class RDoc::TopLevel

A TopLevel context is a representation of the contents of a single file

Attributes

absolute_name[RW]

parser[R]

The parser class that processed this file

relative_name[RW]

Relative name of this file

Public Class Methods

new(absolute_name, relative_name = absolute_name) click to toggle source

Creates a new TopLevel for the file at absolute_name. If documentation is being generated outside the source dir relative_name is relative to the source directory.

Calls superclass method RDoc::Context::new
# File lib/rdoc/code_object/top_level.rb, line 43
def initialize absolute_name, relative_name = absolute_name
  super()
  @name = nil
  @absolute_name = absolute_name
  @relative_name = relative_name
