Specified by:

serviceDidShutdown in interface net.solarnetwork.service.ServiceLifecycleObserver

getSettingUid

public String getSettingUid()

Specified by:

getSettingUid in interface net.solarnetwork.settings.SettingSpecifierProvider

handlesTopic

public boolean handlesTopic(String topic)

Description copied from interface: InstructionHandler

Test if a topic is handled by this handler.

Specified by:

handlesTopic in interface InstructionHandler

Parameters:

topic - the topic

Returns:

true only if this handler can execute the job for the given topic

processInstruction

public InstructionStatus processInstruction(Instruction instruction)

Description copied from interface: InstructionHandler

Process an instruction.

Specified by:

Note that a null or empty mode argument will be treated as testing if the default mode is active, which is always true.

Specified by:

isOperationalModeActive in interface OperationalModesService

Parameters:

mode - the mode to test; the mode can be prefixed with ! to test if the given mode is not active
