Detailed Description

A data structure to represent a tweet, facebook post, or any other social media event.

Events are linked into a tree with the root_event as the base of an event tree. Child events are contained in media_event::(replies, quotes, reposts). The non-default non-post constructors automatically link themselves to the their parent events. When an event is added to a tree using a non-default constructor, all other events in that tree have their media_event::last_used updated to be equal to the added event's media_event::time_stamp.

Constructor & Destructor Documentation

◆ ~media_event()

Social_Media_no_followers::media_event::~media_event ( )

Performs no actions unless DEBUG is enabled in which various assertions are checked.

media_event::last_used is checked between this event, parent_event, root_event, and all replies, quotes, and reposts. An assertion is raised if any event in a tree isn't synced. Next, the event removes itself from the parent event's replies, quotes, or reposts depending on media_event::type. An assertion is raised if it can not find itself in the corresponding data structure. Finally, the event sets all child event's media_event::parent_event their this pointer. An assertion is raised if this event is not the child event's parent_event. These assertions yield the relevant pointers as a string for debugging purposes and ensure that the event tree was properly synced.

◆ media_event() [1/3]

Social_Media_no_followers::media_event::media_event ( )

noexcept

Creates a blank event.

◆ media_event() [2/3]

Social_Media_no_followers::media_event::media_event ( media_event && temp )

noexcept

◆ media_event() [3/3]

Social_Media_no_followers::media_event::media_event ( const media_event & temp )

inline

Member Function Documentation

◆ check_consistency()

void Social_Media_no_followers::media_event::check_consistency ( void ) const

Checks whether the event is properly linked in the event tree.

Checks to make sure:

Posts have itself as its root event and parent event.
Replies, reposts, and quotes are listed in the corresponding data structure in the parent_event.
Replies, reposts, and quotes of this event have this as its parent event.
The root_event->last_used is equal to this->last_used.

If any of these conditions are not met of the event, an assertion is raised.

◆ operator==()

bool Social_Media_no_followers::media_event::operator== ( const media_event & a ) const

inline

Indicates whether this post has been removed/banned.

◆ operator>=()

bool Social_Media_no_followers::media_event::operator>= ( const media_event & a ) const

inline

summary>

◆ update_last_used()

void Social_Media_no_followers::media_event::update_last_used ( float time )

Updates this event's last_updated variable with the submitted time.

When this event is updated, this function is also called on all this event's child events.
