Detailed Description

Type Length Value Structure

this structure holds arbitrary type of data this is used in particular for the slice header

Note: a tlv is a memory_file, that way it holds the *V*alue and *L*ength of the data. Only the *T*ype field needs to be added to the memory_file datastructure

Definition at line 45 of file tlv.hpp.

The documentation for this class was generated from the following file:
