| # Class: Vash (Ruby Volatile Hash) | |
| # Hash that returns values only for a short time. This is useful as a cache | |
| # where I/O is involved. The primary goal of this object is to reduce I/O | |
| # access and due to the nature of I/O being slower then memory, you should also | |
| # see a gain in quicker response times. | |
| # | |
| # For example, if Person.first found the first person from the database & cache | |
| # was an instance of Vash then the following would only contact the database for | |
| # the first iteration: |
