Detailed Description

Specialized copier for doing spreading of data in dimensionality.

This is a specialized Copier designed to copy from a smaller-dimensional DisjointBoxLayout to a larger-dimensional one by copying all of the data in the transverse direction across the destination boxLayout. It is assumed that this will be used with a different sort of operator (like a spreading 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 spreading.

const Vector< int > &  a_transverseDir,
bool  a_exchange = false 
)

Copier to copy data into the valid and invalid regions of a_dest from a_level.

note that we ignore periodicity for the SpreadingCopier. Do an exchange of the src data before the copyTo which uses this Copier

◆ reverse()

void SpreadingCopier::reverse ( )

reverse the direction of copy for an already-defined SpreadingCopier

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 ReductionCopier rather than a reversed SpreadingCopier

check that this Copier object corresponds to these two BoxLayouts.
