Types

type SimpleDriver

type SimpleDriver struct {
	// contains filtered or unexported fields
}

func (*SimpleDriver) HandleReadCommands

func (s *SimpleDriver) HandleReadCommands(deviceName string, protocols map[string]contract.ProtocolProperties, reqs []dsModels.CommandRequest) (res []*dsModels.CommandValue, err error)

HandleReadCommands triggers a protocol Read operation for the specified device.

func (*SimpleDriver) HandleWriteCommands

func (s *SimpleDriver) HandleWriteCommands(deviceName string, protocols map[string]contract.ProtocolProperties, reqs []dsModels.CommandRequest,
	params []*dsModels.CommandValue) error

HandleWriteCommands passes a slice of CommandRequest struct each representing a ResourceOperation for a specific device resource. Since the commands are actuation commands, params provide parameters for the individual command.

func (*SimpleDriver) Initialize

func (s *SimpleDriver) Initialize(lc logger.LoggingClient, asyncCh chan<- *dsModels.AsyncValues) error

Initialize performs protocol-specific initialization for the device service.

func (*SimpleDriver) Stop

func (s *SimpleDriver) Stop(force bool) error

Stop the protocol-specific DS code to shutdown gracefully, or if the force parameter is 'true', immediately. The driver is responsible for closing any in-use channels, including the channel used to send async readings (if supported).
