LinkedElements< N, ALO > Class Template Reference

#include "lib/linked-elements.hpp"

Description

template<class N, class ALO = linked_elements::OwningHeapAllocated>
class lib::LinkedElements< N, ALO >

Intrusive single linked list, possibly taking ownership of node elements.

Additional elements can be pushed (prepended) to the list; element access is per index number (slow) or through an Lumiera Forward Iterator traversing the linked list. There is no support for changing the list contents aside of discarding any element in the list.

The allocation and ownership related behaviour is controlled by a policy class provided as template parameter. When this policy supports creation of new elements, these might be created and prepended in one step.

Constructor & Destructor Documentation

◆ LinkedElements() [1/2]

LinkedElements ( typename ALO::CustomAllocator  allo)
inlineexplicit
Parameters
allocustom allocator or memory manager to be used by the policy for creating and discarding of node elements

Definition at line 253 of file linked-elements.hpp.

◆ LinkedElements() [2/2]

LinkedElements ( IT &&  elements)
inline

creating a LinkedElements list in RAII-style:

Parameters
elementsiterator to provide all the elements to be pushed into this newly created collection
Note
any exception while populating the container causes already created elements to be destroyed

Definition at line 265 of file linked-elements.hpp.

Member Function Documentation

◆ clear()

void clear ( )
inline
Note
EX_FREE

Definition at line 283 of file linked-elements.hpp.

◆ pushAll()

void pushAll ( IT  elements)
inline

convenience shortcut to add all the elements yielded by the given Lumiera Forward Iterator

Note
EX_SANE

Definition at line 303 of file linked-elements.hpp.

◆ push()

TY& push ( TY &  elm)
inline

accept the given element and prepend it to the list of elements; depending on the allocation policy, this might imply taking ownership

Note
EX_STRONG

Definition at line 318 of file linked-elements.hpp.

◆ reverse()

LinkedElements& reverse ( )
inline

Mutate the complete list to change the order of elements.

Remarks
since pushing prepends, elements are initially in reverse order
Warning
this operation invalidates iterators and has O(n) cost; ownership and elements themselves are not affected.

Definition at line 350 of file linked-elements.hpp.

◆ top()

N& top ( ) const
inline
Warning
unchecked

Definition at line 390 of file linked-elements.hpp.

◆ size()

size_t size ( ) const
inline
Warning
traverses to count the elements
