/**
* CTypeValidator verifies if the attribute is of the type specified by {@link type}.
*
* The following data types are supported:
* <ul>
* <li><b>integer</b> A 32-bit signed integer data type.</li>
* <li><b>float</b> A double-precision floating point number data type.</li>
* <li><b>string</b> A string data type.</li>
* <li><b>array</b> An array value. </li>
* <li><b>date</b> A date data type.</li>
* <li><b>time</b> A time data type (available since version 1.0.5).</li>
* <li><b>datetime</b> A date and time data type (available since version 1.0.5).</li>
* </ul>
*
* For <b>date</b> type, the property {@link dateFormat}
* will be used to determine how to parse the date string. If the given date
* value doesn't follow the format, the attribute is considered as invalid.
*
* Starting from version 1.1.7, we have a dedicated date validator {@link CDateValidator}.
* Please consider using this validator to validate a date-typed value.
