## Detailed Description

Build string to identify/retrieve a specific Solvable.

"[<namespace>:]<name>-<version>-<release>.<arch>@<repoalias>"

Any namespace that prepends the InstanceIds must be passed to the ctor. Conversion to/from instanceId can be done via function call `operator()`.

InstanceId instanceId( "SUSE:" ); // using a namespace
ResPool pool( ResPool::instance() );
for_( it, pool.begin(), pool.end() )
{
std::cout << instanceId(*it) << endl;
}
for_
#define for_(IT, BEG, END)
Convenient for-loops using iterator.
