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.

Defined Under Namespace

Classes: ConstantLocation
