Prerequisite

Etymology

Lattice: "A regular, periodic configuration of points, particles, or objects, throughout an area of a space..." (American Heritage Directory) This definition matches our own: an n-dimensional arrangement of items, on regular orthogonal axes.

Synopsis

This pure abstract base class defines the operations which may be performed on any concrete class derived from it. It has only a few non-pure virtual member functions. The fundamental contribution of this class, therefore, is that it defines the operations derived classes must provide:

The base class LatticeBase contains several functions not dependent on the template parameter.
Tip: Lattices always have a zero origin;

Example

Because Lattice is an abstract base class, an actual instance of this class cannot be constructed. However the interface it defines can be used inside a function. This is always recommended as it allows functions which have Lattices as arguments to work for any derived class.

I will give a few examples here and then refer the reader to the ArrayLattice class (a memory resident Lattice) and the PagedArray class (a disk based Lattice) which contain further examples with concrete classes (rather than an abstract one). All the examples shown below are used in the dLattice.cc demo program.

Example 1:

This example calculates the mean of the Lattice. Because Lattices can be too large to fit into physical memory it is not good enough to simply use getSlice to read all the elements into an Array. Instead the Lattice is accessed in chunks which can fit into memory (the size is determined by the advisedMaxPixels and niceCursorShape functions). The LatticeIterator::cursor() function then returns each of these chunks as an Array and the standard Array based functions are used to calculate the mean on each of these chunks. Functions like this one are the recommended way to access Lattices as the LatticeIterator will correctly setup any required caches.

Complex latMean(const Lattice<Complex>& lat) {
const uInt cursorSize = lat.advisedMaxPixels();
const IPosition cursorShape = lat.niceCursorShape(cursorSize);
const IPosition latticeShape = lat.shape();
Complex currentSum = 0.0f;
size_t nPixels = 0u;
RO_LatticeIterator<Complex> iter(lat,
LatticeStepper(latticeShape, cursorShape));
for (iter.reset(); !iter.atEnd(); iter++){
currentSum += sum(iter.cursor());
nPixels += iter.cursor().nelements();
}
return currentSum/nPixels;
}

unsigned int uInt

Example 2:

Sometimes it will be neccesary to access slices of a Lattice in a nearly random way. Often this can be done using the subSection commands in the LatticeStepper class. But it is also possible to use the getSlice and putSlice functions. The following example does a two-dimensional Real to Complex Fourier transform. This example is restricted to four-dimensional Arrays (unlike the previous example) and does not set up any caches (caching is currently only used with PagedArrays). So only use getSlice and putSlice when things cannot be done using LatticeIterators.

void FFT2DReal2Complex(Lattice<Complex>& result,
const Lattice<Float>& input){
AlwaysAssert(input.ndim() == 4, AipsError);
const IPosition shape = input.shape();
const uInt nx = shape(0);
AlwaysAssert (nx > 1, AipsError);
const uInt ny = shape(1);
AlwaysAssert (ny > 1, AipsError);
const uInt npol = shape(2);
const uInt nchan = shape(3);
const IPosition resultShape = result.shape();
AlwaysAssert(resultShape.nelements() == 4, AipsError);
AlwaysAssert(resultShape(3) == nchan, AipsError);
AlwaysAssert(resultShape(2) == npol, AipsError);
AlwaysAssert(resultShape(1) == ny, AipsError);
AlwaysAssert(resultShape(0) == nx/2 + 1, AipsError);

const IPosition resultSliceShape(4,nx/2+1,ny,1,1);

Note that the LatticeFFT class offers a nice way to do lattice based FFTs.

Example 3:

Occasionally you may want to access a few elements of a Lattice without all the difficulty involved in setting up Iterators or calling getSlice and putSlice. This is demonstrated in the example below. Setting a single element can be done with the putAt function, while getting a single element can be done with the parenthesis operator. Using these functions to access many elements of a Lattice is not recommended as this is the slowest access method.

In this example an ideal point spread function will be inserted into an empty Lattice. As with the previous examples all the action occurs inside a function because Lattice is an interface (abstract) class.

void makePsf(Lattice<Float>& psf) {
const IPosition centrePos = psf.shape()/2;
psf.set(0.0f); // this sets all the elements to zero
// As it uses a LatticeIterator it is efficient
psf.putAt (1, centrePos); // This sets just the centre element to one
AlwaysAssert(near(psf(centrePos), 1.0f, 1E-6), AipsError);
AlwaysAssert(near(psf(centrePos*0), 0.0f, 1E-6), AipsError);
}
Bool near(const GaussianBeam &left, const GaussianBeam &other, const Double relWidthTol, const Quantity &absPaTol)

Motivation

Creating an abstract base class which provides a common interface between memory and disk based arrays has a number of advantages.

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.

◆ dataType()

virtual DataType casacore::Lattice< T >::dataType ( ) const

Get the data type of the lattice.

Implements casacore::LatticeBase.

◆ doGetSlice()

template<class T >
virtual Bool casacore::Lattice< T >::doGetSlice ( Array< T > &  buffer,

The functions (in the derived classes) doing the actual work.

These functions are public, so they can be used internally in the various Lattice classes, which is especially useful for doGetSlice.
However, doGetSlice does not call Slicer::inferShapeFromSource to fill in possible unspecified section values. Therefore one should normally use one of the get(Slice) functions. doGetSlice should be used with care and only when performance is an issue.

template<class T >
Bool casacore::Lattice< T >::get ( COWPtr< Array< T > > &  buffer,
Bool  removeDegenerateAxes = False 
) const

Functions which extract an Array of values from a Lattice.

All the IPosition arguments must have the same number of axes as the underlying Lattice, otherwise, an exception is thrown.
The parameters are:

  • buffer: a COWPtr<Array<T>> or an Array<T>. See example 2 above for an example.
  • start: The starting position (or Bottom Left Corner), within the Lattice, of the data to be extracted.
  • shape: The shape of the data to be extracted. This is not a position within the Lattice but the actual shape the buffer will have after this function is called. This argument added to the "start" argument should be the "Top Right Corner".
  • stride: The increment for each axis. A stride of one will return every data element, a stride of two will return every other element. The IPosition elements may be different for each respective axis. Thus, a stride of IPosition(3,1,2,3) says: fill the buffer with every element whose position has a first index between start(0) and start(0)+shape(0), a second index which is every other element between start(1) and (start(1)+shape(1))*2, and a third index of every third element between start(2) and (start(2)+shape(2))*3.
  • section: Another way of specifying the start, shape and stride
  • removeDegenerateAxes: a Bool which dictates whether to remove "empty" axis created in buffer. (e.g. extracting an n-dimensional from an (n+1)-dimensional will fill 'buffer' with an array that has a degenerate axis (i.e. one axis will have a length = 1.) Setting removeDegenerateAxes = True will return a buffer with a shape that doesn't reflect these superfluous axes.)

The derived implementations of these functions return 'True' if "buffer" is a reference to Lattice data and 'False' if it
is a copy.
