    java.lang.AutoCloseable, NativeResource, Pointer
    public class POINTL
extends Struct
implements NativeResource
    Contains the coordinates of a point.

    Layout

    
 struct POINTL {
     LONG x;
     LONG y;
 }

      • SIZEOF

        The struct size in bytes.

      • ALIGNOF

        The struct alignment in bytes.

      • X, Y

    • Constructor Detail

      • POINTL

        public POINTL​(java.nio.ByteBuffer container)
        Creates a POINTL 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.
