find_method(*args, &block) click to toggle source

An alternative interface to the functionality of MethodFinder.find. Also allows to test for state other than the return value of the method.

%w[a b c].find_method { |a| a.unknown(1) ; a == %w[a c] }
#=> ["Array#delete_at", "Array#slice!"]
10.find_method { |n| n.unknown(3) == 1 }
#=> ["Fixnum#%", "Fixnum#<=>", "Fixnum#>>", ...]

Inside find_method's block, the receiver is available as block argument and the special method unknown is used as a placeholder for the desired method.

find_method can be called without passing a block. This is the same as calling MethodFinder.find.

10.find_method(1, 3)
#=> ["Fixnum#%", "Fixnum#<=>", "Fixnum#>>", ...]
# File lib/methodfinder.rb, line 25
def find_method(*args, &block)
  return MethodFinder.find(self, *args) unless block_given?
  MethodFinder.find_unknown(self, &block)
end
