics).

virtual casa::LCBox::~LCBox ( ) [virtual]

Member Function Documentation

Vector< Float > casa::LCBox::blc ( ) const [inline]

Get the box blc.

Definition at line 156 of file LCBox.h.

References itsBlc.

static String casa::LCBox::className ( ) [static]

Get the class name (to store in the record).

virtual LCRegion* casa::LCBox::cloneRegion ( ) const [virtual]

Make a copy of the derived object.

Implements casa::LCRegion.

virtual LCRegion* casa::LCBox::doTranslate	(	const Vector< Float > &	translateVector,
		const IPosition &	newLatticeShape
	)			const `[protected, virtual]`

Construct another LCBox (for e.g.

another lattice) by moving this one. It recalculates the bounding box. A positive translation value indicates "to right".

Implements casa::LCRegion.

void casa::LCBox::fillBlcTrc ( ) [private]

Fill the blc and trc vector from IPositions.

static LCBox* casa::LCBox::fromRecord	(	const TableRecord &	,
		const String &	tablename
	)			`[static]`

Convert correct object from a record.

Reimplemented from casa::LCRegion.

LCBox& casa::LCBox::operator= ( const LCBox & other )

Assignment (copy semantics).

virtual Bool casa::LCBox::operator== ( const LCRegion & other ) const [virtual]

Comparison.

Mask not checked. Use function LRegionSingle::maskEqual to do this

Reimplemented from casa::LCRegionFixed.

void casa::LCBox::setSlicerBox	(	const IPosition &	blc,
		const IPosition &	trc
	)			`[private]`

Make a box from the blc,trc such that it does not exceed the lattice boundaries.

virtual TableRecord casa::LCBox::toRecord ( const String & tableName ) const [virtual]

Convert the (derived) object to a record.

Implements casa::LCRegion.

Vector< Float > casa::LCBox::trc ( ) const [inline]

Get the box trc.

Definition at line 160 of file LCBox.h.

References itsTrc.

virtual String casa::LCBox::type ( ) const [virtual]

Get the region type.

Returns className()

Implements casa::LCRegion.

static Bool casa::LCBox::verify	(	IPosition &	blc,
		IPosition &	trc,
		IPosition &	inc,
		const IPosition &	shape
	)			`[static]`

Verify a box specification.

Illegal (inlcuding blc > trc) or unspecified values are given 0 (blc) shape (trc) or unity (inc). Returns True if any of the blc/trc/inc are changed from their input values, else returns False
