| virtual AnyData* AnyData::copy | ( | ) | const [virtual] |
Creates a copy of the custom data.
This method is called when the Any::copy() method is called to copy the data element. The default implementation of this method returns NULL so subclasses should override this method to create a new instance of the object and copy the actual data. Each subclass can define whether it performs a deep copy or a shallow copy.
- Returns:
- A pointer to a new data object containing a copy of this data. The default implementation returns NULL. If NULL is returned, the Any::copy() method will also return NULL.
Reimplemented in DataVariantAnyData.
| virtual bool AnyData::serialize | ( | SessionItemSerializer & | serializer | ) | const [virtual] |
Serializes the AnyData during save session.
This is equivalent to SessionItem::serialize() for AnyData objects.
- Parameters:
-
serializer The object to use to save the item as part of the current ` session.
- Returns:
- The default implementation simply returns
true.

| virtual bool AnyData::deserialize | ( | SessionItemDeserializer & | deserializer | ) | [virtual] |
Deserializes the AnyData during restore session.
This is equivalent to SessionItem::deserialize() for AnyData objects.
- Parameters:
-
deserializer The object to use to restore the item from a saved session.
- Returns:
- The default implementation simply returns
true.
