Detailed Description

Specialized copier for doing reductions in dimensionality.

This is a specialized Copier designed to copy from a multi-dimensional DisjointBoxLayout to a smaller-dimensional one by copying all of the data in the transverse direction to the destination boxLayout. It is assumed that this will be used with a different sort of operator (like a summation operator, for example), since a straight copy operation wouldn't make much sense. Anyway, this just defines the intersection regions; what you do with them is your problem.

Note also that both the Spreading and Reduction Copiers ignore periodicity, since it can lead to unintended side-effects and multiple-counting of data. The way to handle periodicity is to do an exchange on the source data before calling the copyTo which does the reduction.

void ReductionCopier::reverse ( )

reverse the direction of copy for an already-defined ReductionCopier

This function simply replaces the from data with the to-data for the already-defined copy operation. For now, this function heads right into a MayDay::Error, since what you probably want is to use a SpreadingCopier rather than a reversed ReductionCopier

bool ReductionCopier::check ( const DisjointBoxLayout from,
const BoxLayout to 
) const

check that this Copier object corresponds to these two BoxLayouts.
