## Detailed Description

Capabilities iterator.

A forward iterator over a libsolv id array. Automatically skips internal dep-marker ids, setting the tagged flag when it does so to indicate that subsequent capabilities carry a special property (e.g. pre-requires within a solvable's requires list).

## Member Function Documentation

## ◆ tagged()

bool zyppng::sat::Capabilities::const_iterator::tagged | ( |  | ) | const
| inline

Return `true` if the Capability is `tagged`.

The meaning of `tagged` depends on the kind of dependency you are processing. It is a hint that the iterator skipped some internal marker, indicating that subsequent capabilities have a special property. Within a Solvable's requirements e.g. the pre-requirements are tagged.

Capabilities req( solvable.dep_requires() );
for ( auto it = req.begin(); it != req.end(); ++it )
{
if ( it.tagged() )
cout << *it << " (is prereq)" << endl;
else
cout << *it << endl;
}
