/**
* CFilterValidator transforms the data being validated based on a filter.
*
* CFilterValidator is actually not a validator but a data processor.
* It invokes the specified filter method to process the attribute value
* and save the processed value back to the attribute. The filter method
* must follow the following signature:
* <pre>
* function foo($value) {...return $newValue; }
* </pre>
* Many PHP functions qualify this signature (e.g. trim).
*
* To specify the filter method, set {@link filter} property to be the function name.
