Check --- that a call to such an operator executes the body of the type's --- operation. --- --- TEST DESCRIPTION: --- A type may declare a primitive operator, and a subtype of that type --- may overload the operator. If a use type clause names the subtype, --- it is the primitive operator of the type (not the subtype) which --- is made directly visible, and the primitive operator may be called --- unambiguously. Such a call executes the body of the type's operation. --- --- In a package, declare a type for which a predefined operator is --- overridden. In another package, declare a subtype of the type in the --- previous package. Declare another version of the predefined operator --- for the subtype. --- --- The main program declares objects of both the type and the explicit --- subtype, and uses the "**" operator for both. In all cases, the --- operator declared for the 1st subtype should be the one executed, --- since it is the primitive operators of the *type* that are made --- visible; the operators which were declared for the explicit subtype --- are not primitive operators of the type, since they were declared in --- a separate package from the original type. --- --- --- CHANGE HISTORY: --- 06 Dec 94 SAIC ACVC 2.0 --- 23 Sep 99 RLB Added test case where operator made visible is --- not visible by selection (as in AI-00122). --- ---! - -package C840001_0 is --- Usage scenario: the predefined operators for a floating point type --- are overridden in order to take advantage of improved algorithms. - - type Precision_Float is new Float range -100.0 .. 100.0; - -- Implicit: function "**" (Left: Precision_Float; Right: Integer'Base) - -- return Precision_Float; - - function "**" (Left: Precision_Float; Right: Integer'Base) - return Precision_Float; - -- Overrides predefined operator. - - function "+" (Right: Precision_Float) - return Precision_Float; - -- Overrides predefined operator. - - -- ...
