◆ operator bool()

template<typename T>
hebi::Info::EnumField< T >::operator bool ( ) const
inlineexplicit

Allows casting to a bool to check if the field has a value 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::EnumField& f = parent.myField();
if (f)
std::cout << "Field has value: " << f.get() << std::endl;
else
std::cout << "Field has no value!" << std::endl;

◆ has()

template<typename T>
bool hebi::Info::EnumField< T >::has ( ) const
inline

True if (and only if) the field has a value.

◆ get()

template<typename T>
T hebi::Info::EnumField< T >::get ( ) const
inline

If the field has a value, returns that value; otherwise, returns a default.
