/**
 * This class encapsulates a complete *Form Definition*, with all of its pages,
 * form elements, validation rules which apply and finishers which should be
 * executed when the form is completely filled in.
 *
 * It is *not modified* when the form executes.
 *
 * The Anatomy Of A Form
 * =====================
 *
 * A FormDefinition consists of multiple *Page* ({@link Page}) objects. When a
 * form is displayed to the user, only one *Page* is visible at any given time,
 * and there is a navigation to go back and forth between the pages.
 *
 * A *Page* consists of multiple *FormElements* ({@link FormElementInterface}, {@link AbstractFormElement}),
 * which represent the input fields, textareas, checkboxes shown inside the page.
 *
 * *FormDefinition*, *Page* and *FormElement* have *identifier* properties, which
 * must be unique for each given type (i.e. it is allowed that the FormDefinition and
 * a FormElement have the *same* identifier, but two FormElements are not allowed to
 * have the same identifier.
 *
 * Simple Example
 * --------------
 *
 * Generally, you can create a FormDefinition manually by just calling the API
 * methods on it, or you use a *Form Definition Factory* to build the form from
 * another representation format such as YAML.
 *
 * /---code php
 * $formDefinition = GeneralUtility::makeInstance(FormDefinition::class, 'myForm');
 *
 * $page1 = GeneralUtility::makeInstance(Page::class, 'page1');
 * $formDefinition->addPage($page);
 *
 * $element1 = GeneralUtility::makeInstance(GenericFormElement::class, 'title', 'Textfield'); # the second argument is the type of the form element
 * $page1->addElement($element1);
 * \---
 *
 * Creating a Form, Using Abstract Form Element Types
 * =====================================================
 *
 * While you can use the {@link FormDefinition::addPage} or {@link Page::addElement}
 * methods and create the Page and FormElement objects manually, it is often better
 * to use the corresponding create* methods ({@link FormDefinition::createPage}
 * and {@link Page::createElement}), as you pass them an abstract *Form Element Type*
 * such as *Text* or *Page*, and the system **automatically
 * resolves the implementation class name and sets default values**.
 *
 * So the simple example from above should be rewritten as follows:
 *
 * /---code php
 * $prototypeConfiguration = []; // We'll talk about this later
 *
 * $formDefinition = GeneralUtility::makeInstance(FormDefinition::class, 'myForm', $prototypeConfiguration);
 * $page1 = $formDefinition->createPage('page1');
 * $element1 = $page1->addElement('title', 'Textfield');
 * \---
 *
 * Now, you might wonder how the system knows that the element *Textfield*
 * is implemented using a GenericFormElement: **This is configured in the $prototypeConfiguration**.
 *
 * To make the example from above actually work, we need to add some sensible
 * values to *$prototypeConfiguration*:
 *
 * <pre>
 * $prototypeConfiguration = [
 *   'formElementsDefinition' => [
 *     'Page' => [
 *       'implementationClassName' => 'TYPO3\CMS\Form\Domain\Model\FormElements\Page'
 *     ],
 *     'Textfield' => [
 *       'implementationClassName' => 'TYPO3\CMS\Form\Domain\Model\FormElements\GenericFormElement'
 *     ]
 *   ]
 * ]
 * </pre>
 *
 * For each abstract *Form Element Type* we add some configuration; in the above
 * case only the *implementation class name*. Still, it is possible to set defaults
 * for *all* configuration options of such an element, as the following example
 * shows:
 *
 * <pre>
 * $prototypeConfiguration = [
 *   'formElementsDefinition' => [
 *     'Page' => [
 *       'implementationClassName' => 'TYPO3\CMS\Form\Domain\Model\FormElements\Page',
 *       'label' => 'this is the label of the page if nothing is specified'
 *     ],
 *     'Textfield' => [
 *       'implementationClassName' => 'TYPO3\CMS\Form\Domain\Model\FormElements\GenericFormElement',
 *       'label' = >'Default Label',
 *       'defaultValue' => 'Default form element value',
 *       'properties' => [
 *         'placeholder' => 'Text which is shown if element is empty'
 *       ]
 *     ]
 *   ]
 * ]
 * </pre>
 *
 * Using Preconfigured $prototypeConfiguration
 * ---------------------------------
 *
 * Often, it is not really useful to manually create the $prototypeConfiguration array.
 *
 * Most of it comes pre-configured inside the YAML settings of the extensions,
 * and the {@link \TYPO3\CMS\Form\Domain\Configuration\ConfigurationService} contains helper methods
 * which return the ready-to-use *$prototypeConfiguration*.
 *
 * Property Mapping and Validation Rules
 * =====================================
 *
 * Besides Pages and FormElements, the FormDefinition can contain information
 * about the *format of the data* which is inputted into the form. This generally means:
 *
 * - expected Data Types
 * - Property Mapping Configuration to be used
 * - Validation Rules which should apply
 *
 * Background Info
 * ---------------
 * You might wonder why Data Types and Validation Rules are *not attached
 * to each FormElement itself*.
 *
 * If the form should create a *hierarchical output structure* such as a multi-
 * dimensional array or a PHP object, your expected data structure might look as follows:
 * <pre>
 * - person
 * -- firstName
 * -- lastName
 * -- address
 * --- street
 * --- city
 * </pre>
 *
 * Now, let's imagine you want to edit *person.address.street* and *person.address.city*,
 * but want to validate that the *combination* of *street* and *city* is valid
 * according to some address database.
 *
 * In this case, the form elements would be configured to fill *street* and *city*,
 * but the *validator* needs to be attached to the *compound object* *address*,
 * as both parts need to be validated together.
 *
 * Connecting FormElements to the output data structure
 * ====================================================
 *
 * The *identifier* of the *FormElement* is most important, as it determines
 * where in the output structure the value which is entered by the user is placed,
 * and thus also determines which validation rules need to apply.
 *
 * Using the above example, if you want to create a FormElement for the *street*,
 * you should use the identifier *person.address.street*.
 *
 * Rendering a FormDefinition
 * ==========================
 *
 * In order to trigger *rendering* on a FormDefinition,
 * the current {@link \TYPO3\CMS\Extbase\Mvc\Request} needs to be bound to the FormDefinition,
 * resulting in a {@link \TYPO3\CMS\Form\Domain\Runtime\FormRuntime} object which contains the *Runtime State* of the form
 * (such as the currently inserted values).
 *
 * /---code php
 * # $currentRequest and $currentResponse need to be available, f.e. inside a controller you would
 * # use $this->request and $this->response; inside a ViewHelper you would use $this->controllerContext->getRequest()
 * # and $this->controllerContext->getResponse()
 * $form = $formDefinition->bind($currentRequest, $currentResponse);
 *
 * # now, you can use the $form object to get information about the currently
 * # entered values into the form, etc.
 * \---
 *
 * Refer to the {@link \TYPO3\CMS\Form\Domain\Runtime\FormRuntime} API doc for further information.
 *
 * Scope: frontend
 * **This class is NOT meant to be sub classed by developers.**
