Member Function Documentation

◆ accumulate_changes_to_make_met()

Tribool paludis::UserKeyRequirement::accumulate_changes_to_make_met	(	const Environment * const	,
		const ChangedChoices * const	maybe_changes_to_owner,
		const std::shared_ptr< const PackageID > &	,
		const std::shared_ptr< const PackageID > &	spec_id,
		ChangedChoices &	) const

overridevirtual

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

Implements paludis::AdditionalPackageDepSpecRequirement.

◆ as_human_string()

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

overridevirtual

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

Implements paludis::AdditionalPackageDepSpecRequirement.

References PALUDIS_ATTRIBUTE.

◆ as_raw_string()

const std::string paludis::UserKeyRequirement::as_raw_string ( ) const

overridevirtual

Return a raw string representation of ourself.

Implements paludis::AdditionalPackageDepSpecRequirement.

References PALUDIS_ATTRIBUTE.

◆ requirement_met()

const std::pair< bool, std::string > paludis::UserKeyRequirement::requirement_met	(	const Environment * const	,
		const ChangedChoices *	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

overridevirtual

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

Implements paludis::AdditionalPackageDepSpecRequirement.
