  • Constructor Details

    • spng_sbit

      public spng_sbit(ByteBuffer container)
      Creates a spng_sbit 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.
