Example 11 with FileGrp

use of org.mycore.mets.model.files.FileGrp in project mycore by MyCoRe-Org.

the class MCRMetsSave method updateFiles.

/**
 * Call this method to update the mets.xml if files of the derivate have changed. Files will be added or removed
 * from the mets:fileSec and mets:StructMap[@type=PHYSICAL]. The mets:structLink part will be rebuild after.
 *
 * <p>This method takes care of the group assignment. For example: image files will be added to the MASTER
 * group and ALTO files to the ALTO group. It will also bundle files with the same name e.g. sample1.tiff and
 * alto/sample1.xml to the same physical struct map div.</p>
 *
 * <p><b>Important:</b> This method does not update the mets.xml in the derivate, its just updating the given mets
 * instance.</p>
 *
 * @param mets the mets to update
 * @param derivatePath path to the derivate -&gt; required for looking up new files
 * @throws IOException derivate couldn't be read
