Closure Finisher

FormFactory.php

<?php
// ...
$closureFinisher = new \TYPO3\Form\Finishers\ClosureFinisher();
$closureFinisher->setOption('closure', function($formRuntime) {
	// $formRuntime->getFormState()->getFormValues();
});
$formDefinition->addFinisher($closureFinisher);
// ...
?>

where could I get the $formRuntime. Inside the formFactory?

$redirectFinisher->setOptions(
            array('action' => 'confirmation',
               'arguments' => array (
                   'fieldNombre' => 'XXXX some value in the form XXXX'
               )

            )
        );

could I add any key to $factorySpecificConfiguration ? for example

<form:render factoryClass="TYPO3\FormExample\ExampleFormFactories\TestFactory" overrideConfiguration="{redirectTo: 'myAction'}"/>

public function build(array $factorySpecificConfiguration, $presetName)

Reutilization of the person object created by the form in several finishers

class TestFactory extends \TYPO3\Form\Factory\AbstractFormFactory {

    /**
     * @param array $factorySpecificConfiguration
     * @param $presetName
     * @return \TYPO3\Form\Core\Model\FormDefinition
     */
    public function build(array $factorySpecificConfiguration, $presetName) {
        $formPersistenceManager = new \TYPO3\Form\Persistence\YamlPersistenceManager();
        $formConfiguration = $formPersistenceManager->load('prueba');

        $arrayFormFactory = new \TYPO3\Form\Factory\ArrayFormFactory();

        $form = $arrayFormFactory->build($formConfiguration,$presetName);
        $redirectFinisher = new \TYPO3\Form\Finishers\RedirectFinisher();
        //idea code beguin
        $personObject = objectbuilder($form->getFormRuntime()->getFormSubmittedValues())
        $redirectFinisher->setOptions(
            array('action' => 'confirmation',
               'arguments' => array (
                   'Person' => $personObjecy
               )

            )
        );
       $otherFinisher->setOptions('person' => $personObject);

      // idea code end
        $form->addFinisher($redirectFinisher);
        return $form;
    }
}
?>
