Examples of org.apache.jackrabbit.util.TransientFileFactory

org.apache.jackrabbit.util.TransientFileFactory
The TransientFileFactory utility class can be used to create transient files, i.e. temporary files that are automatically removed once the associated File object is reclaimed by the garbage collector.
File deletion is handled by a low-priority background thread.

                    } else if (len + read > BinaryQValue.MAX_BUFFER_SIZE) {

                        // create temp file and spool buffer contents
                        TransientFileFactory fileFactory = TransientFileFactory.getInstance();
                        spoolFile = fileFactory.createTransientFile("bin", null, null);
                        out = new FileOutputStream(spoolFile);
