Constructor Detail

RawPacket

public RawPacket(Timeval timeval,
                 byte[] bytes,
                 int droplen)

Create a new raw packet.

Parameters:

timeval - the time the packet arrived on the device where it was captured.

bytes - the raw packet data, including headers.

droplen - the number of bytes dropped (if any) when the packet was captured.

Method Detail

getTimeval

public Timeval getTimeval()

Fetch the timeval containing the time the packet arrived on the device where it was captured.

getData

public byte[] getData()

Fetch the raw packet data.

getDroplen

public int getDroplen()

Fetch the number of bytes dropped (if any) when the packet was captured.

Bytes are dropped when the snapshot length (a ceiling on the number of bytes per packet to capture) is smaller than the actual number of bytes in the packet on the wire. In other words, when caplen exceeds snaplen, bytes are dropped and droplen will be nonzero. Otherwise, all the packet bytes were captured and droplen is zero.

toString

public java.lang.String toString()

Convert this packet to a readable string.
