Syntax

public class MockRandomMergePolicy : MergePolicy, IDisposable

Constructors

MockRandomMergePolicy(Random)

Lucene.Net.Index.MergePolicy that makes random decisions for testing.

Declaration

public MockRandomMergePolicy(Random random)

Parameters

Type	Name	Description
Random	random

Methods

Dispose(bool)

Release all resources for the policy.

Declaration

protected override void Dispose(bool disposing)

Parameters

Type	Name	Description
bool	disposing

Overrides

MergePolicy.Dispose(bool)

FindForcedDeletesMerges(SegmentInfos)

Determine what set of merge operations is necessary in order to expunge all deletes from the index.

Declaration

public override MergePolicy.MergeSpecification FindForcedDeletesMerges(SegmentInfos segmentInfos)

Parameters

Type	Name	Description
SegmentInfos	segmentInfos	the total set of segments in the index

Returns

Type	Description
MergePolicy.MergeSpecification

Overrides

Lucene.Net.Index.MergePolicy.FindForcedDeletesMerges(Lucene.Net.Index.SegmentInfos)

FindForcedMerges(SegmentInfos, int, IDictionary<SegmentCommitInfo, bool>)

Determine what set of merge operations is necessary in order to merge to <= the specified segment count. Lucene.Net.Index.IndexWriter calls this when its ForceMerge(int, bool) method is called. This call is always synchronized on the Lucene.Net.Index.IndexWriter instance so only one thread at a time will call this method.

Declaration

public override MergePolicy.MergeSpecification FindForcedMerges(SegmentInfos segmentInfos, int maxSegmentCount, IDictionary<SegmentCommitInfo, bool> segmentsToMerge)

Parameters

Type	Name	Description
SegmentInfos	segmentInfos	The total set of segments in the index
int	maxSegmentCount	Requested maximum number of segments in the index (currently this is always 1)
IDictionary<SegmentCommitInfo, bool>	segmentsToMerge	Contains the specific Lucene.Net.Index.SegmentInfo instances that must be merged away. This may be a subset of all SegmentInfos. If the value is true for a given Lucene.Net.Index.SegmentInfo, that means this segment was an original segment present in the to-be-merged index; else, it was a segment produced by a cascaded merge.

Returns

Type	Description
MergePolicy.MergeSpecification

Overrides

MergePolicy.FindForcedMerges(SegmentInfos, int, IDictionary<SegmentCommitInfo, bool>)

FindMerges(MergeTrigger, SegmentInfos)

Determine what set of merge operations are now necessary on the index. Lucene.Net.Index.IndexWriter calls this whenever there is a change to the segments. This call is always synchronized on the Lucene.Net.Index.IndexWriter instance so only one thread at a time will call this method.

Declaration

public override MergePolicy.MergeSpecification FindMerges(MergeTrigger mergeTrigger, SegmentInfos segmentInfos)

Parameters

Type	Name	Description
MergeTrigger	mergeTrigger	the event that triggered the merge
SegmentInfos	segmentInfos	the total set of segments in the index

Returns

Type	Description
MergePolicy.MergeSpecification

Overrides

Lucene.Net.Index.MergePolicy.FindMerges(Lucene.Net.Index.MergeTrigger, Lucene.Net.Index.SegmentInfos)

UseCompoundFile(SegmentInfos, SegmentCommitInfo)

Returns true if a new segment (regardless of its origin) should use the compound file format. The default implementation returns true iff the size of the given mergedInfo is less or equal to Lucene.Net.Index.MergePolicy.MaxCFSSegmentSizeMB and the size is less or equal to the TotalIndexSize * Lucene.Net.Index.MergePolicy.NoCFSRatio otherwise

false

.

Declaration

public override bool UseCompoundFile(SegmentInfos infos, SegmentCommitInfo mergedInfo)

Parameters

Type	Name	Description
SegmentInfos	infos
SegmentCommitInfo	mergedInfo

Returns

Type	Description
bool

Overrides

Lucene.Net.Index.MergePolicy.UseCompoundFile(Lucene.Net.Index.SegmentInfos, Lucene.Net.Index.SegmentCommitInfo)
