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:
