Description

A DoExpr is the loop-like structure in an I/O statement with an index and an iterator-expression: "( A(I), I=1,100,3)".

USE: iolist must be a CommaExpr iterator must be an EqualExpr

void DoExpr::iolist (  Expression *   )  [virtual]
 

Return a list of array references accessed by this expression.

The iolist must always be a CommaExpr.

References BinaryExpr::_right_guarded().

void DoExpr::iterator (  Expression *   )  [virtual]
 

Return the iterator of the expression.

The iterator must be an EqualExpr.

Reimplemented from Expression.

Definition at line 4138 of file Expression.cc.

References BinaryExpr::_right(), e, EQUAL_OP, and Expression::op().

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

Return a copy of myself.

Reimplemented from BinaryExpr.

Definition at line 4112 of file Expression.cc.

References DoExpr().

int DoExpr::structures_OK (   )  const [virtual]
 

Return 1 if my structures are in a valid state.

Reimplemented from BinaryExpr.

Definition at line 4158 of file Expression.cc.

References True.

virtual void DoExpr::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 BinaryExpr.

virtual void DoExpr::print_debug (  ostream &  o,
Boolean  debug
)  const [virtual]
 

See Expression.h.

Reimplemented from BinaryExpr.

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

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

Reimplemented from BinaryExpr.

Definition at line 4165 of file Expression.cc.

References Expression::exchange_expr(), BinRep::find_ref(), Set< T >::ins(), List< T >::ins_last(), and BinRep::to_tuple().
