Uses of MergePolicy in org.apache.lucene.index

Subclasses of MergePolicy in org.apache.lucene.index
Modifier and Type	Class	Description
`class`	`BalancedSegmentMergePolicy`	Deprecated. This class is removed in 4.0; use `TieredMergePolicy` instead.
`class`	`LogByteSizeMergePolicy`	This is a `LogMergePolicy` that measures size of a segment as the total byte size of the segment's files.
`class`	`LogDocMergePolicy`	This is a `LogMergePolicy` that measures size of a segment as the number of documents (not taking deletions into account).
`class`	`LogMergePolicy`	This class implements a `MergePolicy` that tries to merge segments into levels of exponentially increasing size, where each level has fewer segments than the value of the merge factor.
`class`	`MockRandomMergePolicy`	MergePolicy that makes random decisions for testing.
`class`	`NoMergePolicy`	A `MergePolicy` which never returns merges to execute (hence it's name).
`class`	`TieredMergePolicy`	Merges segments of approximately equal size, subject to an allowed number of segments per tier.
`class`	`UpgradeIndexMergePolicy`	This `MergePolicy` is used for upgrading all existing segments of an index when calling `IndexWriter.forceMerge(int)`.

Fields in org.apache.lucene.index declared as MergePolicy
Modifier and Type	Field	Description
`protected MergePolicy`	UpgradeIndexMergePolicy.`base`
`static MergePolicy`	NoMergePolicy.`COMPOUND_FILES`	A singleton `NoMergePolicy` which indicates the index uses compound files.
`static MergePolicy`	NoMergePolicy.`NO_COMPOUND_FILES`	A singleton `NoMergePolicy` which indicates the index does not use compound files.

Methods in org.apache.lucene.index that return MergePolicy
Modifier and Type	Method	Description
`MergePolicy`	IndexWriter.`getMergePolicy()`	Deprecated. use `IndexWriterConfig.getMergePolicy()` instead
`MergePolicy`	IndexWriterConfig.`getMergePolicy()`	Returns the current MergePolicy in use by this writer.

Methods in org.apache.lucene.index with parameters of type MergePolicy
Modifier and Type	Method	Description
`void`	IndexWriter.`setMergePolicy(MergePolicy mp)`	Deprecated. use `IndexWriterConfig.setMergePolicy(MergePolicy)` instead.
`IndexWriterConfig`	IndexWriterConfig.`setMergePolicy(MergePolicy mergePolicy)`	Expert: `MergePolicy` is invoked whenever there are changes to the segments in the index.

Constructors in org.apache.lucene.index with parameters of type MergePolicy
Constructor	Description
`UpgradeIndexMergePolicy(MergePolicy base)`	Wrap the given `MergePolicy` and intercept forceMerge requests to only upgrade segments written with previous Lucene versions.
