Contains various facilities for dealing with LLRP schemas
Produces LLRP schema objects. It is safe to create as many of these as you need... only one object is created (and cached) per filename string.
use RFID::LLRP::Schema;
my ($llrp, $lookup_msg, $lookup_param, $lookup_enum) =
read_schema ('./ReaderDef.xml');
read_schema($path)Returns a reference to the llrp binary format descriptor hash, and references to message, parameter and enumeration lookup tables.
The best way to understand these data structures is to print them using Data::Dumper. Builder.pm just peers directly into these tables as a ``layer'' and it seems hard, inefficient and more importantly, pointless (tight coupling with a layered API or tight coupling with a data structure, any way you go you will still have tight coupling) to obfuscate it with an API. If the layout doesn't suit your needs, build additional indexing data structures.
read_schema returns

a reference to the LLRP schema\%registry
A reference for looking up (mangled) LLRP types, including extensions
