Module: Puppet::Parser::Methods

Extended by:

Util

Defined in:

lib/puppet/parser/methods.rb

Overview

A module for handling finding and invoking methods (functions invokable as a method). A method call on the form:

$a.meth(1,2,3] {|...| ...}

will lookup a function called ‘meth’ and call it with the arguments ($a, 1, 2, 3, <lambda>)
