Description

A CommaExpr represents a comma-separated list of expressions. CommaExprs are typically used for representing the argument lists of array references or function calls.

Constructor & Destructor Documentation

CommaExpr::CommaExpr ( ) [inline]

Constructor for a CommaExpr with no args.
< nothing to do
Definition at line 70 of file CommaExpr.h.
References COMMA_OP, make_type(), and VOID_TYPE.

CommaExpr::CommaExpr ( Expression * exp1,

Expression * exp2 = 0,

Expression * exp3 = 0,

Expression * exp4 = 0,

Expression * exp5 = 0

) [inline]

Constructor for a CommaExpr with up to five args.

CommaExpr::CommaExpr ( List< Expression > * list ) [inline]

Creates a new CommaExpr object with the expressions in 'list' as its arguments.
'list' is deleted automatically, so the user must NOT delete 'list' after the call to this constructor.

CommaExpr::CommaExpr ( const CommaExpr & e ) [inline]

Copy constructor.
< nothing to do
Definition at line 96 of file CommaExpr.h.

CommaExpr::~CommaExpr ( ) [virtual]

Virtual destructor.

Member Function Documentation

CommaExpr & CommaExpr::operator= ( const CommaExpr & ) [virtual]

Copy assignment.

Definition at line 3863 of file Expression.cc.

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

Return a copy of myself.

int CommaExpr::structures_OK ( ) const [virtual]

Return 1 if my structures are in a valid state.

Reimplemented from NonBinaryExpr.
Definition at line 3871 of file Expression.cc.

virtual void CommaExpr::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.
Reimplemented from NonBinaryExpr.

virtual void CommaExpr::print_debug ( ostream & o,

Boolean debug

) const [virtual]

See Expression.h.

Reimplemented from NonBinaryExpr.

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

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

Reimplemented from NonBinaryExpr.
