Member Function Documentation
| virtual void paludis::MetadataKeyHolder::add_metadata_key | ( | const std::tr1::shared_ptr< const MetadataKey > & | ) | const [protected, virtual] |
Add a new MetadataKey, which must not use the same raw name as any previous MetadataKey added to this ID.
| virtual void paludis::MetadataKeyHolder::clear_metadata_keys | ( | ) | const [protected, virtual] |
Clear all MetadataKey instances added using add_metadata_key.
Reimplemented in paludis::ConditionalDepSpec.
| virtual void paludis::MetadataKeyHolder::need_keys_added | ( | ) | const [protected, pure virtual] |
This method will be called before any of the metadata key iteration methods does its work. It can be used by subclasses to implement as-needed loading of keys.
Implemented in paludis::AnyDepSpec, paludis::AllDepSpec, paludis::ConditionalDepSpec, paludis::PackageDepSpec, paludis::PlainTextDepSpec, paludis::NamedSetDepSpec, paludis::LicenseDepSpec, paludis::FetchableURIDepSpec, paludis::SimpleURIDepSpec, paludis::BlockDepSpec, paludis::LabelsDepSpec< SpecTree_ >, paludis::NoConfigEnvironment, paludis::TestEnvironment, paludis::FakePackageID, and paludis::FakeRepositoryBase.
