Member Function Documentation

virtual void paludis::MetadataKeyHolder::add_metadata_key ( const std::shared_ptr< const MetadataKey > &  ) const

protectedvirtual

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

protectedvirtual

Clear all MetadataKey instances added using add_metadata_key.

virtual void paludis::MetadataKeyHolder::need_keys_added ( ) const

protectedpure 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::FakePackageID, paludis::ContentsEntry, paludis::AboutMetadata, paludis::FakeRepositoryBase, and paludis::TestEnvironment.
