Class
Foam::IPstreamImpl
Description
Abstract base class for IPstream operations that depend on the parallel
library used. Foam::IPstreamImpl::New will lookup the entry
"PstreamImplementation" in the global controlDict file (i.e. the one
found by Foam::dotFoam) and tries to first load a library named
lib\<PstreamImplementation\>Pstream.so, and then instantiate the class
\<PstreamImplementation\>IPstreamImpl.
