Detailed Description
The rpt_expr_constant class is used to represent expression nodes which have a constant value.Definition at line 29 of file constant.h.
Constructor & Destructor Documentation
| rpt_expr_constant::~rpt_expr_constant | ( | ) |
The destructor.
| rpt_expr_constant::rpt_expr_constant | ( | const rpt_value::pointer & | value | ) | [private] |
The constructor. It is private because all users of the API are required to create new instances via the create class method.
- Parameters:
-
value The value of this constant expression.
| rpt_expr_constant::rpt_expr_constant | ( | ) | [private] |
The default constructor. Do not use.
| rpt_expr_constant::rpt_expr_constant | ( | const rpt_expr_constant & | ) | [private] |
The copy constructor. Do not use.
Member Function Documentation
| static pointer rpt_expr_constant::create | ( | const rpt_value::pointer & | value | ) | [static] |
The create class method is used to create new dynamically allocated instances.
- Parameters:
-
value The value of this constant expression.
| bool rpt_expr_constant::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.
| const char* rpt_expr_constant::name | ( | ) | const [protected] |
| rpt_value::pointer rpt_expr_constant::evaluate | ( | ) | const [protected, virtual] |
The evaluate method may be used to calculate the value of the expression syntax tree.
Implements rpt_expr.
| rpt_expr_constant& rpt_expr_constant::operator= | ( | const rpt_expr_constant & | ) | [private] |
The assignment operator. Do not use.
