Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Injection and Weaving of parameters

It is possible to inject and weave a set of well known parameters into a call. These extra parameters are not part of the parameters passed from the Puppet logic, and they can not be overridden by parameters given as arguments in the call. They are invisible to the Puppet Language.

The function in the example above is called like this:

test(10, 20)

Examples:

using injected parameters

Puppet::Functions.create_function('test') do
  dispatch :test do
    param 'Scalar', 'a'
    param 'Scalar', 'b'
    scope_param
  end
  def test(a, b, scope)
    a > b ? scope['a'] : scope['b']
  end
end
