The BlackBoardProxy class is used to subscribe to a blackboard device.
A blackboard is a data-store which sends updates when an entry is changed. It also returns the current value of an entry when a proxy first subcribes to that entries key. If an entry does not exist, the default value of that entry is returned.
| void PlayerCc::BlackBoardProxy::SetEventHandler | ( | void(*)(playerc_blackboard_t *, player_blackboard_entry_t) | on_blackboard_event | ) |
Set the function pointer which will be called when an entry is updated.
| void PlayerCc::BlackBoardProxy::SubscribeToGroup | ( | const char * | key | ) |
Subscribe to a group.
The event handler must be set to retrieve the current group entries.
| player_blackboard_entry_t* PlayerCc::BlackBoardProxy::SubscribeToKey | ( | const char * | key, |
| const char * | group = "" |
||
| ) |
Subscribe to a key.
If the key does not exist the default value is returned. The user must free the entry.
| void PlayerCc::BlackBoardProxy::UnsubscribeFromGroup | ( | const char * | group | ) |
Stop receiving updates about this group.
| void PlayerCc::BlackBoardProxy::UnsubscribeFromKey | ( | const char * | key, |
| const char * | group = "" |
||
| ) |
Stop receiving updates about this key.
