Detailed Description

Statically allocated core of a double linked list, pointers to next, previous.

This is the simplest list node, used as base class for other list nodes and as storage for static_double_list, that must be available for any statically constructed objects while still avoiding the 'static initialisation order fiasco'.

The idea is to design the object in such a way as to benefit from the standard BSS initialisation, in other words take nullptr as starting values.

Constructor & Destructor Documentation

◆ static_double_list_links()

os::utils::static_double_list_links::static_double_list_links ( )

Construct a list node (BSS initialised).

Definition at line 831 of file lists.h.

◆ ~static_double_list_links()

os::utils::static_double_list_links::~static_double_list_links ( )

Destruct the node.

Definition at line 836 of file lists.h.

Member Function Documentation

◆ next() [1/2]

void os::utils::static_double_list_links::next ( static_double_list_links n)

Definition at line 865 of file lists.h.

◆ next() [2/2]

static_double_list_links * os::utils::static_double_list_links::next ( void  ) const

Definition at line 853 of file lists.h.

◆ prev() [1/2]

void os::utils::static_double_list_links::prev ( static_double_list_links n)

Definition at line 871 of file lists.h.

◆ prev() [2/2]

static_double_list_links * os::utils::static_double_list_links::prev ( void  ) const

Definition at line 859 of file lists.h.

◆ unlink()

void os::utils::static_double_list_links::unlink ( void  )

Remove the node from the list.


Update the neighbours to point to each other, skipping the node.

For more robustness, to prevent unexpected accesses, the links in the removed node are nullified.

Definition at line 57 of file lists.cpp.

◆ unlinked()

bool os::utils::static_double_list_links::unlinked ( void  )

Check if the node is unlinked.

Return values
trueThe node is not linked.
falseThe node is linked to a list.

Definition at line 847 of file lists.h.
