C# (CSharp) Lucene.Net.Facet.Taxonomy.Directory DirectoryTaxonomyWriter.Rollbackの例

Rollback() public method

Rollback changes to the taxonomy writer and closes the instance. Following this method the instance becomes unusable (calling any of its API methods will yield an AlreadyClosedException).

public Rollback ( ) : void
return	void
