• DCC addresses are integrated in an object<br />
– Objects have a reference and can be translated<br />
– The object must be complete enough to use the API with as<br />
little information as possible<br />
– All information to control accessories or locomotives require<br />
and object as a reference<br />
» This allows developers to implement the sever as an<br />
object store independent of the operating system<br />
architecture.<br />
» The objects then become a “DccCookie”.<br />
• DccCookie encapsulate programming ports, command<br />
ports, decoder class and DCC addresss<br />
• The DCC cookie becomes the reference token for system<br />
calls and can easily be validated<br />
