    Fields in org.apache.lucene.replicator.nrt with type parameters of type FileMetaData
    Modifier and Type | Field and Description
    --- | ---
    `Map<String,FileMetaData>` | CopyState.`files`
    `protected Map<String,FileMetaData>` | CopyJob.`files`
    `protected Map<String,FileMetaData>` | Node.`lastFileMetaData` File metadata for last sync that succeeded; we use this as a cache
    `protected List<Map.Entry<String,FileMetaData>>` | CopyJob.`toCopy`

    Methods in org.apache.lucene.replicator.nrt that return FileMetaData
    Modifier and Type | Method and Description
    --- | ---
    `FileMetaData` | Node.`readLocalFileMetaData(String fileName)` Opens the specified file, reads its identifying information, including file length, full index header (includes the unique segment ID) and the full footer (includes checksum), and returns the resulting `FileMetaData`.

    Methods in org.apache.lucene.replicator.nrt that return types with arguments of type FileMetaData
    Modifier and Type | Method and Description
    --- | ---
    `List<Map.Entry<String,FileMetaData>>` | ReplicaNode.`getFilesToCopy(Map<String,FileMetaData> files)` Compares incoming per-file identity (id, checksum, header, footer) versus what we have locally and returns the subset of the incoming files that need copying

    Method parameters in org.apache.lucene.replicator.nrt with type arguments of type FileMetaData
    Modifier and Type | Method and Description
    --- | ---
    `List<Map.Entry<String,FileMetaData>>` | ReplicaNode.`getFilesToCopy(Map<String,FileMetaData> files)` Compares incoming per-file identity (id, checksum, header, footer) versus what we have locally and returns the subset of the incoming files that need copying
    `protected CopyJob` | ReplicaNode.`launchPreCopyMerge(AtomicBoolean finished, long newPrimaryGen, Map<String,FileMetaData> files)`
    `protected abstract CopyJob` | ReplicaNode.`newCopyJob(String reason, Map<String,FileMetaData> files, Map<String,FileMetaData> prevFiles, boolean highPriority, CopyJob.OnceDone onceDone)` Start a background copying job, to copy the specified files from the current primary node.
    `protected abstract CopyJob` | ReplicaNode.`newCopyJob(String reason, Map<String,FileMetaData> files, Map<String,FileMetaData> prevFiles, boolean highPriority, CopyJob.OnceDone onceDone)` Start a background copying job, to copy the specified files from the current primary node.
    `protected abstract void` | PrimaryNode.`preCopyMergedSegmentFiles(SegmentCommitInfo info, Map<String,FileMetaData> files)` Called when a merge has finished, but before IW switches to the merged segment
