Value com.quadcap.sql.types.ValueType.binop (  int  op,
Value  l
)  throws ValueException [virtual]
 

Two-level virtual operator dispatch.

Each subtype implements the same basic template for this abstract function: 



 Value binop(int op, Value l) {
    return l.binop(op, this);
 }


 
 Then, type overloading allows for each type to implement all ops for which it can be the left hand side for all allowed types on the right hand side: Value binop(int op, ValueInteger l); Value binop(int op, ValueLong l); ...
