/** |
|
* CCompareValidator compares the specified attribute value with another value and validates if they are equal. |
|
* |
|
* The value being compared with can be another attribute value |
|
* (specified via {@link compareAttribute}) or a constant (specified via |
|
* {@link compareValue}. When both are specified, the latter takes |
|
* precedence. If neither is specified, the attribute will be compared |
|
* with another attribute whose name is by appending "_repeat" to the source |
|
* attribute name. |
|
* |
|
* The comparison can be either {@link strict} or not. |
|
* |
|
* Starting from version 1.0.8, CCompareValidator supports different comparison operators. |
|
* Previously, it only compares to see if two values are equal or not. |
