Constructor Detail

PacketBuffer

public PacketBuffer(MarkerBuffer buffer,
                    java.lang.String firstHeader)
             throws java.io.IOException,
                    EOPacketStream,
                    StreamFormatException

Initialize the Packet Buffer as PacketInputStream.

Parameters:

buffer - buffer which contains the packet dataq.

firstHeader - name of the first header in this buffer. i.e. "UDP"

Throws:

java.io.IOException - any IO errors.

EOPacketStream - incase end of packet in the stream is reached.

StreamFormatException - if the input stream is not formatted correctly.

Method Detail

init

protected void init()

Initialize PacketInputStream attributes to make this hole thing work.

nextPacket

public void nextPacket()
                throws java.io.IOException,
                       EOPacketStream,
                       StreamFormatException

Prep the stream for next packet in the buffer.

Overrides:

nextPacket in class PacketInputStream

Throws:

java.io.IOException - any IO errors.

EOPacketStream - incase end of packet in the stream is reached.

StreamFormatException - if the input stream is not formatted correctly.
