class Mechanize::File

This is the base class for the Pluggable Parsers. If Mechanize cannot find an appropriate class to use for the content type, this class will be used. For example, if you download an image/jpeg, Mechanize will not know how to parse it, so this class will be instantiated.

This is a good class to use as the base class for building your own pluggable parsers.

Example

require 'mechanize'

agent = Mechanize.new
agent.get('http://example.com/foo.jpg').class  #=> Mechanize::File

Attributes

body[RW]

The HTTP response body, the raw file contents

content[RW]

The HTTP response body, the raw file contents

filename[RW]

The filename for this file based on the content-disposition of the response or the basename of the URL
