try:
instance_methods
methods

example:

irb(main):001:0> class Foo
irb(main):002:1>   def foo
irb(main):003:2>     "foo"
irb(main):004:2>   end
irb(main):005:1> end
irb(main):010:0> Foo.instance_methods
=> ["clone", "display", "protected_methods", "freeze", 
"instance_variable_set", "foo", "is_a?", "type", "methods", "method",

"eql?", "dup", "hash", "private_methods", "nil?", "tainted?", "class",

"instance_variable_get", "object_id", "kind_of?", "inspect", "taint", 
"frozen?", "==", "public_methods", "id", "respond_to?", "===", "equal?", 
"to_a"]
irb(main):011:0> f = Foo.new
=> #<Foo:0x884ac>
irb(main):012:0> f.methods
=> ["clone", "display", "protected_methods", "freeze",
