- + "IT Mill Toolkit data model provides interface for implementing "
- + "buffering in data components. The basic idea is that a component "
- + "reading their state from data source can implement "
- + "Buffered-interface, for storing the value internally. "
- + "Buffering provides transactional access "
- + "for setting data: data can be put to a component's buffer and "
- + "afterwards committed to or discarded by re-reding it from the data source. "
- + "The buffering can be used for creating interactive interfaces "
- + "as well as caching the data for performance reasons."
- + "<br /><br />Buffered interface contains methods for committing and discarding "
- + "changes to an object and support for controlling buffering mode "
- + "with read-through and write-through modes. "
- + "Read-through mode means that the value read from the buffered "
- + "object is constantly up to date with the data source. "
- + "Respectively the write-through mode means that all changes to the object are "
- + "immediately updated to the data source.";
