Detailed Description

HistoryManager base implementation providing a simplified synchronous API.

This class simplifies the HistoryManager interface implementation by changing the interface to a single node based synchronous API and by providing a default implementation for most of the function, either returning an error BadHistoryOperationUnsupported or by providing an implementation like for read processed. The only required method to implement in the derived class is the readRawModified method. Other methods can be implemented if the functionality should be provided by the server.
