| virtual CkptObjectKey* CkptObject::getKey | ( | ) | [inline, virtual] |
Return the key used to store/retrieve this object.
This method can be overriden if the implementor wishes to calculate the key on demand instead of holding a key within the object. In this case, the setKey() methods will hold little meaning, although the base framework will still call them when a get() is executed. Overriding this may also have ramifications on memory management policies.

References _key.
Referenced by CkptContainer::persist(), and CkptContainer::remove().
| virtual void CkptObject::setKey | ( | CkptObjectKey * | key | ) | [inline, virtual] |
Set the key used to retrieve this object from its container.
The CkptObject takes ownership of the key passed in and will handle its deallocation appropriately.

References _key.
Referenced by setKey().
| virtual void CkptObject::setKey | ( | CkptObjectKey const & | key | ) | [inline, virtual] |
Set the key used to retrieve this object from its container.
The CkptObject creates a heap-based copy of the key and takes ownership of it.

References setKey().
| virtual void CkptObject::setKey | ( | std::string | s | ) | [inline, virtual] |
Set the key used to retrieve this object from its container.
The string is used to create a heap-based key, owned by the object.

References setKey().
| CkptRC CkptObject::commit | ( | ) |
Save any changes made to a managed object.
Commit the data changes in the object by flushing the data into the CKPT service. This will propigate to all nodes in the cluster that have this checkpoint (aka CkptContainer) open. A simple CkptObject example
