Example 2 with FileTypeDetector

use of java.nio.file.spi.FileTypeDetector in project mycore by MyCoRe-Org.

the class MCRContentTypes method probeContentType.

/**
 * Probes the content type of a file.
 *
 * Same as {@link Files#probeContentType(Path)} but uses context class loader.
 * @param path
 *              the path to the file to probe
 * @return The content type of the file, or null if the content type cannot be determined
 * @throws IOException if an I/O error occurs
 */
