Module: Tapioca::Runtime::Trackers::ConstantDefinition

Extended by:
T::Sig, Reflection, Tracker
Defined in:
lib/tapioca/runtime/trackers/constant_definition.rb

Overview

Registers a TracePoint immediately upon load to track points at which classes and modules are opened for definition. This is used to track correspondence between classes/modules and files, as this information isn’t available in the ruby runtime without extra accounting.

.files_for(klass) ⇒ Object

Returns the files in which this class or module was opened. Doesn’t know about situations where the class was opened prior to requireing, or where metaprogramming was used via eval, etc. : (Module klass) -> Set
