find_symbol(symbol, method = nil) public

Look up symbol. If method is non-nil, then we assume the symbol references a module that contains that method.

# File lib/rdoc/context.rb, line 588
  def find_symbol(symbol, method = nil)
    result = nil

    case symbol
    when /^::([A-Z].*)/ then
      result = top_level.find_symbol($1)
    when /::/ then
      modules = symbol.split(/::/)

      unless modules.empty? then
        module_name = modules.shift
        result = find_module_named(module_name)

        if result then
          modules.each do |name|
            result = result.find_module_named name
            break unless result
          end
        end
      end
    end

    unless result then
      # if a method is specified, then we're definitely looking for
      # a module, otherwise it could be any symbol
      if method then
        result = find_module_named symbol

        result = find_local_symbol symbol
        if result.nil? then

            while result && result.name != symbol do
              result = result.parent
