Detailed Description
template<class TLayout>
class ug::ComPol_SynchronizeDistInfos< TLayout >
Communicates the distribution infos through existing interfaces.
Distribution infos are packed into the send buffer for each node and are either merged with existing entries or existing entries are simply overwritten. The merge/overwrite behavior can be chosen through the member method enable_merge.

returns the size of the buffer in bytes, that will be required for interface-communication.
Determines the size of the buffer on which the extract and receive methods for the given interface will operate. If the buffer-size can't be calculated on both sides (sender and receiver) this method should return -1. This will lead to an additional communication step in which buffer-sizes will be exchanged. If the buffer-size can be calculated on both sides, it makes sense to do so, since this leads to less communication and overall improved performance. The buffer-size has to exactly match the size of required memory. Make sure that you completely fill the buffer during collect(...) and that you read all data during extract(...). The default implementation returns -1.
Reimplemented from pcl::ICommunicationPolicy< TLayout >.
