void hebi::Command::FloatField::clear

(

)

Removes any currently set value for this field.

)

const

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

bool hebi::Command::FloatField::has

(

)

const

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

Definition at line 21 of file command.cpp.

hebi::Command::FloatField::operator bool ( ) const

explicit

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')

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

void hebi::Command::FloatField::set

(

float

value

)

Sets the field to a given value.
