Example 7 with MCRUsageException

use of org.mycore.common.MCRUsageException in project mycore by MyCoRe-Org.

the class MCRFileImportExport method importFiles.

/**
 * Imports the contents of a local file or directory into the MyCoRe Internal Filesystem. If the local object is a file, a MCRFile with the same name will
 * be created or updated in the given MCRDirectory. If the local object is a directory, all contained subdirectories and files will be imported into the
 * given MCRDirectory. That means that after finishing this method, the complete directory structure will have been imported and mapped from the local
 * filesystem's structure. The method checks the contents of each local file to be imported. If the file's content has not changed for existing files, the
 * internal MCRFile will not be updated. If an internal directory is updated from a local directory, new files will be added, existing files will be updated
 * if necessary, but files that already exist in the given MCRDirectory but not in the local filesystem will be kept and will not be deleted.
 *
 * @param local
 *            the local file or directory
 * @param dir
 *            an existing MCRDirectory where to store the imported contents of the local filesystem.
