dump(obj, anIO = nil, limit = nil) Instance Public methods Dumps obj as a JSON string, i.e. calls generate on the object and returns the result. If anIO (an IO-like object or an object that responds to the write method) was given, the resulting JSON is written to it. If the number of nested arrays or objects exceeds limit, an ArgumentError exception is raised. This argument is similar (but not exactly the same!) to the limit argument in Marshal.dump. The default options for the gen

mod.protected_method_defined?(symbol) â true or false Instance Public methods Returns true if the named protected method is defined by mod (or its included modules and, if mod is a class, its ancestors). module A def method1() end end class B protected def method2() end end class C < B include A def method3() end end A.method_defined? :method1 #=> true C.protected_method_defined? "method1" #=> false C.protected_method_defined? "method2" #=

dump( obj [, anIO] , limit=-1 ) â anIO Class Public methods Serializes obj and all descendant objects. If anIO is specified, the serialized data will be written to it, otherwise the data will be returned as a String. If limit is specified, the traversal of subobjects will be limited to that depth. If limit is negative, no checking of depth will be performed. class Klass def initialize(str) @str = str end def say_hello @str end end (produces no output) o = Klass.ne
