Robotiq::Logger Class

Minimal logging surface for Robotiq components.

Abstracts logging so the SDK can be used in three contexts:

• Production ROS 2 nodes — adapter forwards to rclcpp's logger
• Standalone CLI / bench tools — default stderr printer (no rclcpp dep)
• Unit tests — null logger or string capture

The interface is tiny by design: one method taking a level and a fully formatted message — formatting is the caller's concern.

Example — a custom sink

 void uartWrite(std::string_view) {} // stands in for a real UART driver

 

 class UartLogger : public Robotiq::Logger

 {

 public:

  void log(Level level, std::string_view message) override

  {

  if(level >= Level::Warn)

  {

  uartWrite("!! ");

  }

  uartWrite(message);

  }

 };

 

 void useCustomLogger()

 {

  auto logger = std::make_shared<UartLogger>();

  Robotiq::ConnectionConfig config;

  config.serial.port = "/dev/ttyUSB0";

  Robotiq::Gripper gripper(config, logger);

 }

Derived Classes

class	NullLogger
	A do-nothing Logger, useful in tight benchmarks or tests. More...
class	StderrLogger
	Default Logger implementation that writes to stderr. Hosted-only: it needs <iostream> and a wall clock, neither of which a freestanding target has — provide an application Logger (e.g. a UART sink) there instead. More...

Enumerations

Level

enum class Robotiq::Logger::Level

strong

Severity of a single log line.

Enumeration values

Debug	high-frequency, diagnostic detail
Info	normal operational events
Warn	recoverable, but worth a human's attention
Error	an operation failed

Public Destructor

~Logger()

virtual Robotiq::Logger::~Logger ()

virtual default

Public Member Functions

log()

virtual void Robotiq::Logger::log ( Level level, std::string_view message )

Emit a fully-formatted log line.

Parameters

level	Severity of this line.
message	The already-formatted text to log. The sink decides where it goes (stderr, UART, rclcpp, ...); it does not format, timestamp, or filter by level.
