Detailed Description

Expression for arguments in a statement function.

Description

An ArgNumberExpr is the expression for arguments of a statement function. Arg number 1 is the first statement function argument, arg number 2 is the second, and so forth. These should never be seen in a scanned program since statement functions are in-lined as the program is being parsed.

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

Return a copy of myself.

References ArgNumberExpr().

int ArgNumberExpr::structures_OK ( ) const [virtual]

Return 1 if my structures are in a valid state.

Implements Expression.

References True.

virtual void ArgNumberExpr::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.

virtual void ArgNumberExpr::print_debug ( ostream & o,

Boolean debug

) const [virtual]

debug indicates whether it should contain extra fields

Implements Expression.

const ExprSignature & ArgNumberExpr::update_signature ( ) [virtual]
