Example 6 with FileOwnerAttributeView

use of java.nio.file.attribute.FileOwnerAttributeView in project j2objc by google.

the class Files method setOwner.

/**
 * Updates the file owner.
 *
 * <p> The {@code path} parameter is associated with a file system that
 * supports {@link FileOwnerAttributeView}. This file attribute view provides
 * access to a file attribute that is the owner of the file.

 * <p> <b>Usage Example:</b>
 * Suppose we want to make "joe" the owner of a file:
 * <pre>
 *     Path path = ...
 *     UserPrincipalLookupService lookupService =
 *         provider(path).getUserPrincipalLookupService();
 *     UserPrincipal joe = lookupService.lookupPrincipalByName("joe");
 *     Files.setOwner(path, joe);

 * @param   path
 *          The path to the file
 * @param   owner
 *          The new file owner
