intrusive_list


An intrusive list.
No STL equivalent.

etl::intrusive_list<typename TValue, typename TLink = etl::bidirectional_link<0> >

TValue is the type that contains the actual values. It is derived from Tlink. Tlink is the link type for this list.
See Intrusive links.

Member types


typedef TLink             link_type;
typedef TValue            value_type;
typedef value_type*       pointer;
typedef const value_type* const_pointer;
typedef value_type&       reference;
typedef const value_type& const_reference;
typedef size_t            size_type;

____________________________________________________________________________________________________

Constructor


etl::list<typename TValue, typename TLink>();

template <typename TIterator>
etl::list<typename TValue, typename TLink>(TIterator begin, TIterator end);

____________________________________________________________________________________________________

Element access


TValue& front()
const T& front() const

Returns a reference or const reference to the first element.
____________________________________________________________________________________________________

TValue& back()
const T& back() const

Returns a reference or const reference to the last element.

____________________________________________________________________________________________________

Iterators


iterator begin()
const_iterator begin() const
const_iterator cbegin() const

Returns an iterator to the beginning of the list.
____________________________________________________________________________________________________

iterator end()
const_iterator end() const
const_iterator cend() const

Returns an iterator to the end of the list.
____________________________________________________________________________________________________

iterator rbegin()
const_iterator rbegin() const
const_iterator crbegin() const

Returns a reverse iterator to the beginning of the list.
____________________________________________________________________________________________________

iterator rend()
const_iterator rend() const
const_iterator crend() const

Returns a reverse iterator to the end of the list.

____________________________________________________________________________________________________

Capacity


bool empty() const

Returns true if the size of the list is zero, otherwise false.
____________________________________________________________________________________________________

size_t size() const

Returns the size of the list.

____________________________________________________________________________________________________

Modifiers


template <typename TIterator>
void assign(TIterator begin, TIterator end);

Fills the list with the values.
____________________________________________________________________________________________________

void push_front(value_type& value);

Pushes a value to the front of the list.
____________________________________________________________________________________________________

void push_back(value_type& value);

Pushes a value to the back of the list.
____________________________________________________________________________________________________

void pop_front();

Pop a value from the front of the list.
Emits an etl::intrusiveList _empty if the list is empty. If asserts or exceptions are disabled then undefined
behaviour occurs.
____________________________________________________________________________________________________

void pop_back();

Pop a value from the back of the list.
Emits an etl::intrusiveList _empty if the list is empty. If asserts or exceptions are disabled then undefined
behaviour occurs.
____________________________________________________________________________________________________

template <typename TIterator>
void insert(iterator position, TIterator begin, TIterator end);

iterator insert(iterator position, value_type& value);

Inserts values in to the list.
position is not checked for validity.
____________________________________________________________________________________________________

template <typename TIterator>
iterator erase(TIterator begin, TIterator end);

iterator erase(iterator position);

Erases values in the list.
Iterators are not checked for validity.
____________________________________________________________________________________________________

void clear();

Clears the list to a size of zero. No elements are destructed.
____________________________________________________________________________________________________

void splice(iterator position, list_type& list);
void splice(iterator position, list_type& list, iterator isource);
void splice(iterator position, list_type& list, iterator begin_, iterator end_);

Splices elements from a list into this list.
Iterators are not checked for validity.
____________________________________________________________________________________________________

void merge(list_type& list);

Merges the sorted elements of 'list' into this list. Merges are stable.
If a debug compile and asserts or exceptions are enabled than an etl::intrusive_list_unsorted is emitted if either
list is unsorted, otherwise undefined behaviour occurs.
____________________________________________________________________________________________________

tempate <typename TCompare>
void merge(list_type& list, Tcompare compare);

Merges the sorted elements of list into this list. Comparison functor is supplied in compare. Merges are stable.
If a debug compile and asserts or exceptions are enabled than an etl::intrusive_list_unsorted is emitted if either
list is unsorted, otherwise undefined behaviour occurs.

____________________________________________________________________________________________________

Operations


void remove(const T& value);

Removes from the container all the elements that compare equal to value.
____________________________________________________________________________________________________

template <typename TPredicate>
void remove_if(TPredicate predicate);

Removes from the container all the elements that satisfy predicate.
____________________________________________________________________________________________________

void unique();

template <typename TPredicate>
void unique(TPredicate predicate);

The first version removes all but the first element from every group of consecutive elements.
The second removes all but the first element from every group of consecutive elements that satisfy the binary
predicate.
____________________________________________________________________________________________________

void sort();

template <typename TCompare>
void sort(TCompare compare);

The first version sorts using the < operator.
The second uses the supplied compare function.
____________________________________________________________________________________________________

void reverse();

Reverses the order of the list.

____________________________________________________________________________________________________

Non-member functions


==  true if the contents of the lists are equal, otherwise false.
!=  true if the contents of the lists are not equal, otherwise false.
<   true if the contents of the lhs are lexicographically less than the contents of the rhs,  otherwise false.
<=  true if the contents of the lhs are lexicographically less than or equal to the contents of the rhs, otherwise false.
>   true if the contents of the lhs are lexicographically greater than the contents of the rhs,  otherwise false.
>=  true if the contents of the lhs are lexicographically greater than or equal to the contents of the rhs, otherwise false.
