Synopsis

This is an abstract base class for classes to monitor the progress of an operation on a Lattice. The default implementation offered by this class does nothing. However, a derived class could show the progress using for example a ProgressMeter. A derived class should override the virtual functions from this class.

The user of the LatticeCleanProgress object should first call function init with the total number of steps that are to be done. Thereafter, after each step has been executed, function nstepsDone should be called after each step. Finally, function done should be called.

Example

Motivation

Since operations on Lattices can take a while, it can be useful to show the progress. However, making module Lattices dependent on the class ProgressMeter sounded bad. This abstract class serves as a bridge between the Lattice module and the ProgressMeter class (or any other class showing the progress).

this will redraw the plot with a new scale; if plotMatrices = False, just draw the boxes, else, replot all past data.

initizalize the arrays and such

void casacore::LatticeCleanProgress::plotOne ( const Int  iteration, const Vector< Float > &  resid, const Vector< Float > &  flux  )

Note: you MUST call basicSetUp before calling this.

void casacore::LatticeCleanProgress::resizeDataStorage ( )

private

As the iterations trickle in, we will from time to time need to make the Matrices larger.
