Detailed Description

Class that implements the behavior of a user on the social media.

The class provides the descision making for when agents read and create messages. When default_media_user::generate_post_events is called during Social_Media_with_followers::think to create post events, they events are created independently with a random piece of known knowledge. When an event is parsed in Social_Media_with_followers::communicate, default_media_user::parse is immediately called which checks for a knowledge index in the read event. If the peice of knowledge in the event is already known, media_user::(reply, quote, repost) is then called. In these calls, the class decides whether to respond to the submitted event. After any event is created, enrich_event is called which allows other models to intercept the created event.

This provides a loose guideline for how to create different types of users that respond to events in different ways. Examples might be, createing a graph that changes how likely an agent would respond based on the peice of knowledge, modifying what other events an agent parses when reading an event, or additional actions that should be taken when parsing an event. To create custom event generation, use Social_Media_no_followers::create_post, Social_Media_no_followers::create_reply, etc. Always call default_media_user::enrich_event on all event created after adding any custom information.

Constructor & Destructor Documentation

default_media_user()

Social_Media_no_followers::default_media_user::default_media_user	(	Social_Media_no_followers *	reddit,
		const Node &	node
	)

Constructor that takes the media pointer this user is apart of and the iterator containing all the required node attributes.

Some required node attribute names depend on Social_Media_with_followers::media_name. Thus the following attributes are required:

• media_name + " post density"
• media_name + " reply probability"
• media_name + " repost probability"
• media_name + " quote probability"
• media_name + " reading density"

Here is the call graph for this function:

Member Function Documentation

enrich_event()

void Social_Media_no_followers::default_media_user::enrich_event ( media_event *  _event )

virtual

Enirches the event with information.

By default this is called after every event is created by this class. The last operation in this function is Social_Media_no_followers::finalize_event. Any functions that override this function should call this function after performing all other operations.

Reimplemented in SM_wf_emotions::default_media_user, and Social_Media_with_followers::default_media_user.

Here is the caller graph for this function:

generate_post_events()

void Social_Media_no_followers::default_media_user::generate_post_events ( void  )

virtual

The user adds a number of post events based on default_media_user::pdp.

Implements Social_Media_no_followers::media_user.

Here is the call graph for this function:

get_knowledge_selection()

unsigned int Social_Media_no_followers::default_media_user::get_knowledge_selection ( void  )

virtual

Called during media_user::generate_post_events to choose which piece of knowledge to add to a media_event.

Reimplemented in SM_wf_emotions::default_media_user.

Here is the call graph for this function:

get_read_count()

unsigned int Social_Media_no_followers::default_media_user::get_read_count ( void  )

virtual

The user reads a number of events based on default_media_user::pdread.

Implements Social_Media_no_followers::media_user.

Here is the call graph for this function:

parse()

void Social_Media_no_followers::default_media_user::parse ( media_event *  _event )

virtual

The parsed event is checked to ensure it contains knowledge

Implements Social_Media_no_followers::media_user.

Here is the call graph for this function:

Here is the caller graph for this function:

quote()

void Social_Media_no_followers::default_media_user::quote ( media_event *  _event )

virtual

With proabability default_media_user::pqu creates a quote to the event.

Implements Social_Media_no_followers::media_user.

Here is the call graph for this function:

read()

std::set< Social_Media_no_followers::media_event * > Social_Media_no_followers::default_media_user::read ( media_event *  read_event )

virtual

Collects all events an agent will parse when reading an event.

Implements Social_Media_no_followers::media_user.

reply()

void Social_Media_no_followers::default_media_user::reply ( media_event *  _event )

virtual

With proabability default_media_user::pr creates a reply to the event.

Implements Social_Media_no_followers::media_user.

Here is the call graph for this function:

repost()

void Social_Media_no_followers::default_media_user::repost ( media_event *  _event )

virtual

With proabability default_media_user::prp creates a quote to the event.

Implements Social_Media_no_followers::media_user.
