Detailed Description

Calling Environment::operator[] with a Selection parameter is the usual way of querying for PackageID instances with given properties.

Function Documentation

Generator paludis::operator&	(	const Generator &	,
		const Generator &
	)

Two Generator instances can be and-ed together, to obtain only PackageID instances that satisfy the constraints of Generator instances.

Generator paludis::operator+	(	const Generator &	,
		const Generator &
	)

Two Generator instances can be added, to obtain PackageID instances that satisfy the constraints of either Generator instance.

std::ostream& paludis::operator<<	(	std::ostream &	,
		const Generator &
	)

A FilteredGenerator can be represented as a string. Generally this is used only for stringifying a Selection.

std::ostream& paludis::operator<<	(	std::ostream &	,
		const Filter &
	)

A Filter can be represented as a string, can be written to a stream.

std::ostream& paludis::operator<<	(	std::ostream &	,
		const Selection &
	)

A Selection can be represented as a string, can be written to a stream.

std::ostream& paludis::operator<<	(	std::ostream &	,
		const FilteredGenerator &
	)

A FilteredGenerator can be represented as a string. Generally this is used only for stringifying a Selection.

FilteredGenerator paludis::operator|	(	const FilteredGenerator &	,
		const Filter &
	)

A FilteredGenerator can be combined with another Filter to further restrict desired properties.
