Constructor Detail

TCPApplicationPacket

public TCPApplicationPacket(int size)

Creates a new TCPAPP packet of a given size.

Parameters:

size - The number of bytes in the packet.

TCPApplicationPacket

public TCPApplicationPacket(TCPApplicationPacket packet)

Creates a new TCPApplication packet that is a copy of a given packet.

Parameters:

packet - The packet to replicate.

Method Detail

setData

public void setData(byte[] data)

Description copied from class: IPPacket

Sets the raw packet byte array. Although this method would appear to violate object-oriented principles, it is necessary to implement efficient packet processing. You don't necessarily want to allocate a new IPPacket and data buffer every time a packet arrives and you need to be able to wrap packets from APIs that supply them as byte arrays.

Overrides:

setData in class TCPPacket

Parameters:

data - The raw packet byte array to wrap.

getApplicationString

public java.lang.String[] getApplicationString(int size)
