Constructor & Destructor Documentation

Elemental::Block::Block ( const Value source,
Qualifier  qualifier = Q_NEUTRAL 
) throw ()

Constructs a new defined block.

Parameters:
source The initial definition.
qualifier The qualification of the initial value.

Elemental::Block::Block ( Qualifier  qualifier = Q_UNK  )  throw ()

Constructs a new undefined or default block.

Parameters:
qualifier The qualification of the initial value.


Member Function Documentation

virtual int Elemental::Block::compare ( const value_base other  )  const throw () [virtual]

Compares two qualified values.

Derived classes may override this function, first calling compare_base, and use a dynamic_cast to check other.

Parameters:
other The qualified value for comparison.
Returns:
-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.

virtual color Elemental::Block::get_color (  )  const throw () [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.

Returns:
A color structure.

Implements Elemental::color_value_base.

virtual ustring Elemental::Block::do_get_string ( const ustring &  format  )  const throw () [protected, virtual]

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.

Parameters:
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.
Returns:
A UTF-8 string containing the localized representation.

Implements Elemental::value_base.
