# class RDoc::TopLevel

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

### Attributes

absolute_name[RW]

Absolute name of this file

classes_or_modules[R]

All the classes or modules that were declared in this file. These are assigned to either `#classes_hash` or `#modules_hash` once we know what they really are.

file_stat[RW]

This TopLevel’s `File::Stat` struct

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/top_level.rb, line 43
    def initialize absolute_name, relative_name = absolute_name
      super()
      @name = nil
      @absolute_name = absolute_name
      @relative_name = relative_name
      @file_stat     = File.stat(absolute_name) rescue nil # HACK for testing
      @diagram       = nil
      @parser        = nil

      @classes_or_modules = []
    end

### Public Instance Methods

==(other) click to toggle source

An `RDoc::TopLevel` is equal to another with the same `relative_name`

    # File lib/rdoc/top_level.rb, line 67
    def == other
      self.class === other and @relative_name == other.relative_name
    end
