With no arguments, raises the exception in $!
or raises a
RuntimeError
if $!
is nil
. With a
single String
argument, raises a RuntimeError
with the string as a message. Otherwise, the first parameter should be the
name of an Exception
class (or an object that returns an
Exception
object when sent an exception
message).
The optional second parameter sets the message associated with the
exception, and the third parameter is an array of callback information.
Exceptions are caught by the rescue
clause of
begin...end
blocks.
