| An interface for use by a message handler to allow |

| <p/> |
| A handler can have message-specific data that |
| needs to be associated the message being processed. |
| The handler can keep this message-specific data |
| in the Messagecontext object by adding the |
| data to the user data table via the |
| MessageContext method. When the MessageContext |
| object is saved (for example, to persistent storage), |
| and restored, this interface <B>SelfManagedDataManager</B> |
| provides a way for the handler to save and restore |
| the handler's message-specific data. |

| Implementors are expected to iterate through the data objects they wish |

| the data object is to be restored. |

| in the MessageContext object's SelfManagedData list and may include |
| additional information such as the implementor's fields. |
| Note that data stored by the implementor in the MessageContext object's SelfManagedData |
| list is retrievable by calling the MessageContext.getSelfManagedData() method |
| for EACH key/value pair. |
