dump(...) public

Serializes obj and all descendent 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
      def sayHello

(produces no output)

    o = Klass.new("hello\n")
    data = Marshal.dump(o)
    obj = Marshal.load(data)
    obj.sayHello   #=> "hello\n"
