Description

An ArrayRefExpr is an array reference. It consists of an array name and a subscripting expression.

USE: array is an IDExpr subscript is a CommaExpr

void ArrayRefExpr::array (  Expression *   )  [virtual]
 

Access the variable name of the array reference.

This expression should always be an IDExpr.

Reimplemented from Expression.

Definition at line 61 of file ArrayRefExpr.h.

References BinaryExpr::_right_guarded().

void ArrayRefExpr::subscript (  Expression *   )  [virtual]
 

Access the subscript expression of the array reference.

This expression should always be a CommaExpr.

Reimplemented from Expression.

Definition at line 3425 of file Expression.cc.

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

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

Return a copy of myself.

Reimplemented from BinaryExpr.

Definition at line 3400 of file Expression.cc.

References ArrayRefExpr().

int ArrayRefExpr::structures_OK (   )  const [virtual]
 

Return 1 if my structures are in a valid state.

Reimplemented from BinaryExpr.

Definition at line 3433 of file Expression.cc.

References True.

virtual void ArrayRefExpr::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.

Boolean  debug
)  const [virtual]
 

See Expression.h.

Reimplemented from BinaryExpr.

const Symbol * ArrayRefExpr::base_variable_ref (   )  const [virtual]
 

base_symbol If I am an IDExpr or an ArrayRefExpr, return the name of myself, otherwise return NULL.

Reimplemented from Expression.

Definition at line 11619 of file Expression.cc.

References array(), ID_OP, Expression::op(), and Expression::symbol().
