duplicate

public void duplicate(java.lang.Object source_)

Description copied from class: DrclObj

opies the content of the source_ object to this object. he subclass must implement this method to realize DrclObj.clone().

Overrides:

duplicate in class Packet

equals

Description copied from class: Packet

Returns true if that_ is a packet, and its packet size, header size and the encapsulated object are all equal to those of this packet.

Overrides:

equals in class Packet

clone

public java.lang.Object clone()

Description copied from interface: PacketWrapper

Returns a clone of this wrapper instance.

Overrides:

clone in class DrclObj

_clone

public InetPacket _clone()

Returns a clone of this packet. The difference between this method and clone() is that in this method, the reference of the encapsulated object is copied instead of the object itself.

public java.lang.String getName()

Description copied from class: Packet

Returns the name of this packet.
