Full Version: Temporary meta data
Can I add a temporary custom meta field that will be kept only in memory? Or there are another methods to identify a playlist item that may be moved to another position or playlist later?

~ Files will not be altered; meta info will only be stored in the playlist (& database, if enabled). It will remain until you refresh / reload the file.

Thank you for your reply, but I don't want to block tags writing at all, I just want to identify the playlist item by any way...
I.e. (pseudocode):
CODE
class A : public menu_item_v2
{
virtual void perform_command(...){
data.get_item(0)->handle_temp_meta_put("my_meta_field", 1);
}
};
class B : public play_callback
{
virtual void on_playback_new_track(metadb_handle * track){
if(track->handle_temp_meta_get("my_meta_field")){
// do something
track->handle_temp_meta_remove("my_meta_field");
}
}
};
No, that is not possible. You would have to maintain a mapping from handles to temporary data yourself.
Thank you.
