-
.class_for_json_class(json_class) ⇒ Object
Map
JSON_CLAZ
to a Class object. -
.from_json(source, opts = {}) ⇒ Object
Just call the JSON gem’s parse method with a modified :max_nesting field.
- .map_hash_to_rb_obj(json_hash) ⇒ Object
-
.map_to_rb_obj(json_obj) ⇒ Object
Look at an object that’s a basic type (from json parse) and convert it to an instance of Chef classes if desired.
-
.parse(source, opts = {}) ⇒ Object
API to use to avoid create_addtions.
- .to_json(obj, opts = nil) ⇒ Object

Class Method Details
.class_for_json_class(json_class) ⇒ Object
Map JSON_CLAZ
to a Class object. We use a case
instead of a Hash assigned to a constant because otherwise this file could not be loaded until all the constants were defined, which means you’d have to load the world to get json.
.from_json(source, opts = {}) ⇒ Object
Just call the JSON gem’s parse method with a modified :max_nesting field

# File 'lib/megam/core/json_compat.rb', line 71 def from_json(source, opts = {}) obj = parse(source, opts) # JSON gem requires top level object to be a Hash or Array (otherwise # you get the "must contain two octets" error). Yajl doesn't impose the # same limitation. For compatibility, we re-impose this condition. unless obj.kind_of?(Hash) || obj.kind_of?(Array) raise JSON::ParseError, "Top level JSON object must be a Hash or Array. (actual: #{obj.class})" end # The old default in the json gem (which we are mimicing because we # sadly rely on this misfeature) is to "create additions" i.e., convert # JSON objects into ruby objects. Explicit :create_additions => false # is required to turn it off. if opts[:create_additions].nil? || opts[:create_additions] map_to_rb_obj(obj) else obj end end |
