Constructor Detail

BufferedSocketInputStream

public BufferedSocketInputStream(SocketImpl impl)
                          throws IOException

creates a BufferedSocketInputStream with a buffersize of SocketOptions.SO_SNDBUF

Parameters:

impl - a SocketImpl

Throws:

IOException - if size <= 0

BufferedSocketInputStream

public BufferedSocketInputStream(SocketImpl impl,
                                 int size)
                          throws IOException

creates a BufferedSocketInputStream

Parameters:

impl - a SocketImpl

size - size of the buffer

Throws:

IOException - if size <= 0

Method Detail

getAck

public int getAck()

gets the address of the last part of the buffer that can be acknowledged

Returns:

the address of the last part of the buffer that can be acknowledged

addPacket

public void addPacket(TCPPacket packet)
               throws NetSimException

adds a TCP Packet into the Inputstreams buffer

Parameters:

packet - a TCP Packet

Throws:

NetSimException - if the packet can't be added to the buffer (the buffer is full)
