Detailed Description

An expression representing an iterator.

Description

An EqualExpr is the starting point expression in an I/O iterator. For example, in the statement "write *,(a(i), i=1,30)" the EqualExpr represents the "i=1,30" part. It has two arguments, the index (i) and the iteration space (1,30).

USE: index_id must be an IDExpr iteration_space must be a CommaExpr

const Expression & EqualExpr::index_id ( ) const [virtual]

Reimplemented from Expression.
Definition at line 4291 of file Expression.cc.
References BinaryExpr::_left_guarded().

void EqualExpr::index_id ( Expression * ) [virtual]

Return the index variable of the expression.
The index_id must always be an IDExpr.

References BinaryExpr::_right_guarded().

void EqualExpr::iteration_space ( Expression * ) [virtual]

Return a comma separated list containing the lower and upper bounds of the iteration space and a possible stride.
The iteration_space must always be a CommaExpr.

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

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

Return a copy of myself.

Reimplemented from BinaryExpr.
Definition at line 4269 of file Expression.cc.
References EqualExpr().

int EqualExpr::structures_OK ( ) const [virtual]

Return 1 if my structures are in a valid state.

Reimplemented from BinaryExpr.
Definition at line 4323 of file Expression.cc.
References True.

virtual void EqualExpr::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 EqualExpr::print_debug ( ostream & o,

Boolean debug

) const [virtual]

See Expression.h.

Reimplemented from BinaryExpr.

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

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

Reimplemented from BinaryExpr.
Definition at line 4330 of file Expression.cc.
References Expression::exchange_expr(), BinRep::find_ref(), Set< T >::ins(), List< T >::ins_last(), and BinRep::to_tuple().
