[sv-bc] RE: [sv-ec] overloading an assignment operator

Hi Steven,

 

SV LRM 8.16 has these lines.

================

Overloading the assignment operator also serves to overload implicit
assignments or casting. Here these are

using the same functions as the unary +.

bind = function float fcopyi(int); // cast int to float

bind = function float fcopyr(real); // cast real to float

bind = function float fcopyr(shortreal); // cast shortreal to float

 

So it means LRM gives provision for overloading assignment.

 

Thank,

Subhamoy

The LRM lists the operators that can be overloaded, and it does not

include assignment.  There is other text that indicates that this

was not an oversight.  The LRM only allows overloading of operators

when applied to data types that would otherwise be illegal for them.

Assignment is legal for all data types.  The LRM also explicitly talks

about arithmetic operators, which does not include assignment.  So it

seems quite clear that an assignment operator cannot be overloaded.
