  • Constructor Details

    • MDBStat

      public MDBStat(ByteBuffer container)
      Creates a MDBStat 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

      public int sizeof()
      Specified by:
      sizeof in class org.lwjgl.system.Struct

    • ms_psize

      public int ms_psize()
      Size of a database page. This is currently the same for all databases.

    • ms_depth

      public int ms_depth()
      Depth (height) of the B-tree.

    • ms_branch_pages

      public long ms_branch_pages()
      Number of internal (non-leaf) pages.

    • ms_leaf_pages

      public long ms_leaf_pages()
      Number of leaf pages.

    • ms_overflow_pages

      public long ms_overflow_pages()
      Number of overflow pages.

    • ms_entries

      public long ms_entries()
      Number of data items.
