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

Member Description


LCIntersection()


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



 Construct the intersection of the given regions.

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.

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.

LCIntersection (const LCIntersection& other)



 Copy constructor (copy semantics).

virtual ~LCIntersection()


LCIntersection& operator= (const LCIntersection& other)



 Assignment (copy semantics).

virtual Bool operator== (const LCRegion& other) const



 Comparison

virtual LCRegion* cloneRegion() const



 Make a copy of the derived object.

static String className()



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

virtual String type() const



 Get the region type.  Returns className()  

virtual TableRecord toRecord (const String& tableName) const



 Convert the (derived) object to a record.

static LCIntersection* fromRecord (const TableRecord&, const String& tableName)



 Convert correct object from a record.

virtual LCRegion* doTranslate (const Vector<Float>& translateVector, const IPosition& newLatticeShape) const

 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".

virtual void multiGetSlice (Array<Bool>& buffer, const Slicer& section)



 Do the actual getting of the mask.

void defineBox()

 Make the bounding box and determine the offsets.
