  • Constructor Details

    • MDBEnvInfo

      public MDBEnvInfo(ByteBuffer container)
      Creates a MDBEnvInfo instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.

  • Method Details

    • sizeof

      public int sizeof()
      Description copied from class: Struct
      Returns sizeof(struct).
      Specified by:
      sizeof in class Struct<MDBEnvInfo>

      public long me_last_pgno()
      Returns:
      the value of the me_last_pgno field.

    • me_last_txnid

      public long me_last_txnid()
      Returns:
      the value of the me_last_txnid field.
