virtual void ReturnStarExpr::convert (  BinRep &  exprSet,
Symtab &  symtab
)  [virtual]
 

Read in the values of my fields and my subexpressions from the given BinRep object.

Convert(BinRep) expects the BinRep to be referencing an expression set of the same type as the expression. On return, all data from the expression set has been inserted into the appropriate fields in the expression object. NOTE that this converts the expression to an intermediate form which may contain TableExpr objects.

Boolean  debug

Create a node in the "expression" member and return the index.
