public interface BulkDeleteSource

Interface for bulk deletion. Filesystems which support bulk deletion should implement this interface and MUST also declare their support in the path capability CommonPathCapabilities.BULK_DELETE. Exporting the interface does not guarantee that the operation is supported; returning a BulkDelete object from the call createBulkDelete(Path) is.
