限定符和类型	方法和说明
List<ReadOnlyMemChunk>	TsFileResource.getReadOnlyMemChunk(PartialPath seriesPath)

类型变量类型为ReadOnlyMemChunk的org.apache.iotdb.db.engine.storagegroup中的构造器参数

构造器和说明
TsFileResource(Map<PartialPath,List<ReadOnlyMemChunk>> pathToReadOnlyMemChunkMap, Map<PartialPath,List<IChunkMetadata>> pathToChunkMetadataListMap, TsFileResource originTsFileResource) unsealed TsFile, for query
TsFileResource(PartialPath path, List<ReadOnlyMemChunk> readOnlyMemChunk, List<IChunkMetadata> chunkMetadataList, TsFileResource originTsFileResource) unsealed TsFile, for query

org.apache.iotdb.db.metadata.path中ReadOnlyMemChunk的使用

返回ReadOnlyMemChunk的org.apache.iotdb.db.metadata.path中的方法

限定符和类型	方法和说明
ReadOnlyMemChunk	AlignedPath.getReadOnlyMemChunkFromMemTable(IMemTable memTable, List<Pair<Modification,IMemTable>> modsToMemtable, long timeLowerBound)
ReadOnlyMemChunk	PartialPath.getReadOnlyMemChunkFromMemTable(IMemTable memTable, List<Pair<Modification,IMemTable>> modsToMemtable, long timeLowerBound) get the ReadOnlyMemChunk from the given MemTable.
ReadOnlyMemChunk	MeasurementPath.getReadOnlyMemChunkFromMemTable(IMemTable memTable, List<Pair<Modification,IMemTable>> modsToMemtable, long timeLowerBound)

类型变量类型为ReadOnlyMemChunk的org.apache.iotdb.db.metadata.path中的方法参数

限定符和类型	方法和说明
TsFileResource	AlignedPath.createTsFileResource(List<ReadOnlyMemChunk> readOnlyMemChunk, List<IChunkMetadata> chunkMetadataList, TsFileResource originTsFileResource)
TsFileResource	PartialPath.createTsFileResource(List<ReadOnlyMemChunk> readOnlyMemChunk, List<IChunkMetadata> chunkMetadataList, TsFileResource originTsFileResource)
TsFileResource	MeasurementPath.createTsFileResource(List<ReadOnlyMemChunk> readOnlyMemChunk, List<IChunkMetadata> chunkMetadataList, TsFileResource originTsFileResource)
AlignedTimeSeriesMetadata	AlignedPath.generateTimeSeriesMetadata(List<ReadOnlyMemChunk> readOnlyMemChunk, List<IChunkMetadata> chunkMetadataList) Because the unclosed tsfile don't have TimeSeriesMetadata and memtables in the memory don't have chunkMetadata, but query will use these, so we need to generate it for them.
ITimeSeriesMetadata	PartialPath.generateTimeSeriesMetadata(List<ReadOnlyMemChunk> readOnlyMemChunk, List<IChunkMetadata> chunkMetadataList)
ITimeSeriesMetadata	MeasurementPath.generateTimeSeriesMetadata(List<ReadOnlyMemChunk> readOnlyMemChunk, List<IChunkMetadata> chunkMetadataList) Because the unclosed tsfile don't have TimeSeriesMetadata and memtables in the memory don't have chunkMetadata, but query will use these, so we need to generate it for them.
