| void ParaMEDMEM.OverlapElementLocator::exchangeMeshes | ( | OverlapInterpolationMatrix & | matrix | ) |
The aim of this method is to perform the communication to get data corresponding to '_to_do_list' attribute. The principle is the following : if proc n1 and n2 need to perform a cross sending with n1<n2, then n1 will send first and receive then.

This methods sends local source if 'sourceOrTarget'==True to proc 'procId'. This methods sends local target if 'sourceOrTarget'==False to proc 'procId'.
This method prepares the matrix too, for matrix assembling and future matrix-vector computation.
