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

Processor, Device.open()

hasExternalOutput

public boolean hasExternalOutput()

Description copied from class: AbstractDevice

Specifies whether this device has external (implicit) output or not. Returns false by default.

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.

Specified by:

hasExternalOutput in interface Device

Overrides:

hasExternalOutput in class AbstractDevice

init

public void init()

Description copied from class: AbstractDevice

Initializes 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. By default, this method calls update(). Subclass this method if you'd like to make a specific initialization routine.

Specified by:

init in interface Processor

Overrides:

init in class AbstractDevice

See Also:

Processor.init()

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.

Specified by:

update in interface Processor

Overrides:

update in class AbstractDevice

Processor.update()
