Detailed Description

template<typename Heirarchy_, typename Item_>
class paludis::DepSpecFlattener< Heirarchy_, Item_ >

Extract the enabled components of a dep heirarchy for a particular package. Sets, via NamedSetDepSpec, are automatically expanded.

This template can be instantiated as:

• DepSpecFlattener<ProvideSpecTree, PackageDepSpec>
• DepSpecFlattener<PlainTextSpecTree, PlainTextDepSpec>
• DepSpecFlattener<SetSpecTree, PackageDepSpec>
• DepSpecFlattener<SimpleURISpecTree, SimpleURIDepSpec>

It is not suitable for heirarchies that can contain AnyDepSpec. Any labels are discarded.

Since:

0.26

Examples:

example_dep_spec_flattener.cc, and example_dep_tag.cc.
