All Implemented Interfaces:

FormValidator

public class ViewSettingsFormValidator
extends Object
implements FormValidator

A FormValidator implementation for validating the dialog with view settings.

This class performs specific validations that involve multiple fields and thus cannot be achieved by simple Validator implementations. The following validation rules are implemented:

• If the check box for filtering file types is checked, at least one file type must have been selected.
• If the check box for filtering by file size is checked, a valid file minimum size must have been entered.
• If the check box for filtering by file date is checked, the from date and/or the to date must have been provided.
