Ruby Language Metaprogramming Defining methods on instances
Example
In ruby you can add methods to existing instances of any class. This allows you to add behavior to and instance of a class without changing the behavior of the rest of the instances of that class.
class Example
def method1(foo)
puts foo
end
end
#defines method2 on object exp
exp = Example.new
exp.define_method(:method2) {puts "Method2"}
#with method parameters
exp.define_method(:method3) {|name| puts name}
