# Forward All Arguments To Another Method
|
|
||||||
|
|
||||||
There are three types of arguments that a Ruby method can receive. Positional
|
|
||||||
arguments, keyword arguments, and a block argument.
|
|
||||||
|
|
||||||
A method that deals with all three might be defined like this:
|
|
||||||
|
|
||||||
```ruby
|
|
||||||
def forwarding_method(*args, **kwargs, &block)
|
|
||||||
# implementation
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
Now lets say we have some concrete method that we want to forward these
|
|
||||||
arguments to:
|
|
||||||
|
|
||||||
```ruby
|
|
||||||
def concrete_method(*args, **kwargs)
|
|
||||||
x = args.first || 1
|
|
||||||
key, y = kwargs.first || [:a, 2]
|
|
||||||
|
|
||||||
puts "Dealing with #{x} and key #{key}: #{y}"
|
|
||||||
|
|
||||||
yield(x, y)
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
We could forward arguments the longhand way like this:
|
|
||||||
|
|
||||||
```ruby
|
|
||||||
def forwarding_method(*args, **kwargs, &block)
|
|
||||||
concrete_method(*args, **kwargs, &block)
|
|
||||||
end
|
|
||||||
```
|
|
||||||
|
|
||||||
However, since Ruby 2.7 we have access to a shorthand "triple-dot" syntax for
|
|
||||||
forwarding all arguments.
|
|
||||||
|
|
||||||
```ruby
|
|
||||||
def forwarding_method(...)
|
|
||||||
concrete_method(...)
|
|
||||||
end
|
|
||||||
```
|
|
||||||

||||||
