    • Constructor Detail

      • EGLClientPixmapHI

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

      • pData

        public java.nio.ByteBuffer pData​(int capacity)
        Parameters:
        capacity - the number of elements in the returned buffer
        Returns:
        pointer to a memory buffer allocated by the application that will contain the result of the drawing operations. It is up to the application to ensure that the buffer size corresponds to iHeight * iStride * sizeof(pixel).

      • iWidth

        public int iWidth()
        width of the buffer in pixels

      • iHeight

        public int iHeight()
        height of the buffer in pixels. The height of the buffer can be negative; in that case the result of the drawing operations will be vertically swapped. When positive, pData will point at the bottom-left corner of the image; when negative, to the top-left corner.

      • iStride

        public int iStride()
        stride of the buffer, in pixels. It is important to note that each row of the buffer must start on 32-bit boundaries.

      • pData

        public EGLClientPixmapHI pData​(java.nio.ByteBuffer value)
        Sets the address of the specified ByteBuffer to the pData(int) field.

      • set

        public EGLClientPixmapHI set​(java.nio.ByteBuffer pData,
                             int iWidth,
                             int iHeight,
                             int iStride)
        Initializes this struct with the specified values.

      • malloc

        public static EGLClientPixmapHI malloc()
        Returns a new EGLClientPixmapHI instance allocated with memAlloc. The instance must be explicitly freed.

      • calloc

        public static EGLClientPixmapHI calloc()
        Returns a new EGLClientPixmapHI instance allocated with memCalloc. The instance must be explicitly freed.

      • create

        public static EGLClientPixmapHI create()
        Returns a new EGLClientPixmapHI instance allocated with BufferUtils.

      • create

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

      • createSafe

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

      • createSafe

        @Nullable
public static EGLClientPixmapHI.Buffer createSafe​(long address,
                                                  int capacity)
        Like create, but returns null if address is NULL.
