Member Function Documentation

◆ get()

float hebi::Info::FloatField::get ( ) const

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

Definition at line 11 of file info.cpp.

◆ has()

bool hebi::Info::FloatField::has ( ) const

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

Definition at line 9 of file info.cpp.

◆ operator bool()

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