public Processor open(OpenContext context)
AbstractDevice
By default, open() does nothing and returns the device itself as the Processor (or null if it is not openable): AbstractDevice implements both Device and Processor interfaces, so that you can add processing code directly into the device.
If you want to add specialization features, subclass this method to return a specific processor implementation depending on your device configuration.
Example :
public Processor getProcessor() {
if (super.open() == null)
return null;
// Select the right processor
if (in2.isValid()) {
return new twoParamProcessor(in1, in2, out);
else
return new oneParamProcessor(in1, out);
}
In this method, you may also perform all necessary pre-running initialization. If initialization fails, return null even if isOpenable() returns true.
In all cases, return null if isOpenable() returns false.

AbstractDevice
Subclass init() and update() methods if you want the device to process the data itself. Otherwise, subclass getProcessor() method to use extern processors.
