Public Functions

FlagField(const HebiInfoRef &internal, HebiInfoFlagField field)

inline explicit operator bool() const

Allows casting to a bool to check if the flag is set without directly calling has().

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

Info::FlagField& f = parent.myField();
if (f)
  std::cout << "Field has value: " << f.get() << std::endl;
else
  std::cout << "Field has no value!" << std::endl;

bool has() const

Returns true if the flag is set, false if it is cleared.
