Member functions

Function name	Return type	Input type	Description
device() const	uint32	void	Returns the current value of device. If the device is not set, returns 0.
set_device()	void	uint32	Sets the value of device. After calling this, device() will return value.
clear_device()	void	void	Clears the value of device. After calling this, device() will return the empty string/empty bytes.
device_address()	uint32	void	Returns the current value of device_address. If the device_address is not set, returns 0.
set_device_address()	void	uint32	Sets the value of device_address. After calling this, device_address() will return value.
clear_device_address()	void	void	Clears the value of device_address. After calling this, device_address() will return 0.
timeout()	uint32	void	Returns the current value of timeout. If the timeout is not set, returns 0.
set_timeout()	void	uint32	Sets the value of timeout. After calling this, timeout() will return value.
clear_timeout()	void	void	Clears the value of timeout. After calling this, timeout() will return 0.
has_data() const	bool	void	Returns true if data is set.
data()	const I2CData&	void	Returns the current value of data. If data is not set, returns a I2CData with none of its fields set (possibly data::default_instance()).
mutable_data()	I2CData *	void	Returns a pointer to the mutable I2CData object that stores the field's value. If the field was not set prior to the call, then the returned I2CData will have none of its fields set (i.e. it will be identical to a newly-allocated I2CData). After calling this, has_data() will return true and data() will return a reference to the same instance of I2CData.
clear_data()	void	void	Clears the value of the field. After calling this, has_data() will return false and data() will return the default value.
set_allocated_data()	void	I2CData *	Sets the I2CData object to the field and frees the previous field value if it exists. If the I2CData pointer is not NULL, the message takes ownership of the allocated I2CData object and has_ I2CData() will return true. Otherwise, if the data is NULL, the behavior is the same as calling clear_data().
release_data()	I2CData *	void	Releases the ownership of the field and returns the pointer of the I2CData object. After calling this, caller takes the ownership of the allocated I2CData object, has_data() will return false, and data() will return the default value.
