InputStreamBuffer (JMRTD 0.7.5 API)

java.lang.Object
- org.jmrtd.io.InputStreamBuffer

```
public class InputStreamBuffer
extends Object
```
Buffers an inputstream (whose length is known in advance) and can supply clients with fresh "copies" of that inputstream served from the buffer. NOTE: the original inputstream should no longer be read from, clients should only read bytes from the sub-inputstreams.
