|
|
* A mote interface represents a mote property. Typically, this is a simulated
|
|
|
|
|
* hardware peripheral such as a button or LEDs. This may also be a property
|
|
|
|
|
* that the mote itself is unaware of, for example the current position of
|
2007-01-10 14:57:42 +00:00
|
|
|
|
* the mote.

|
|
*
|
2007-01-10 14:57:42 +00:00
|
|
|
|
* Interfaces are the main way for the simulator to interact with a simulated
|
|
|
|
|
* mote.
|
2008-10-28 12:50:38 +00:00
|
|
|
|
*
|
|
|
|
|
* Each interface can be polled before and after mote ticks.
|
|
|
|
|
* This is controlled by implementing the correct Java interfaces,
|
|
|
|
|
* such as PolledBeforeActiveTicks.
