Method Detail

safeRead

public static int safeRead(java.io.InputStream inputStream,
                           byte[] buffer)
                    throws java.io.IOException

Read a number of bytes from the stream and store it in the buffer, and fix the problem with "incomplete" reads by doing another read if we don't have all of the data yet.

Parameters:

inputStream - the input stream to read from

buffer - where to store the data

Returns:

the number of bytes read (should be == length if we didn't hit EOF)

Throws:

java.io.IOException - if an error occurs while reading the stream

eofIsNext

public static boolean eofIsNext(RawPacket rawPacket)

Checks whether the next packet is EOF.

Parameters:

rawPacket - the raw packet

Returns:

true if the packet is an EOF packet

isErrorPacket

public static boolean isErrorPacket(RawPacket rawPacket)
