Method: Oj.register_odd

Defined in:

ext/oj/oj.c

.register_odd(clas, create_object, create_method, *members) ⇒ Object

Registers a class as special. This is useful for working around subclasses of primitive types as is done with ActiveSupport classes. The use of this function should be limited to just classes that can not be handled in the normal way. It is not intended as a hook for changing the output of all classes as it is not optimized for large numbers of classes.

• clas [Class_|Module] Class or Module to be made special

• create_object [Object] object to call the create method on

• create_method [Symbol] method on the clas that will create a new instance of the clas when given all the member values in the order specified.

• members [Symbol_|String] methods used to get the member values from instances of the clas.
