Class InputStreamBuffer

java.lang.Object

org.jmrtd.io.InputStreamBuffer

public class InputStreamBuffer
extends java.lang.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.
