Collaboration diagram for MetaData:

Detailed Description

MetaData container which can contain any number of any type of different Metadata-like objects.

By default none of the memory-heavy structures are created - they are stored as smart pointers.

This class also submits events when file names, hashests and so on are added to it. Refer to MDEvt documentation on event types submitted from this class, and EventTable documentation on how to handle events.

The objects of this class are owned by MetaDb and the destructor has been protected. As such, you cannot create MetaData objects on stack, and if you create them on heap, you MUST submit them to MetaDb because you are not able to delete them yourself.

Destructor is exposed to allow more generic usage of the object.

While the main purpose of this object was to remain hidden inside MetaDb and owned only by MetaDb, practice has shown this object is useful outside the MetaDb context also, and thus the destructor has been exposed. This does open a possibility of abuse though by objects using MetaData pointers given out by MetaDb.
