Fields

group_id: u32

A non-negative integer assigned to the particular grouping that shall not be equal to any group_id value of any other EntityToGroupBox, any item_ID value of the hierarchy level (file, movie or track) that contains the GroupsListBox, or any track_ID value (when the GroupsListBox is contained in the file level).

num_entities_in_group: u32

Specifies the number of entity_id values mapped to this entity group.

entity_id: Vec<u32>

Resolved to an item, when an item with item_ID equal to entity_id is present in the hierarchy level (file, movie or track) that contains the GroupsListBox, or to a track, when a track with track_ID equal to entity_id is present and the GroupsListBox is contained in the file level.
