and buffers input through a BufferedInputStream. |
| FSDataOutputStream | Utility that wraps a OutputStream in a DataOutputStream,
buffers output through a BufferedOutputStream and creates a checksum
file. |
| FSInputChecker | This is a generic input stream for verifying checksums for data before it is read by a user. |
| FSInputStream | FSInputStream is a generic old InputStream with a little bit of RAF-style seek ability. |
