require 'hiera/puppet_function'
# Returns all matches throughout the hierarchy --- not just the first match --- as a flattened array of unique values.
# If any of the matched values are arrays, they're flattened and included in the results.
#
# The function can be called in one of three ways:
# 1. Using 1 to 3 arguments where the arguments are:
# 'key' [String] Required
# The key to lookup.
# 'default` [Any] Optional
# A value to return when there's no match for `key`. Optional
# `override` [Any] Optional
# An argument in the third position, providing a data source
# to consult for matching values, even if it would not ordinarily be
# part of the matched hierarchy. If Hiera doesn't find a matching key
# in the named override data source, it will continue to search through the
# rest of the hierarchy.
#
# 2. Using a 'key' and an optional 'override' parameter like in #1 but with a block to
# provide the default value. The block is called with one parameter (the key) and
# should return the value.
#
# 3. Like #1 but with all arguments passed in an array.
# If any matched value is a hash, puppet will raise a type mismatch error.
#
# More thorough examples of `hiera` are available at:
# <http://docs.puppetlabs.com/hiera/1/puppet.html#hiera-lookup-functions>
