equals

public boolean equals(java.lang.Object o_)

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: ObjectCloneable

Returns a clone of this object.

Specified by:

clone in interface ObjectCloneable

Specified by:

clone in class Packet

_clone

Description copied from class: Packet

Returns the name of this packet.

Specified by:

getName in class Packet

_toString

public java.lang.String _toString(java.lang.String separator_)
