Type Header

object --+
         |
        Header

Known Subclasses:
Processed
Base class for all packets.

Includes all the common parts for the packets.

The class can be instansated however it will morph into
into the correct packet type once the process function
is called with data.

Example:

        p = Header(data)
        str(p)
        '<Object instance at 0x401ee50c>'
Method Summary
  __init__(self, protocol, sequence, type, length)
Create a new header object.
  __eq__(self, other)
  __repr__(self)
Return a reconisable string.
  __str__(self)
Produce a string suitable to be send over the wire.
  data_set(self, data)
Processes the data of the packet.
  fromstr(cls, data)
Look at the packet type and morph this object into the correct type. (Class method)

Instance Method Details

__init__(self, protocol, sequence, type, length)
(Constructor)

__repr__(self)
(Representation operator) 

Return a reconisable string.
Overrides:
__builtin__.object.__repr__

__str__(self)
(Informal representation operator) 

Produce a string suitable to be send over the wire.
Overrides:
__builtin__.object.__str__

data_set(self, data=None) 

Processes the data of the packet.

Class Method Details

fromstr(cls, data) 

Look at the packet type and morph this object into the
correct type.
