A COSObject has changed its internal state. For any
COSObject this may be a change in containement (slot == COSObject.SLOT_CONTAINER).
For containers itself, this may be a change in the collection of
contained objects. For dictionaries, slot will be the
COSName of
the changed entry, for arrays slot will be the
Integer key. A
stream may indicate a change in its byte content using (slot ==
COSStream.SLOT_BYTES).
A slot value of null may indicate a "changed all" event.
For example you can expect for a clear operation on an
array only a single "changed all" event.
Parameters: object - The object that has changed Parameters: slot - The slot in the object that has changed (or null forunspecified change). Parameters: oldValue - The old value of the slot if known. Parameters: newValue - The new value of the slot if known. |
