/**
 * 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 'built in' functions qualify this signature (e.g. trim).
 *
 * To specify the filter method, set {@link filter} property to be the function name.
