Constructor & Destructor Documentation

virtual rpt_expr_lookup::~rpt_expr_lookup

(

)

[virtual]

The destructor.

rpt_expr_lookup::rpt_expr_lookup	(	const rpt_expr::pointer &	lhs,
		const rpt_expr::pointer &	rhs
	)		[private]

The constructor. It is private on purpose, use the "create" class method instead.

Parameters:

lhs	The left hand expression, the array to index
rhs	The right hand expression, the array index

rpt_expr_lookup::rpt_expr_lookup

(

)

[private]

The default constructor. Do not use.

rpt_expr_lookup::rpt_expr_lookup

(

const rpt_expr_lookup &

)

[private]

The copy constructor. Do not use.

Member Function Documentation

static rpt_expr::pointer rpt_expr_lookup::create	(	const rpt_expr::pointer &	lhs,
		const rpt_expr::pointer &	rhs
	)		[static]

The create class method is used to create new dynamically allocated instances of this class.

Parameters:

lhs	The left hand expression, the array to index
rhs	The right hand expression, the array index

static rpt_expr::pointer rpt_expr_lookup::create	(	const rpt_expr::pointer &	lhs,
		const nstring &	rhs
	)		[static]

The create class method is used to create new dynamically allocated instances of this class.

Parameters:

lhs	The left hand expression, the structure to index
rhs	The right hand expression, the member name

rpt_value::pointer rpt_expr_lookup::evaluate

(

)

const [protected, virtual]

The evaluate method may be used to calculate the value of the expression syntax tree.

Implements rpt_expr.

bool rpt_expr_lookup::lvalue

(

)

const [protected, virtual]

The lvalue method may be used to determine whether or not this expression node is an L-value (something which may appear on the left hand side of an assigment, a variable).

The default implementation, which is true for the vast majority of expression nodes, returns false.

Reimplemented from rpt_expr.

rpt_expr_lookup& rpt_expr_lookup::operator=

(

const rpt_expr_lookup &

)

[private]

The assignment operator. Do not use.
