Открытые методы

Метод Описание
Dispose ( ) : void

Disposes the current object.
IndexStorerBase ( IInMemoryIndex index ) : System

Initializes a new instance of the IndexStorerBase class.
LoadIndex ( ) : void

Loads the index from the data store the first time.

Защищенные методы

Метод Описание
DeleteData ( DumpedChange data, object state ) : void

Deletes data from the data storage.
Find ( DumpedWord word, IEnumerable list ) : bool

Determines whether a DumpedWord is contained in a list.
Find ( DumpedWordMapping mapping, IEnumerable list ) : bool

Determines whether a DumpedWordMapping is contained in a list.
IndexChangedHandler ( object sender, IndexChangedEventArgs e ) : void

Handles the IInMemoryIndex.IndexChanged events.
InitDataStore ( object state ) : void

Initializes the data storage.
LoadIndexInternal ( DumpedDocument &documents, DumpedWord &words, DumpedWordMapping &mappings ) : void

Loads the index from the data store the first time.
SaveData ( DumpedChange data, object state ) : IndexStorerResult

Stores new data into the data storage.

When saving a new document, the document ID in data.Mappings must be replaced with the currect document ID, generated by the concrete implementation of this method. data.Words should have IDs numbered from uint.MaxValue downwards. The method re-numbers the words appropriately.
