O_TMPFILE backed temporary files for Java.

What is O_TMPFILE?

O_TMPFILE is a Linux-specific flag for open(), that allows creation of already-unlinked temporary files, that don't need to be explicitly removed via unlink. This means that you could create a temp file without name. This is wrapper library to use O_TMPFILE from Java.

How to Use?

SecureTempFile tmp = new SecureTempFile();

// Create and write temp file without giving a name
try (FileOutputStream fs = new FileOutputStream(stf.getFileDescriptor())) {
  fs.write("foo".getBytes());
}

// Optionally set the file name
String tempFilePath = SecureTempFile.TEMP_DIR + File.separator + "my-temp-file.tmp";
tmp.setName(tempFilePath);
