Открытые методы

Метод Описание
AddOccurrence ( IDocument document, ushort firstCharIndex, ushort wordIndex, WordLocation location ) : void

Stores an occurrence.

Adding an occurrence is O(n), where n is the number of occurrences of the word already stored for the same document. If there were no occurrences previously stored, the operation is O(1).

BulkAddOccurrences ( IDocument document, SortedBasicWordInfoSet positions ) : void

Adds a bulk of occurrences of the word in a document, removing all the old positions, if any.

If positions is empty, the effect of the invocation of the method is equal to that of RemoveOccurrences with the same document. Bulk-adding the occurrences is O(1).

RemoveOccurrences ( IDocument document ) : List

Removes all the occurrences for a document.

Removing the occurrences for the document is O(1).

ToString ( ) : string

Gets a string representation of the current instance.
Word ( uint id, string text ) : System

Initializes a new instance of the Word class.
Word ( uint id, string text, OccurrenceDictionary occurrences ) : System

Initializes a new instance of the Word class.
