ByteletSchema

Bytelets are flexible data structures used for binary serialization.

Bytelets are based on BER encoded TLV data-structures. Length calculations are maintained using dataflow-bindings.

Bytelets will be supported on language level by means of the namespace :

   namespace: "http://fiber-space.de/byteletns"
   prefix: bl

Bytelet elements will be created like this :

   bl = bl:x:
       f: 1
       g: 0x89

The bl prefix acts like a constructor.

init(self, tree, parent=None)
(Constructor)

x.__init__(...) initializes x; see x.__class__.__doc__ for signature

Parameters:

tree - A tree is a nested list of elements of the kind [TAG, ATTR, CHILDREN, TEXT]. TAG and TEXT are strings, ATTR is a dict and CHILDREN is a list of elements having the same tree structure.
parent - the parent P4D object.

Overrides: object.__init__
