Class: SimpleCov::SourceFile::MethodBuilder

Relationships & Source Files
Inherits: Object
Defined in: lib/simplecov/source_file/method_builder.rb

Overview

Builds the Method objects for a source file from the raw method-coverage data. Applies the ignore_methods :eval_generated filter and marks methods inside # simplecov:disable / # :nocov: chunks as skipped.

    #eval_generated_to_ignore?(info)  ⇒ Boolean  (private)
  



  

    
See BranchBuilder#eval_generated_condition_to_ignore? for the
rationale. Coverage reports an eval'd def at the eval caller's
line and name, so a method whose (name, start_line) is absent
from the real-source def set is eval-generated. Only consulted
when the user has opted in via
SimpleCov.ignore_methods :eval_generated. See #1046.
