public class MultiByteArrayInputStream
This class allows you to treat a list of byte arrays as a single NonblockingInputStream. This is helpful for parsing data contained within network packets, where the payload for one ADU might be spread across multiple packets. This is a *nonblocking* interface; if you attempt to read data from it, and none is available, it will return immediately.
Constructor Summary | |
---|---|
MultiByteArrayInputStream()
Create an empty MultiByteArrayInputStream. |
|
MultiByteArrayInputStream(byte[][] barr)
Create a MultiByteArrayInputStream with the given array of byte arrays. |
Method Summary | |
---|---|
void |
addArray(byte[] barr)
Add an array to this MultiByteArrayInputStream. |
int |
available()
Return the number of bytes available for reading. |
void |
clear()
Reset this input stream - clear all internal data and pointers to a fresh initialized state. |
void |
close()
Close this stream. |
void |
mark(int readlimit)
Set the stream's mark to the current position. |
boolean |
markSupported()
Returns true, since mark() and reset() are supported. |
int |
nbRead()
Read the next byte from this stream. |
int |
numArrays()
Return the number of bytes registered. |
int |
read()
Read the next byte from this stream. |
int |
read(byte[] b)
Read data from this input stream into the given byte array starting at offset 0 for b.length bytes. |
int |
read(byte[] b,
int off,
int len)
Read data from this input stream into the given byte array starting at offset 'off' for 'len' bytes. |
void |
reset()
Returns the stream to the position of the previous mark(). |
long |
skip(long n)
Skip n bytes in this stream; returns the number of bytes actually skipped (which may be less than the number requested). |
