C# Class Lucene.Net.Index.MergePolicy.OneMerge

OneMerge provides the information necessary to perform an individual primitive merge operation, resulting in a single new segment. The merge spec includes the subset of segments to be merged as well as whether the new segment should use the compound file format.

Public Methods

Method	Description
CheckAborted ( Directory dir ) : void	Called periodically by IndexWriter while merging to see if the merge is aborted.
GetDocMap ( Lucene.Net.Index.MergeState mergeState ) : DocMap	Expert: If #getMergeReaders() reorders document IDs, this method must be overridden to return a mapping from the natural doc ID (the doc ID that would result from a natural merge) to the actual doc ID. this mapping is used to apply deletions that happened during the merge to the new segment.
OneMerge ( IList segments ) : System	Sole constructor.
SegString ( Directory dir ) : string	Returns a readable description of the current merge state.
TotalBytesSize ( ) : long	Returns the total size in bytes of this merge. Note that this does not indicate the size of the merged segment, but the input total size. this is only set once the merge is initialized by IndexWriter.
TotalNumDocs ( ) : int	Returns the total number of documents that are included with this merge. Note that this does not indicate the number of documents after the merge.

Private Methods

Method	Description
Abort ( ) : void	Mark this merge as aborted. If this is called before the merge is committed then the merge will not be committed.

GetDocMap() public method

Expert: If #getMergeReaders() reorders document IDs, this method must be overridden to return a mapping from the natural doc ID (the doc ID that would result from a natural merge) to the actual doc ID. this mapping is used to apply deletions that happened during the merge to the new segment.

TotalBytesSize() public method

Returns the total size in bytes of this merge. Note that this does not indicate the size of the merged segment, but the input total size. this is only set once the merge is initialized by IndexWriter.
