| FileFactory | Simple strategy interface for creating new files |
| FileSpool | Interface for file based spools. |
| Spool | Class that implement this interface will spool data from the provided InputStream, and return a new InputStream to the spooled data. |
| ThresholdingSpool | Implemented by spools that switch behaviour based on the number of bytes spooled |
| BufferedFileSpool | Spool bytes via buffered file streams. |
| ByteArraySpool | A very simple spool that uses a ByteArray buffer. |
| DefaultSpoolFileFactory | Default file factory for spooling. |
| DeferredFileOutputStream | An output stream which will retain data in memory until a specified threshold is reached, and only then commit it to disk. |
| DeferredSpool | Thresholding spool that uses a DeferredSpoolFileOutputStream for spooling, allowing for a balance between memory usage and speed. |
| DeferredSpoolFileOutputStream | This specialisation of DeferredFileOutputStream may be configured with a FileFactory so that files are only created once the deferred threshold is reached. |
| SmartSpool | Spool that delegates to the overThresholdSpool immediately if InputStream::available() is greater than the threshold of the secondary Thresholding spool. |
| SpoolFileInputStream | A FileInputStream that deletes its input file when closed. |
