/**
 * 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}.
