Method Detail

open

public Processor open(OpenContext context)

Description copied from class: AbstractDevice

Subclass this method if you want to specialize data processing, or if you want to perform some initializations before running the device.

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.

Specified by:

open in interface Device

Overrides:

open in class AbstractDevice

update

public void update()

Description copied from class: AbstractDevice

Updates device's output values.

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

update in interface Processor

Overrides:

update in class AbstractDevice
