  • Method Details

    • buffer

      ByteBuffer buffer()
      Returns a useable buffer (i.e. one whose position and limit can be freely modified). Its limit will be set to the size of the available data in the buffer. The buffer must be treated as read-only.

    • floatBuffer

      default FloatBuffer floatBuffer()

    • intBuffer

      default IntBuffer intBuffer()

    • offset

      long offset()
      Position in the file of the start of the buffer.

    • release

      void release()
      To be called when this buffer is no longer in use. Must be called for all BufferHolders, or ChunkCache will not be able to free blocks.
