interpreter/attribute_patterns.go:210–229

MaybeAttribute implementation of the AttributeFactory interface which ensure that the set of 'maybe' NamespacedAttribute values are produced using the partialAttributeFactory rather than the base AttributeFactory implementation.

(id int64, name string)

// 'maybe' NamespacedAttribute values are produced using the partialAttributeFactory rather than
// the base AttributeFactory implementation.
func (fac *partialAttributeFactory) MaybeAttribute(id int64, name string) Attribute {
	var names []string
	// When there's a single name with a dot prefix, it indicates that the 'maybe' attribute is a
	// globally namespaced identifier.
	if strings.HasPrefix(name, ".") {
		names = append(names, name)
	} else {
		// In all other cases, the candidate names should be inferred.
		names = fac.container.ResolveCandidateNames(name)
	}
	return &maybeAttribute{
		id: id,

			fac.AbsoluteAttribute(id, names...),

// matchesUnknownPatterns returns true if the variable names and qualifiers for a given
