Detailed Description

Make the union of 2 or more regions.

Intended use:

Public interface

Prerequisite

• LCRegion

Synopsis

The LCUnion class is a specialization of class LCRegion . It makes it possible to extend a LCRegion along straight lines to other dimensions. E.g. a circle in the xy-plane can be extended to a cylinder in the xyz-space. includes the union border. It can only be used for a lattice of any dimensionality as long as the dimensionality of the (hyper-)union matches the dimensionality of the lattice.

The center of the union must be inside the lattice

Example

To Do

• Expand along (slanted) cone lines

Constructor & Destructor Documentation

casa::LCUnion::LCUnion

(

)

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

Construct the union of the given regions.

casa::LCUnion::LCUnion	(	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.

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

casa::LCUnion::LCUnion	(	Bool	takeOver,
		const PtrBlock< const LCRegion * > &	regions
	)

casa::LCUnion::LCUnion

Member Function Documentation

static String casa::LCUnion::className

(

)

[static]

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

virtual LCRegion* casa::LCUnion::cloneRegion

(

)

const [virtual]

Make a copy of the derived object.

Implements casa::LCRegion.

void casa::LCUnion::defineBox

(

)

[private]

Make the bounding box and determine the offsets.

virtual LCRegion* casa::LCUnion::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 LCUnion* casa::LCUnion::fromRecord	(	const TableRecord &	,
		const String &	tableName
	)		[static]

Convert correct object from a record.

Reimplemented from casa::LCRegion.

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

Do the actual getting of the mask.

Implements casa::LCRegionMulti.

LCUnion& casa::LCUnion::operator=

(

const LCUnion &

other

)

Assignment (copy semantics).

virtual Bool casa::LCUnion::operator==

(

const LCRegion &

other

)

const [virtual]

Comparison.

Reimplemented from casa::LCRegionMulti.

virtual TableRecord casa::LCUnion::toRecord

(

const String &

tableName

)

const [virtual]

Convert the (derived) object to a record.

Implements casa::LCRegion.

virtual String casa::LCUnion::type

(

)

const [virtual]

Get the region type.

Returns className()

Implements casa::LCRegion.
