Detailed Description

Make the intersection of 2 or more regions.

Intended use:

Public interface

Prerequisite

• LCRegion

Synopsis

The LCIntersection class is a specialization of class LCRegion . It makes it possible to find the intersection of given regions.

The center of the intersection must be inside the lattice

Example

To Do

• Expand along (slanted) cone lines

Constructor & Destructor Documentation

casa::LCIntersection::LCIntersection

(

)

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

Construct the intersection of the given regions.

casa::LCIntersection::LCIntersection	(	Bool	takeOver,
		const LCRegion *	region1,
		const LCRegion *	region2 = 0,
		const LCRegion *	region3 = 0,
		const LCRegion *	region4 = 0,
		const LCRegion *	region5 = 0,
		const LCRegion *	region6 = 0,
		const LCRegion *	region7 = 0,
		const LCRegion *	region8 = 0,
		const LCRegion *	region9 = 0,
		const LCRegion *	region10 = 0
	)

Construct from multiple regions.

casa::LCIntersection::LCIntersection	(	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::LCIntersection::LCIntersection

(

const LCIntersection &

Copy constructor (copy semantics).

Member Function Documentation

static String casa::LCIntersection::className

(

)

[static]

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

virtual LCRegion* casa::LCIntersection::cloneRegion

(

)

const [virtual]

Make a copy of the derived object.

Implements casa::LCRegion.

void casa::LCIntersection::defineBox

(

)

[private]

Make the bounding box and determine the offsets.

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

Construct another LCRegion (for e.g.

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

Implements casa::LCRegion.

static LCIntersection* casa::LCIntersection::fromRecord	(	const TableRecord &	,
		const String &	tableName
	)		[static]

Convert correct object from a record.

Reimplemented from casa::LCRegion.

virtual void casa::LCIntersection::multiGetSlice	(	Array< Bool > &	buffer,
		const Slicer &	section
	)		[protected, virtual]

Do the actual getting of the mask.

Implements casa::LCRegionMulti.

LCIntersection& casa::LCIntersection::operator=

(

const LCIntersection &

other

)

Assignment (copy semantics).

virtual Bool casa::LCIntersection::operator==

(

const LCRegion &

other

)

const [virtual]

Comparison.

Reimplemented from casa::LCRegionMulti.

virtual TableRecord casa::LCIntersection::toRecord

(

const String &

tableName

)

const [virtual]

Convert the (derived) object to a record.

Implements casa::LCRegion.

virtual String casa::LCIntersection::type

(

)

const [virtual]

Get the region type.

Returns className()

Implements casa::LCRegion.
