Constructor & Destructor Documentation

virtual expression_list::~expression_list

(

)

[virtual]

The destructor.

expression_list::expression_list

(

)

The default constructor.

expression_list::expression_list

(

const expression::pointer &

arg

)

The constructor.

expression_list::expression_list

(

const expression_list &

)

The copy constructor.

Member Function Documentation

expression_list& expression_list::operator=

(

const expression_list &

)

The assignment operator.

void expression_list::push_front

(

const expression::pointer &

esp

)

The push_front method is used to add another expression to the beginning of the list.

This is an O(n) operation.

void expression_list::push_back

(

const expression::pointer &

esp

)

The push_back method is used to add another expression to the end of the list.

This is an O(1) operation.

void expression_list::push_back

(

const expression_list &

arg

)

The push_back method is used to push a whole list on the back of this list.

Parameters:

arg

This is to be appended.

size_t expression_list::size

(

)

const [inline]

The size method is used to obtain the number of elements in the list.

Definition at line 90 of file list.h.

References length.

Referenced by expression_function_call::get_child_count().

bool expression_list::empty

(

)

const [inline]

The empty method is used to determine whether or not the list is empty.

Definition at line 96 of file list.h.

References length.

Referenced by statement_writeln::has_args().

expression::pointer expression_list::get

(

size_t

n

)

const [inline]

The get method is used to obtain a specific member of the list.

Definition at line 101 of file list.h.

References item.

Referenced by expression_function_call::get_child(), and operator[]().

expression::pointer expression_list::operator[]

(

size_t

n

)

const [inline]

The subscript operator is used to obtain a specific member of the list.

Definition at line 107 of file list.h.

References get().

expression_list* expression_list::clone

(

)

const

The clone method is used to make a deep copy of this expression list. It calls the member expressions' clone methods.

expression::pointer expression_list::front

(

)

const [inline]

The front method is used to obtain the first item in the list.

Definition at line 119 of file list.h.

References item, and length.

expression::pointer expression_list::back

(

)

const [inline]

The back method is used to obtain the last item in the list.

Definition at line 129 of file list.h.

References item, and length.

expression::side_effect_t expression_list::has_side_effect

(

)

const

The has_side_effect method is used to determine if an expression has any effect. It is used by the parse to produce "statement with no effect" warnings.

expression::pointer expression_list::pop_front

(

)

The pop_front method is used to remove the first element from the list, and return it. If the list is empty, the NULL pointer is returned.

expression::pointer expression_list::pop_back

(

)

The pop_back method is used to remove the last element from the list, and return it. If the list is empty, the NULL pointer is returned.

void expression_list::clear

(

)

The clear method is used to discard all list contents.

location expression_list::get_location

(

)

const

The get_location method is used to obtain the location of the expression list.

size_t expression_list::length [private]

The length instance variable is used to remember how many elements of the item array have been used to date.

size_t expression_list::maximum [private]

The maximum instance variable is used to remember the allocation size of the item array.

Definition at line 178 of file list.h.

expression::pointer* expression_list::item [private]

The item instance variable is used to remember the address of the dynamically allocated array of expression pointers.
