Method Detail

hasExternalInput

public boolean hasExternalInput()

Description copied from class: AbstractDevice

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

Return false if the device is deterministic from the data & time points of view, i.e. if its output production only depend on the explicit input history (input slots) and device's initial configuration. This is the case of most of the processing devices.

Return true if output values not only depend on the values of input slots, or if output production takes undefined time. Examples of devices with external input are input peripherals and asynchronous devices.

This method is used by the reactive machine to determine if this device is triggered by its input slots, or if it must be triggered continuously (i.e. each tick). This method can also be used by the editor for the device's graphical representation.

Specified by:

hasExternalInput in interface Device

Overrides:

hasExternalInput 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.

Specified by:

update in interface Processor

Overrides:

update in class AbstractDevice
