.load(string, options = {}) ⇒ Object

These methods do similar processing to the fallback implemented by MultiJson when using the built-in JSON backend, to ensure consistent behavior whether or not MultiJson can be loaded.

.load_file(filename, options = {}) ⇒ Object

Load the content from a file as JSON.

# File 'lib/puppet/util/json.rb', line 43 def self.load_file(filename, options = {}) json = Puppet::FileSystem.read(filename, :encoding => 'utf-8') load(json, options) end

.load_file_if_valid(filename, options = {}) ⇒ Object

Load the content from a file as JSON if contents are in valid format. This method does not raise error but returns ‘nil` when invalid file is given.
