A qualified value representing a periodic table block.
Constructs a new defined block.
source | The initial definition. |
qualifier | The qualification of the initial value. |
Constructs a new undefined or default block.
qualifier | The qualification of the initial value. |
|
virtual |
Compares two qualified values.
Derived classes may override this function, first calling compare_base, and use a dynamic_cast to check other.
other | The qualified value for comparison. |
-1
if this value is undefined or is less than other
; 0
if the values are equal; or 1
if other
is undefined or this value is greater than other
. Reimplemented from Elemental::value_base.

protectedvirtual |
Returns a localized text representation of a defined value.
Derived classes must implement this function to produce a text representation based on the format. It will be called by get_string(), which will then decorate its output as appropriate for the current qualifier. If has_value() is false
, the behavior is undefined.
format | A compose-style format string. Derived classes may define the number of argument references expected in the string; the default is one. If format is empty, a minimal default should be used. |
Implements Elemental::value_base.
|
virtual |
Returns a color representing the value.
Derived classes must implement this function, returning a color that corresponds to the defined value. A special color should be returned if has_value() is false
.
Implements Elemental::color_value_base.
