| Protected Member Functions inherited from AbstractPrivateData | |
| virtual DLLLOCAL | ~AbstractPrivateData () |
| as these objects are reference counted, the destructor should be called only when the reference count = 0 and not manually | |

base class for saving data using Qore's thread resource management system
Thread resources are resources that are tied to a particular thread. Qore provides the ability to call the object's "cleanup()" function if the resource is still allocated to the thread when the thread terminates. For example, the Datasource transaction lock is implemented as a thread resource. If the used does not commit or rollback an open transaction before the thread terminates, ManagedDatasource::cleanup() is run, which will throw an exception, rollback the transaction, and release the transaction lock. When a thread commits or rolls back a transaction, the thread resource is removed. Use the set_thread_resource() to set and remove_thread_resource() to remove thread resources.
