MagicFirmwareUpdateThingHandler

public MagicFirmwareUpdateThingHandler(Thing thing)

Method Details

handleCommand

public void handleCommand(ChannelUID channelUID,
 Command command)

Description copied from interface: ThingHandler

Handles a command for a given channel.

This method is only called, if the thing has been initialized (status ONLINE/OFFLINE/UNKNOWN).

Specified by:

handleCommand in interface ThingHandler

Parameters:

channelUID - the ChannelUID of the channel to which the command was sent

command - the Command

initialize

public void initialize()

Description copied from interface: ThingHandler

Initializes the thing handler, e.g. update thing status, allocate resources, transfer configuration.

This method is only called, if the Thing contains all required configuration parameters.

Only Things with status ThingStatus.UNKNOWN, ThingStatus.ONLINE or ThingStatus.OFFLINE are considered as initialized by the framework. To achieve that, the status must be reported via ThingHandlerCallback.statusUpdated(Thing, ThingStatusInfo).

The framework expects this method to be non-blocking and return quickly. For longer running initializations, the implementation has to take care of scheduling a separate job which must guarantee to set the thing status eventually.

Any anticipated error situations should be handled gracefully and need to result in ThingStatus.OFFLINE with the corresponding status detail (e.g. *COMMUNICATION_ERROR* or *CONFIGURATION_ERROR* including a meaningful description) instead of throwing exceptions.

Specified by:

initialize in interface ThingHandler

updateFirmware

public void updateFirmware(Firmware firmware,
 ProgressCallback progressCallback)

Description copied from interface: FirmwareUpdateHandler

Updates the firmware for the physical device of the thing that is handled by this firmware update handler.

Specified by:

updateFirmware in interface FirmwareUpdateHandler

Parameters:

firmware - the new firmware to be updated (not null)

progressCallback - the progress callback to send progress information of the firmware update process (not null)

cancel

public void cancel()

Description copied from interface: FirmwareUpdateHandler

Cancels a previous started firmware update.

Specified by:

cancel in interface FirmwareUpdateHandler

isUpdateExecutable

public boolean isUpdateExecutable()

Description copied from interface: FirmwareUpdateHandler

Returns true, if this firmware update handler is in a state in which the firmware update can be executed, otherwise false (e.g. the thing is ThingStatus.OFFLINE or its status detail is already ThingStatusDetail.FIRMWARE_UPDATING.)

Specified by:

isUpdateExecutable in interface FirmwareUpdateHandler

Returns:

true, if this firmware update handler is in a state in which the firmware update can be executed, otherwise false
