		const ChangedChoices *const	maybe_changes_to_owner,

pure virtual

If possible, indicate which choices to change to make our requirement met for a particular ID.

Verifies that the ID has the appropriate choice, and that that choice isn't locked.

Returns true for changes made, false for not possible, indeterminate for nothing needs changing.

Parameters

spec_id The PackageID the spec comes from. May be null. Used for [use=] style dependencies.

Since: 0.51; 0.55 returns Tribool; 0.58 takes spec_id

Implemented in paludis::ExcludeRequirement, and paludis::UserKeyRequirement.

virtual const std::string paludis::AdditionalPackageDepSpecRequirement::as_human_string ( const std::shared_ptr< const PackageID > & spec_id ) const

pure virtual

Return a human readable string representation of ourself.

Parameters

spec_id The PackageID the spec comes from. May be null. Used for [use=] style dependencies.

Since: 0.58 takes spec_id

Implemented in paludis::ExcludeRequirement, and paludis::UserKeyRequirement.

virtual const std::string paludis::AdditionalPackageDepSpecRequirement::as_raw_string ( ) const

pure virtual

Return a raw string representation of ourself.

Implemented in paludis::ExcludeRequirement, and paludis::UserKeyRequirement.

virtual const std::pair<bool, std::string> paludis::AdditionalPackageDepSpecRequirement::requirement_met	(	const Environment *	const,
		const ChangedChoices *const	maybe_changes_to_owner,
		const std::shared_ptr< const PackageID > &	target_id,
		const std::shared_ptr< const PackageID > &	spec_id,
		const ChangedChoices *const	maybe_changes_to_target
	)		const

pure virtual

Is our requirement met for a given PackageID?

The string in the return type might be a description of why the requirement was not met. Sometimes better messages can be given than simply the return value of as_human_string() when the ID to be matched is known. If the bool is true, the string is meaningless.

Parameters

spec_id The PackageID the spec comes from. May be null. Used for [use=] style dependencies.

Since: 0.44 returns pair<bool, std::string>; 0.51 takes optional ChangedChoices arguments; 0.58 takes id by shared_ptr; 0.58 takes spec_id

Implemented in paludis::ExcludeRequirement, and paludis::UserKeyRequirement.
