Instance Method Details
#find_method(*args, &block) ⇒ Object
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#>>", ...]
