Instance Method Details

#check(&check) ⇒ Object

This method is responsible for running some sort of test on the receiver.

It expects a block (returning true or false) to be passed. The block will be passed the receiver, so you can run comparators on it, or whatever else you like.

#check can also be called without block on truthy objects (true, false, or nil, any other object will be treated as true)

Raises:
