DUMMY FUNCTIONS.

void IntConstExpr::value ( int ) [virtual]

Access the integer value of the expression.

Expression * IntConstExpr::clone ( ) const [virtual]

Return a copy of myself.

Implements Expression.
Definition at line 5168 of file Expression.cc.
References IntConstExpr().

virtual void IntConstExpr::print_debug ( ostream & o,

Boolean debug

) const [virtual]

debug indicates whether it should contain extra fields

Implements Expression.

int IntConstExpr::structures_OK ( ) const [virtual]

Return 1 if my structures are in a valid state.

Implements Expression.
Definition at line 5183 of file Expression.cc.
References True.

virtual void IntConstExpr::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.
Implements Expression.

int IntConstExpr::exchange_expr ( VDL & vdl ) [virtual]

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