      • write

        void write​(long insertTime,
           java.lang.Object objectValue)

      • writeAlignedValue

        void writeAlignedValue​(long insertTime,
                       java.lang.Object[] objectValue,
                       java.util.List<org.apache.iotdb.tsfile.write.schema.IMeasurementSchema> schemaList)

      • write

           int start,
           int end)
        write data in the range [start, end). Null value in the valueList will be replaced by the subsequent non-null value, e.g., {1, null, 3, null, 5} will be {1, 3, 5, null, 5}

      • writeAlignedValues

        void writeAlignedValues​(long[] times,

      • count

        long count()

      • getSchema

        org.apache.iotdb.tsfile.write.schema.IMeasurementSchema getSchema()

      • getSortedTvListForQuery

        TVList getSortedTvListForQuery()
        served for query requests.

        if tv list has been sorted, just return reference of it

        if tv list hasn't been sorted and has no reference, sort and return reference of it

        if tv list hasn't been sorted and has reference we should copy and sort it, then return ths list

        the mechanism is just like copy on write

        This interface should be synchronized for concurrent with sortTvListForFlush

        Returns:
        sorted tv list

      • getSortedTvListForQuery

        TVList getSortedTvListForQuery​(java.util.List<org.apache.iotdb.tsfile.write.schema.IMeasurementSchema> schemaList)
        served for vector query requests.

        the mechanism is just like copy on write

        This interface should be synchronized for concurrent with sortTvListForFlush

        Returns:
        sorted tv list

      • sortTvListForFlush

        void sortTvListForFlush()
        served for flush requests. The logic is just same as getSortedTVListForQuery, but without add reference count

        This interface should be synchronized for concurrent with getSortedTvListForQuery

      • getTVList

        default TVList getTVList()

      • getMinTime

        default long getMinTime()

      • delete

        int delete​(long lowerBound,
           long upperBound)
        Returns:
        how many points are deleted

      • createIChunkWriter

        org.apache.iotdb.tsfile.write.chunk.IChunkWriter createIChunkWriter()

      • encode

        void encode​(org.apache.iotdb.tsfile.write.chunk.IChunkWriter chunkWriter)

      • release

        void release()

      • getFirstPoint

        long getFirstPoint()

      • getLastPoint
