-/**
- * TBaseValidator class
- *
- * TBaseValidator serves as the base class for validator controls.
- *
- * Validation is performed when a postback control, such as a TButton, a TLinkButton
- * or a TTextBox (under AutoPostBack mode) is submitting the page and
- * its <b>CausesValidation</b> property is true.
- * You can also manually perform validation by calling {@link TPage::validate()}.
- * The input control to be validated is specified by {@link setControlToValidate ControlToValidate}.
- *
- * Validator controls always validate the associated input control on the serve side.
- * In addition, if {@link getEnableClientScript EnableClientScript} is true,
- * validation will also be performed on the client-side using javascript.
- * Client-side validation will validate user input before it is sent to the server.
- * The form data will not be submitted if any error is detected. This avoids
- * the round-trip of information necessary for server-side validation.
- *
- * You can use multiple validator controls to validate a single input control,
- * each responsible for validating against a different criteria.
- * For example, on a user registration form, you may want to make sure the user
- * enters a value in the username text box, and the input must consist of only word
- * characters. You can use a {@link TRequiredFieldValidator} to ensure the input
- * of username and a {@link TRegularExpressionValidator} to ensure the proper input.
- *
- * If an input control fails validation, the text specified by the {@link setErrorMessage ErrorMessage}
- * property is displayed in the validation control. However, if the {@link setText Text}
- * property is set, it will be displayed instead. If both {@link setErrorMessage ErrorMessage}
- * and {@link setText Text} are empty, the body content of the validator will
- * be displayed. Error display is controlled by {@link setDisplay Display} property.
- *
- * You can also customized the client-side behaviour by adding javascript
- * code to the subproperties of the {@link getClientSide ClientSide}
- * property. See quickstart documentation for further details.
- *
- * You can also place a {@link TValidationSummary} control on a page to display error messages
- * from the validators together. In this case, only the {@link setErrorMessage ErrorMessage}
- * property of the validators will be displayed in the {@link TValidationSummary} control.
- *
- * Validators can be partitioned into validation groups by setting their
- * {@link setValidationGroup ValidationGroup} property. If the control causing the
- * validation also sets its ValidationGroup property, only those validators having
- * the same ValidationGroup value will do input validation.
- *
- * Note, the {@link TPage::getIsValid IsValid} property of the current {@link TPage}
- * instance will be automatically updated by the validation process which occurs
- * after {@link TPage::onLoad onLoad} of {@link TPage} and before the postback events.
- * Therefore, if you use the {@link TPage::getIsValid()} property in
- * the {@link TPage::onLoad()} method, you must first explicitly call
- * the {@link TPage::validate()} method.
- *
- * <b>Notes to Inheritors</b> When you inherit from TBaseValidator, you must
- * override the method {@link evaluateIsValid}.

+ * TBaseValidator class
+ *
+ * TBaseValidator serves as the base class for validator controls.
+ *
+ * Validation is performed when a postback control, such as a TButton, a TLinkButton
+ * or a TTextBox (under AutoPostBack mode) is submitting the page and
+ * its <b>CausesValidation</b> property is true.
+ * You can also manually perform validation by calling {@link TPage::validate()}.
+ * The input control to be validated is specified by {@link setControlToValidate ControlToValidate}.
+ *
+ * Validator controls always validate the associated input control on the serve side.
+ * In addition, if {@link getEnableClientScript EnableClientScript} is true,
+ * validation will also be performed on the client-side using javascript.
+ * Client-side validation will validate user input before it is sent to the server.
+ * The form data will not be submitted if any error is detected. This avoids
+ * the round-trip of information necessary for server-side validation.
+ *
+ * You can use multiple validator controls to validate a single input control,
+ * each responsible for validating against a different criteria.
+ * For example, on a user registration form, you may want to make sure the user
+ * enters a value in the username text box, and the input must consist of only word
+ * characters. You can use a {@link TRequiredFieldValidator} to ensure the input
+ * of username and a {@link TRegularExpressionValidator} to ensure the proper input.
+ *
+ * If an input control fails validation, the text specified by the {@link setErrorMessage ErrorMessage}
+ * property is displayed in the validation control. However, if the {@link setText Text}

+ * be displayed. Error display is controlled by {@link setDisplay Display} property.
+ *
+ * You can also customized the client-side behaviour by adding javascript
+ * code to the subproperties of the {@link getClientSide ClientSide}
+ * property. See quickstart documentation for further details.
+ *
+ * You can also place a {@link TValidationSummary} control on a page to display error messages
+ * from the validators together. In this case, only the {@link setErrorMessage ErrorMessage}
+ * property of the validators will be displayed in the {@link TValidationSummary} control.
+ *
+ * Validators can be partitioned into validation groups by setting their
+ * {@link setValidationGroup ValidationGroup} property. If the control causing the
+ * validation also sets its ValidationGroup property, only those validators having
+ * the same ValidationGroup value will do input validation.
+ *
+ * Note, the {@link TPage::getIsValid IsValid} property of the current {@link TPage}
+ * instance will be automatically updated by the validation process which occurs
+ * after {@link TPage::onLoad onLoad} of {@link TPage} and before the postback events.
+ * Therefore, if you use the {@link TPage::getIsValid()} property in
+ * the {@link TPage::onLoad()} method, you must first explicitly call
+ * the {@link TPage::validate()} method.
