* COOJA Simulator Core ("the Core") represents the entire C code part of COOJA
|
|
|
|
|
* Simulator.
|
|
|
|
|
* This part shortly consists of simulated sensors and actuators and code for
|
|
|
|
|
* communicating with the Java part.
|
|
|
|
|
*
|
|
|
|
|
* Communication with the Core should always be handled via dedicated classes
|
|
|
|
|
* (MoteType), and never directly. MoteType works as an interface giving access
|
|
|
|
|
* to variable's values given their name (through CoreComm->Lib?).
