Types

type SimpleDriver

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

func (*SimpleDriver) AddDevice

func (s *SimpleDriver) AddDevice(deviceName string, protocols map[string]models.ProtocolProperties, adminState models.AdminState) error

AddDevice is a callback function that is invoked when a new Device associated with this Device Service is added

func (*SimpleDriver) Discover

func (s *SimpleDriver) Discover() error

Discover triggers protocol specific device discovery, which is an asynchronous operation. Devices found as part of this discovery operation are written to the channel devices.

func (*SimpleDriver) HandleReadCommands

func (s *SimpleDriver) HandleReadCommands(deviceName string, protocols map[string]models.ProtocolProperties, reqs []sdkModels.CommandRequest) (res []*sdkModels.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]models.ProtocolProperties, reqs []sdkModels.CommandRequest,
	params []*sdkModels.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(sdk interfaces.DeviceServiceSDK) error

Initialize performs protocol-specific initialization for the device service.

func (*SimpleDriver) ProcessCustomConfigChanges

func (s *SimpleDriver) ProcessCustomConfigChanges(rawWritableConfig interface{})

ProcessCustomConfigChanges ...

func (*SimpleDriver) RemoveDevice

func (s *SimpleDriver) RemoveDevice(deviceName string, protocols map[string]models.ProtocolProperties) error

RemoveDevice is a callback function that is invoked when a Device associated with this Device Service is removed

func (*SimpleDriver) Start

func (s *SimpleDriver) Start() error

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).

func (*SimpleDriver) UpdateDevice

func (s *SimpleDriver) UpdateDevice(deviceName string, protocols map[string]models.ProtocolProperties, adminState models.AdminState) error

UpdateDevice is a callback function that is invoked when a Device associated with this Device Service is updated

func (*SimpleDriver) ValidateDevice

func (s *SimpleDriver) ValidateDevice(device models.Device) error
