Abstract base class to define a single region.
Public interface
The LCRegion class is the abstract base class for various types of LCRegion's (e.g. LCRegionEllipsoid, LCRegionBox). It contains the minimal bounding box of the region and, if needed, a mask with the same shape as the bounding box. A mask element is true if the element is inside the box.
Each LCRegion object must be able to convert itself to and from a Record. In that way they can be made persistent (in for example a Table).
The LCRegion can be used in several Lattices and Images classes and functions to limit the area to operate on.
The Slicer class is too limited as a region, because it can only describe a rectangular region. Specialized classes are needed to describe arbitrary regions. They need a base class to combine them.

casacore::LCRegionSingle::LCRegionSingle | ( | ) |
casacore::LCRegionSingle::LCRegionSingle | ( | const IPosition & | latticeShape | ) |
Construct with the lattice shape only.
casacore::LCRegionSingle::LCRegionSingle | ( | const LCRegionSingle & | other | ) |
Copy constructor (copy semantics).
|
virtual |
Replace every element, x, of the Lattice with the result of f(x).
You must pass in the address of the function – so the function must be declared and defined in the scope of your program. All versions of apply require a function that accepts a single argument of type T (the Lattice template type) and return a result of the same type. The first apply expects a function with an argument passed by value; the second expects the argument to be passed by const reference; the third requires an instance of the class Functional<T,T>
. The first form ought to run faster for the built-in types, which may be an issue for large Lattices stored in memory, where disk access is not an issue.
