Class POINTL

  • All Implemented Interfaces:
    java.lang.AutoCloseable, NativeResource, Pointer


    public class POINTL
    extends Struct
    Contains the coordinates of a point.

    Member documentation

    • x – the horizontal (x) coordinate of the point
    • y – the vertical (y) coordinate of the point.

    Layout

    struct POINTL {
        LONG x;
        LONG y;
    }
    • Field Detail

      • SIZEOF

        public static final int SIZEOF
        The struct size in bytes.
    • 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.
