virtual tr1::shared_ptr<RepositoryNameSequence> paludis::QueryDelegate::repositories

(

const Environment &

)

const [virtual]

Fetch the names of repositories potentially containing matches. All returned repositories must exist.

Default behaviour: return all repositories.

virtual tr1::shared_ptr<CategoryNamePartSet> paludis::QueryDelegate::categories	(	const Environment &	,
		tr1::shared_ptr< const RepositoryNameSequence >
	)			const [virtual]

Fetch the names of categories potentially containing matches.

Default behaviour: return all categories in the provided repository collection.

virtual tr1::shared_ptr<QualifiedPackageNameSet> paludis::QueryDelegate::packages	(	const Environment &	,
		tr1::shared_ptr< const RepositoryNameSequence >	,
		tr1::shared_ptr< const CategoryNamePartSet >
	)			const [virtual]

Fetch the names of packages potentially containing matches.

Default behaviour: return all packages in the provided repository in the provided categories.

Note that some entries in the categories collection (but not in the repositories collection) may not exist.

virtual tr1::shared_ptr<PackageIDSequence> paludis::QueryDelegate::ids	(	const Environment &	,
		tr1::shared_ptr< const RepositoryNameSequence >	,
		tr1::shared_ptr< const QualifiedPackageNameSet >
	)			const [virtual]

Fetch the IDs of matching packages.

Default behaviour: return all IDs in the provided packages.

Note that some entries in the qualified package name collection (but not in the repositories collection) may not exist.

Examples:

virtual std::string paludis::QueryDelegate::as_human_readable_string
