--- !ruby/object:RI::MethodDescription aliases: [] block_params: comment: - !ruby/struct:SM::Flow::P body: "Invoked when a reference is made to an undefined constant in <em>mod</em>. It is passed a symbol for the undefined constant, and returns a value to be used for that constant. The following code is a (very bad) example: if reference is made to an undefined constant, it attempts to load a file whose name is the lowercase version of the constant (thus class <tt>Fred</tt> is assumed to be in file <tt>fred.rb</tt>). If found, it returns the value of the loaded class. It therefore implements a perverse kind of autoload facility." - !ruby/struct:SM::Flow::VERB body: " def Object.const_missing(name)\n @looked_for ||= {}\n str_name = name.to_s\n raise &quot;Class not found: #{name}&quot; if @looked_for[str_name]\n @looked_for[str_name] = 1\n file = str_name.downcase\n require file\n klass = const_get(name)\n return klass if klass\n raise &quot;Class not found: #{name}&quot;\n end\n" full_name: Module#const_missing is_singleton: false name: const_missing params: | mod.const_missing(sym) => obj visibility: public
