Class: RubyProf::GraphHtmlPrinter

Inherits:
AbstractPrinter show all
Includes:
ERB::Util
Defined in:
lib/ruby-prof/printers/graph_html_printer.rb

Overview

Generates graph profile reports as html. To use the graph html printer:

result = RubyProf.profile do
  [code to profile]
end

printer = RubyProf::GraphHtmlPrinter.new(result)
printer.print(STDOUT, :min_percent=>0)

The Graph printer takes the following options in its print methods:

:filename    - specify a file to use that contains the ERB
               template to use, instead of the built-in self.template

:template    - specify an ERB template to use, instead of the
               built-in self.template

Instance Method Details

Creates a link to a method. Note that we do not create links to methods which are under the min_perecent specified by the user, since they will not be printed out.
