      • CompactValue

        public CompactValue​(java.nio.ByteBuffer container)
        Creates a CompactValue 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 Detail

      • sizeof

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

        public float value()
        Returns the value of the value field.
      • repr

        public int repr()
        Returns the value of the repr field.
      • create

        public static CompactValue create​(long address)
        Returns a new CompactValue instance for the specified memory address.
      • createSafe

        @Nullable
        public static CompactValue createSafe​(long address)
        Like create, but returns null if address is NULL.
      • create

        public static CompactValue.Buffer create​(long address,
                                                 int capacity)
