Module: SimpleCov::StaticCoverageExtractor::MethodCollector

Relationships & Source Files
Extension / Inclusion / Inheritance Descendants
Included In: `Visitor`
Defined in:	lib/simplecov/static_coverage_extractor/method_collector.rb

Overview

Visitor mixin that collects method tuples and tracks the lexical class / module nesting that names them, in the shape Ruby's Coverage reports methods. Mixed into Visitor, it shares that visitor's @methods / @class_stack state and keeps the method-collection concern separate from branch extraction.

Instance Method Summary

#visit_class_node(node)

Track class/module nesting so method tuples carry the lexical class name.
#visit_def_node(node)
def name(...) and def self.name(...) both produce DefNode.
#visit_module_node(node)
#constant_name(node) private

Render a constant path (e.g., Foo::Bar) as its source-form string.
#with_class(name) private

simplecov:enable.

Instance Method Details

#constant_name(node) (private)

Render a constant path (e.g., Foo::Bar) as its source-form string. Defensive nil / to_s fallbacks: ClassNode and ModuleNode always carry a constant_path in practice. simplecov:disable

def constant_name(node)
  return "<anonymous>" if node.nil?
  return node.slice if node.respond_to?(:slice)

  node.to_s
end

#visit_class_node(node)

Track class/module nesting so method tuples carry the lexical class name. Module + Class are both treated as namespaces here since Coverage reports both as the constant.

def visit_class_node(node)
  with_class(constant_name(node.constant_path)) { super }
end

#visit_def_node(node)

def name(...) and def self.name(...) both produce DefNode. The class context is the surrounding lexical class/module (or Object at the top level, matching Coverage's convention).
