Detailed Description

Make the difference of 2 regions.

Intended use:

Public interface

Prerequisite

LCRegion

Synopsis

The LCDifference class is a specialization of class LCRegion . It makes it possible to "subtract" one region from another. For example, imagine an overlapping box and circle. The box - circle is the box with the chunk taken out of it where the circle overlaps. The circle - box is the circle with the chunk taken out of it where the box overlaps.

The center of the difference must be inside the lattice

Constructor & Destructor Documentation

casa::LCDifference::LCDifference ( )

casa::LCDifference::LCDifference	(	const LCRegion &	region1,
		const LCRegion &	region2
	)

Construct the difference region1 - region2.

casa::LCDifference::LCDifference	(	Bool	takeOver,
		const PtrBlock< const LCRegion * > &	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.

casa::LCDifference::LCDifference ( const LCDifference & other )

Copy constructor (copy semantics).

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

Member Function Documentation

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

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

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

Make a copy of the derived object.

Implements casa::LCRegion.

void casa::LCDifference::defineBox ( ) [private]

Make the bounding box and determine the offsets.

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