Question

There is apparently a ruby method called method and I can’t find any docs or examples on it so far. Could someone please post a few useful annotated examples?

Answer 1

One of the best uses of the bound method object returned by Object#method is for blocks. The return result of that method can be converted to a block argument. Imagine you have:

class Converter
  def convert_item(item)
    item.transmorph
  end
end

Then you could do this

c = Converter.new
elements.map(&c.method(:convert_item))

or when you are within the convertor

elements.map(&method(:convert_item))

which IMO is more elegant than the explicit block creation syntax. It also supports to_proc so you can do this

some_object.callback = my_handler.method(:activate).to_proc

and then in some_object you can do

@callback.call(data)
