A common issue when receiving data either electronically or from user input is verifying the integrity of the data. This work is repetitive and becomes even more complicated when different sets of validation rules need to be applied to the same set of data based on locale. Error messages may also vary by locale. This package addresses some of these issues to speed development and maintenance of validation rules.
Validator provides two distinct sets of functionality:
Your validation methods are plugged into the engine and executed against your data. Often, these methods use resources specific to one application or framework so Commons Validator doesn't directly provide pluggable validator actions. However, it does have a set of common validation methods (email addresses, dates, URLs, etc.) that help in creating pluggable actions.
In order to use the Validator, the following basic steps are required:
The commons mailing lists act as the main support forum. The user list is suitable for most library usage queries. The dev list is intended for the development discussion. Please remember that the lists are shared between all commons components, so prefix your email by [validator].
