Inheritance diagram for casa::MomentCalcBase< T >:
Part of API
This class, its concrete derived classes, and the classes LineCollapser, ImageMoments and LatticeApply are connected as follows. LatticeApply offers functions so that the application programmer does not need to worry about how to optimally iterate through a Lattice; it deals with tiling and to a lesser extent memory. LatticeApply functions are used by offering a class object to them that has a member function with a name and signature specified by an abstract base class that LatticeApply uses and the offered class inherits from. Specifically, in this case, MomentCalcBase inherits from LineCollapser and LatticeApply uses objects and methods of this class (but does not inherit from it). This defines the functions collapse and multiProcess which operate on a vector extracted from a Lattice. The former returns one number, the latter a vector of numbers from that profile. MomentCalcBase is a base class for for moment calculation and the multiProcess functions are used to compute moments (e.g., mean, sum, sum squared, intensity weighted velocity etc).
It is actually the concrete classes derived from MomentCalcBase (call them, as a group, the MomentCalculator classes) that implement the multiProcess functions. These derived classes allow different algorithms to be written with which moments of the vector can be computed.
Now, so far, we have a LatticeApply function which iterates through Lattices, extracts vectors, and offers them up to functions implemented in the derived MomentCalculator classes to compute the moments. As well as that, we need some class to actually construct the MomentCalculator classes and to feed them to LatticeApply. This is the role of the ImageMoments class. It is a high level class which takes control information from users specifying which moments they would like to calculate and how. It also provides the ancilliary masking lattice to the MomentCalculator constructors. The actual computational work is done by the MomentCalculator classes. So ImageMoments, MomentCalcBase and its derived MomentCalculator classes are really one unit; none of them are useful without the others. The separation of functionality is caused by having the LatticeApply class that knows all about optimally iterating through Lattices.
The coupling between these classes is done partly by the "friendship". ImageMoments grants friendship to MomentCalcBase so that the latter has access to the private data and private functions of ImageMoments. MomentCalcBase then operates as an interface between its derived MomentCalculator classes and ImageMoments. It retrieves private data from ImageMoments, and also activates private functions in ImageMoments, on behalf of the MomentCalculator classes. The rest of the coupling is done via the constructors of the derived MomentCalculator classes.
Finally, MomentCalcBase also has a number of protected functions that are common to its derived classes (e.g. plotting, fitting, accumulating sums etc). It also has protected data that is common to all the MomentCalculator classes. This protected data is accessed directly by name rather than with interface functions as there is too much of it. Of course, since MomentCalcBase is an abstract base class, it is up to the MomentCalculator classes to give the MomentCalcBase protected data objects values.
For discussion about different moments and algorithms to compute them see the discussion in ImageMoments and also in the derived classes documentation.
Since MomentCalcBase is an abstract class, we defer code examples to the derived classes.
We were desirous of writing functions to optimally iterate through Lattices so that the application programmer did not have to know anything about tiling or memory if possible. These are the LatticeApply functions. To incorporate ImageMoments into this scheme required some of it to be shifted into MomentCalcBase and its derived classes.
Tip: Note that there are is assignment operator or copy constructor. Do not use the ones the system would generate either.
