Instance Method Details

#add_attributes(keys) ⇒ void

This method returns an undefined value.

Adds attribute accessors, predicates, and mutators for the named keys. Since these methods will also be instantly available on all instances of the parent class, each of these methods will also conservatively PuppetForge::LazyAccessors#fetch any missing data.
