*
SwTextMeta
the text hint
*
SwFormatMeta
the pool item
*
sw::Meta
the metadatable entity itself
*
SwXMeta
the UNO wrapper object
*
* * The text hint contains the pool item (as usual) and has a pointer to the * text node at which it is attached. * The pool item has a shared pointer to the metadatable entity, and a reverse * pointer to the text attribute at which it is attached. * The pool item is non-poolable; it may only be attached to one text * attribute. * Of all the pool items that refer to a metadatable entity, only one may be * in the document content at any time. Others may be in the undo array, or in * undo objects. * The metadatable entity has a reverse pointer to the pool item that is * currently in the document. It also registers as a client at the text node * at which it is attached via this pool item and its text attribute. * The UNO wrapper object registers as a client at the metadatable entity. * * Copying the metadatable entity proceeds in the following way: *
    *
  1. The pool item is cloned (because it is non-poolable); the clone * points to the same metadatable entity, but the metadatable entity's * reverse pointer is unchanged.
  2. *
  3. The DoCopy() method is called at the new pool item: * it will clone the metadatable entity (using RegisterAsCopyOf). * This is necessary, because first, a metadatable entity may * only be inserted once into a document, and second, the copy may be * inserted into a different document than the source document!
  4. *
  5. A new text hint is created, taking over the new pool item.
  6. *
  7. The text hint is inserted into the hints array of some text node.
