bool efl::eina::operator== | ( | optional< T > const & | lhs, |
optional< T > const & | rhs | ||
) |
Check if both eina::optional
object are equal.
lhs | eina::optional object at the left side of the expression. |
rhs | eina::optional object at the right side of the expression. |
true
if both are objects are disengaged of if both objects are engaged and contain the same value, false
in all other cases. bool efl::eina::operator!= | ( | optional< T > const & | lhs, |
optional< T > const & | rhs | ||
) |
Check if the eina::optional
objects are different.
lhs | eina::optional object at the left side of the expression. |
rhs | eina::optional object at the right side of the expression. |
bool efl::eina::operator< | ( | optional< T > const & | lhs, |
optional< T > const & | rhs | ||
) |
Less than comparison between eina::optional
objects.
lhs | eina::optional object at the left side of the expression. |
rhs | eina::optional object at the right side of the expression. |
true
if both objects are engaged and the contained value of lhs
is less than the contained value of rhs
, or if only lhs
is disengaged. In all other cases returns false
. bool efl::eina::operator<= | ( | optional< T > const & | lhs, |
optional< T > const & | rhs | ||
) |
Less than or equal comparison between eina::optional
objects.
lhs | eina::optional object at the left side of the expression. |
rhs | eina::optional object at the right side of the expression. |
true
if lhs
is disengaged or if both objects are engaged and the contained value of lhs
is less than or equal to the contained value of rhs
. In all other cases returns false
. bool efl::eina::operator> | ( | optional< T > const & | lhs, |
optional< T > const & | rhs | ||
) |
More than comparison between eina::optional
objects.
lhs | eina::optional object at the left side of the expression. |
rhs | eina::optional object at the right side of the expression. |
true
if both objects are engaged and the contained value of lhs
is more than the contained value of rhs
, or if only rhs
is disengaged. In all other cases returns false
. bool efl::eina::operator>= | ( | optional< T > const & | lhs, |
optional< T > const & | rhs | ||
) |
More than or equal comparison between eina::optional
objects.
lhs | eina::optional object at the left side of the expression. |
rhs | eina::optional object at the right side of the expression. |
true
if rhs
is disengaged or if both objects are engaged and the contained value of lhs
is more than or equal to the contained value of rhs
. In all other cases returns false
.
