Class Body
implementing the concept of parallel_scan body must define:
Body::Body( Body&, split );
b
so that this
and b
can accumulate separatelyBody::~Body();
void Body::operator()( const Range& r, pre_scan_tag );
r
void Body::operator()( const Range& r, final_scan_tag );
r
void Body::reverse_join( Body& a );
a
into this
, where a
was created earlier from b
by b's splitting constructor
