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.

public boolean getScreenCoordinates()

AbstractDevice
Return false if the device has no border effects. Most of input and processing devices are in this case.
Return true if the device has border effects, such as graphical feedback, or control of some external value. Examples of devices with external output are application-interfacing devices and all user feedback devices.
This method can be used by the editor for the device's graphical representation. However there is at now no clear definition of what is external output.
