    • getTimestamp

      public long getTimestamp()
      Description copied from interface: Cell
      Return a long value representing time at which this cell was "Put" into the row. Typically represents the time of insertion, but can be any value from 0 to Long.MAX_VALUE.
      Specified by:
      getTimestamp in interface Cell

    • getTypeByte

      public byte getTypeByte()
      Description copied from interface: ExtendedCell
      Returns The byte representation of the KeyValue.TYPE of this cell: one of Put, Delete, etc
      Specified by:
      getTypeByte in interface ExtendedCell

    • getType

      public Cell.Type getType()
      Description copied from interface: ExtendedCell
      Typically, at server side, you'd better always use the ExtendedCell.getTypeByte() as this method does not expose the Maximum and Minimum because they will not be returned to client, but at server side, we do have cells with these types so if you use this method it will cause exceptions.
      Specified by:
      getType in interface Cell
      Specified by:
      getType in interface ExtendedCell
      Returns:
      The data type this cell: one of Put, Delete, etc

    • getSequenceId

      public long getSequenceId()
      Description copied from interface: ExtendedCell
      A region-specific unique monotonically increasing sequence ID given to each Cell. It always exists for cells in the memstore but is not retained forever. It will be kept for HConstants.KEEP_SEQID_PERIOD days, but generally becomes irrelevant after the cell's row is no longer involved in any operations that require strict consistency.
      Specified by:
      getSequenceId in interface ExtendedCell
      Returns:
      seqId (always > 0 if exists), or 0 if it no longer exists

    • getValueArray

      public byte[] getValueArray()
      Description copied from interface: Cell
      Contiguous raw bytes that may start at any index in the containing array. Max length is Integer.MAX_VALUE which is 2,147,483,647 bytes.
      Specified by:
      getValueArray in interface Cell
      Returns:
      The array containing the value bytes.

      Specified by:
      getValueOffset in interface Cell

    • getValueLength

      public int getValueLength()
      Description copied from interface: Cell

      Specified by:
      getSerializedSize in interface Cell
      Specified by:
      getSerializedSize in interface ExtendedCell

    • getTagsArray

      public byte[] getTagsArray()
      Description copied from interface: RawCell
      Contiguous raw bytes representing tags that may start at any index in the containing array.

    • getTagsOffset

      public int getTagsOffset()
      Description copied from interface: RawCell
      Return the first offset where the tags start in the Cell
      Specified by:
      getTagsOffset in interface RawCell

    • getTagsLength

      public int getTagsLength()
      Description copied from interface: RawCell
      HBase internally uses 2 bytes to store tags length in Cell. As the tags length is always a non-negative number, to make good use of the sign bit, the max of tags length is defined 2 * Short.MAX_VALUE + 1 = 65535. As a result, the return type is int, because a short is not capable of handling that. Please note that even if the return type is int, the max tags length is far less than Integer.MAX_VALUE.
      Specified by:
      getTagsLength in interface RawCell
      Returns:
      the total length of the tags in the Cell.

    • heapSize

      public long heapSize()
      Description copied from interface: HeapSize
      Return the approximate 'exclusive deep size' of implementing object. Includes count of payload and hosting object sizings.
      Specified by:
      heapSize in interface HeapSize
