Public Functions

LedField(const HebiFeedbackRef &internal, HebiFeedbackLedField field)

inline explicit operator bool() const

Allows casting to a bool to check if the LED color is set without directly calling hasColor().

This can be used as in the following (assuming ‘parent’ is a parent message, and this field is called ‘myField’)

Feedback::LedField& f = parent.myField();
if (f)
  std::cout << "Field has color!" << std::endl;
else
  std::cout << "Field has no value!" << std::endl;

bool hasColor() const: Returns true if the LED color is set, and false otherwise.

Color getColor() const: Returns the led color.
