Detailed Description

template<class T>
class BoxLayoutData< T >

Data on a BoxLayout.

A collection of Box-oriented objects. The arrangement of Boxes is given by the underlying BoxLayout object. BoxLayoutData attempt to prevent users from maniupulating the template class T to become out of synch with the boxes in the BoxLayout. Caveat emptor.

All access to the data in a BoxLayoutData is forced to be data-parallel, by use of the DataIterator.

class T must provide the following methods: \begin{itemize} \item {\tt T()} \item {\tt T(const Box& box, int comps)} \item {\tt define(const Box& box, int comps)} \item {\tt void copy(const Box& R, const Interval& Cd, const T& source, const Interval Cs)} Cs and Cd must have same length, but can be displaced

\item {\tt static int preAllocatable()} returns 0 if the size(...) function is strictly a function of Box and Interval, and does not depend on the current state of the T object. return 1 if size(..) is symmetric, in that sender and receiver T object can size their message buffers, but a static object cannot. returns 2 if the object is truly dynamic. the message size is subject to unique object data. \item {\tt int size(const Box& R, const Interval& comps)} \item {\tt void linearOut(void* buf, const Box& R, const Interval& comps)} \item {\tt void linearIn(void* buf, const Box& R, const Interval& comps)} \end{itemize}

In sequential codes, many of these functions will not be called, but in the general parallel case, they all will be.
