Dynamic Method Handling

This class handles dynamic methods through the method_missing method in the class Chef::Resource

Instance Attribute Details

#is_guard_interpreter ⇒ Object

The ResourceGuardInterpreter wraps a resource’s guards in another resource. That inner resource needs to behave differently during (for example) why_run mode, so we flag it here. For why_run mode we still want to execute the guard resource even if we are not executing the wrapping resource. Only execute resources (and subclasses) can be guard interpreters.
