require 'hiera_puppet'
# Provides the base class for the puppet functions hiera, hiera_array, hiera_hash, and hiera_include.
# The actual function definitions will call init_dispatch and override the merge_type and post_lookup methods.
#
# @see hiera_array.rb, hiera_include.rb under lib/puppet/functions for sample usage
