`protected class` | `SnapshotDeletionPolicy.SnapshotCommitPoint` Wraps a provided `IndexCommit` and prevents it from being deleted.

Fields in org.apache.lucene.index declared as IndexCommit
`protected IndexCommit` | `LiveIndexWriterConfig.commit` `IndexCommit` that `IndexWriter` is opened on.
`protected IndexCommit` | `SnapshotDeletionPolicy.SnapshotCommitPoint.cp` The `IndexCommit` we are preventing from deletion.
`protected IndexCommit` | `SnapshotDeletionPolicy.lastCommit` Most recently committed `IndexCommit`.

Methods in org.apache.lucene.index that return IndexCommit
`IndexCommit` | `LiveIndexWriterConfig.getIndexCommit()` Returns the `IndexCommit` as specified in `IndexWriterConfig.setIndexCommit(IndexCommit)` or the default, `null` which specifies to open the latest index commit point.
`IndexCommit` | `IndexWriterConfig.getIndexCommit()`
`IndexCommit` | `FilterDirectoryReader.getIndexCommit()`
`abstract IndexCommit` | `DirectoryReader.getIndexCommit()` Expert: return the IndexCommit that this reader has opened.
`IndexCommit` | `SnapshotDeletionPolicy.getSnapshot(String id)` Get a snapshotted IndexCommit by ID.
`IndexCommit` | `SnapshotDeletionPolicy.snapshot(String id)` Snapshots the last commit.
`IndexCommit` | `PersistentSnapshotDeletionPolicy.snapshot(String id)` Snapshots the last commit using the given ID.

Methods in org.apache.lucene.index that return types with arguments of type IndexCommit
`static List<IndexCommit>` | `DirectoryReader.listCommits(Directory dir)` Returns all commit points that exist in the Directory.
`protected List<IndexCommit>` | `SnapshotDeletionPolicy.wrapCommits(List<? extends IndexCommit> commits)` Wraps each `IndexCommit` as a `SnapshotDeletionPolicy.SnapshotCommitPoint`.

Methods in org.apache.lucene.index with parameters of type IndexCommit
`int` | `IndexCommit.compareTo(IndexCommit commit)`
`protected DirectoryReader` | `FilterDirectoryReader.doOpenIfChanged(IndexCommit commit)`
`protected abstract DirectoryReader` | `DirectoryReader.doOpenIfChanged(IndexCommit commit)` Implement this method to support `DirectoryReader.openIfChanged(DirectoryReader,IndexCommit)`.
`static DirectoryReader` | `IndexReader.open(IndexCommit commit)` Deprecated. Use `DirectoryReader.open(IndexCommit)`
`static DirectoryReader` | `DirectoryReader.open(IndexCommit commit)` Expert: returns an IndexReader reading the index in the given `IndexCommit`.
`static DirectoryReader` | `IndexReader.open(IndexCommit commit, int termInfosIndexDivisor)` Deprecated. Use `DirectoryReader.open(IndexCommit,int)`
`static DirectoryReader` | `DirectoryReader.open(IndexCommit commit, int termInfosIndexDivisor)` Expert: returns an IndexReader reading the index in the given `IndexCommit` and termInfosIndexDivisor.
`static DirectoryReader` | `DirectoryReader.openIfChanged(DirectoryReader oldReader, IndexCommit commit)` If the IndexCommit differs from what the provided reader is searching, open and return a new reader; else, return null.
`protected void` | `SnapshotDeletionPolicy.registerSnapshotInfo(String id, String segment, IndexCommit commit)` Registers the given snapshot information.
`Object` | `SegmentInfos.FindSegmentsFile.run(IndexCommit commit)` Run `SegmentInfos.FindSegmentsFile.doBody(java.lang.String)` on the provided commit.
`IndexWriterConfig` | `IndexWriterConfig.setIndexCommit(IndexCommit commit)` Expert: allows to open a certain commit point.

Method parameters in org.apache.lucene.index with type arguments of type IndexCommit
`void` | `SnapshotDeletionPolicy.onCommit(List<? extends IndexCommit> commits)`
`void` | `NoDeletionPolicy.onCommit(List<? extends IndexCommit> commits)`
`void` | `KeepOnlyLastCommitDeletionPolicy.onCommit(List<? extends IndexCommit> commits)` Deletes all commits except the most recent one.
`abstract void` | `IndexDeletionPolicy.onCommit(List<? extends IndexCommit> commits)` This is called each time the writer completed a commit.
`void` | `SnapshotDeletionPolicy.onInit(List<? extends IndexCommit> commits)`
`void` | `PersistentSnapshotDeletionPolicy.onInit(List<? extends IndexCommit> commits)`
`void` | `NoDeletionPolicy.onInit(List<? extends IndexCommit> commits)`
`void` | `KeepOnlyLastCommitDeletionPolicy.onInit(List<? extends IndexCommit> commits)` Deletes all commits except the most recent one.
`abstract void` | `IndexDeletionPolicy.onInit(List<? extends IndexCommit> commits)` This is called once when a writer is first instantiated to give the policy a chance to remove old commit points.
`protected List<IndexCommit>` | `SnapshotDeletionPolicy.wrapCommits(List<? extends IndexCommit> commits)` Wraps each `IndexCommit` as a `SnapshotDeletionPolicy.SnapshotCommitPoint`.

Constructors in org.apache.lucene.index with parameters of type IndexCommit
`SnapshotDeletionPolicy.SnapshotCommitPoint(IndexCommit cp)` Creates a `SnapshotCommitPoint` wrapping the provided `IndexCommit`.
