Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

BytecodeScanner scans Ruby bytecode instructions for constant references.

This class traverses the ISeq#to_a representation to find:

  • :getconstant instructions - simple constant references

  • :opt_getconstant_path instructions - optimized qualified constant paths

API:

  • private
