Specifying a Regular Expression
When specifying a regular expression, the regular expression can be either a RKRegex object or a NSString containing the text of a regular expression. When specified as a NSString, as determined by sending isKindOfClass:, the receiver will convert the string to a RKRegex object via regexWithRegexString:options:.
Determining if an Object Matches a Regular Expression
Objects are sent isMatchedByRegex: to determine whether or not they are matched by the specified regular expression.
