Method Details

init(self, **kwargs)
(Constructor)

source code

This must be instantiated with a dict of members. The keys
are the offsets, the values are Curried Object classes that
will be instantiated when accessed.

Args:
   members: A dict of callables to use for retrieving each member. (Key
     is member name, value is a callable). Normally these are populated
     by the profile system

   struct_size: The size of this struct if known (Can be None).

Overrides: object.__init__: (inherited documentation)

to_string(self, length=None, offset=None)

source code

Returns a string containing the data part of the given allocated chunk. The length parameter is intended only for printing shorter parts of the current chunk. The offset makes only sense in combination with the length parameter and starts from the beginning of the chunk, so an offset of 4 on a 32 bit architecture starts on the size member.
