Detailed Description

Bridging class to allow C++ expressions involving lattices

Intended use:

Public interface

Review Status

Date Reviewed:: yyyy/mm/dd

Prerequisite

Etymology

The name is derived from the fact that this class provides an expression interface to the user which s/he may use to write C++ expressions involving Lattices. This class actually constructs the nodes of the expression tree, hence its name. It is used by the envelope class LatticeExpr and provides a bridge to the letter classes derived from LELInterface.

Synopsis

This class is part of the interface which allows the C++ programmer to enter mathematical expressions involving Lattices. It is is part of a Letter/envelope scheme. It's actually a bridge between the envelope class (LatticeExpr) and the letter classes (derived from LELInterface) and it exists largely to handle type conversions. In a single type environment, the envelope class could have directly called the letter classes.

The envelope and bridge provide the interface which the programmer sees. The letter classes do the real work and are hidden from the programmer.

All the expression manipulation functionality that the user has access to is viewable in this class; it is here that the operators, functions and constructors are defined. These allow the programmer to write mathematical expressions which involve Lattices. The letter classes take care of the optimal traversal of the Lattice and the memory mangement thereof. Thus the Lattices are iterated through and the expressions evaluated for each chunk (usually a tile shape) of the iteration.

A description of the implementation details of these classes can be found in Note 216

The available functionality is defined by the global friend functions and operators, plus the public constructors. The other public members functions are generally not of interest to the user of this class.

Generally, if one writes an expression such as a.copyData(sin(b)), the expression is automatically converted first to a LatticeExprNode and then to a LatticeExpr (which is a Lattice) before evaluation occurs. However, it may occur that you wish to build an expression from subexpressions. To do this, you must explcitly create objects of class LatticeExprNode. You cannot manipulate subexpressions of type LatticeExpr<T>. See below for an example.

Example

ArrayLattice<Float>   f1(IPosition (2,nx,ny));
ArrayLattice<Float>   f2(IPosition (2,nx,ny));
f2.set(2.0);
f1.copyData(2*f2+f2);

In this example, the values of the pixels in Lattice f1 are set to the values resulting from the expression "2*f2 + f2" I.e. the expression is evaluated for each pixel in the Lattices

Note that :

1) the Lattice::copyData function is expecting a Lattice argument.
2) LatticeExpr inherits from Lattice and therefore a LatticeExpr object is a valid argument object type 3) The expression in the copyData call is automatically converted to a LatticeExprNode by the constructors and operators in LatticeExprNode 4) The LatticeExprNode object so created is automatically converted to a LatticeExpr by casting functions in LatticeExprNode.

Example

ArrayLattice<Float>   f1(IPosition (2,nx,ny));
ArrayLattice<Float>   f2(IPosition (2,nx,ny));
ArrayLattice<Double>  d(IPosition (2,nx,ny));
ArrayLattice<Complex> c(IPosition (2,nx,ny));
ArrayLattice<Bool>    b(IPosition (2,nx,ny));
 
f2.set(1.0); d.set(2.0); c.set(Complex(2.0,3.0)); b.set(True);
f1.copyData((3.5*f2) + (cos(d)) - (10/min(d,f2)*(-abs(c))*ntrue(b)) - (C::pi));

In this rather silly example, we fill Lattice "f1" with the result of the expression. The expression shows the use of constants, unary operations, binary operations, 1D and 2D functions. It also shows how mixed types can be handled. The output Lattice is a Float, whereas mixed into the expression are subexpressions involving Float, Double, Complex and Bool Lattices.

Example

ArrayLattice<Float>   f1(IPosition (2,nx,ny));
ArrayLattice<Float>   f2(IPosition (2,nx,ny));
f2.set(2.0);
LatticeExprNode exp1(sin(f2));
LatticeExprNode exp2(pow(f2,2.0));
f1.copyData(exp1+exp2);

In this example, the expression is "sin(f2) + pow(f2,2.0)", but we have put it together from two subexpressions contained in LatticeExprNode objects exp1 and exp2. Again the LatticeExprNode object formed from summing exp1 and exp2 is automatically converted to a LatticeExpr for consumption by copyData

Motivation

The Lattice expression classes enable the C++ programmer much simpler handling of mathematical expressions involving lattices. In addition, these classes provide the infrastructure on top of which we can build an image calculator for Glish users
