Question

I’m trying to extend the Method class along the lines of:

irb(main):008:0> class A irb(main):009:1> def a irb(main):010:2> puts 'blah' irb(main):011:2> end irb(main):012:1> end => nil irb(main):013:0> class Method irb(main):014:1> def aa irb(main):015:2> p 'hi' irb(main):016:2> end irb(main):017:1> end => nil irb(main):018:0> f = A.new => #<A:0x54ed4> irb(main):019:0> A.a NoMethodError: undefined method `a' for A:Class     from (irb):19     from :0 irb(main):020:0> f.a blah => nil irb(main):027:0> f.a.aa blah NoMethodError: undefined method `aa' for nil:NilClass     from (irb):27     from :0 

As expected, when I f.a.aa, the .aa is being executed on the return value of f.a. How do I gain access to the Method object which represents f.a?

Answer 1

With the method method… =)

f.method(:a).aa
