TYPO3/ExtBase: Get upload path from TCA

gistfile1.php

<?php

class SomeClass{

	protected function getUploadPath($table, $field) {
		global $TCA;

		$cObj = $this->configurationManager->getContentObject();

		t3lib_div::loadTCA($table);
		return $cObj->typoLink_URL(array(
			'parameter' => trim($TCA[$table]['columns'][$field]['config']['uploadfolder'], '/') . '/'
		));
	}

}

In a pre-FAL situation I use this snippet to get the upload path of a file from the TCA record of the table.
