Patch\n 3/3 showcases how internal functions can be hidden from the public API\n by moving them to the Private data class.\n\nThis v2 incorporates parts of the comments from reviews of v1. There are\nstill some ongoing discussions, which may benefit from patch 2/3 (new in\nv2) that shows how the _d() function can be used directly instead of\nusing the LIBCAMERA_D_PTR macro.\n\nLaurent Pinchart (3):\n libcamera: base: class: Expose Extensible private data to other\n classes\n libcamera: Drop the LIBCAMERA_D_PTR macro in favour of the _d()\n function\n libcamera: framebuffer: Make FrameBuffer class Extensible\n\n include/libcamera/base/class.h | 16 ++++++---\n include/libcamera/framebuffer.h | 8 ++---\n include/libcamera/internal/framebuffer.h | 13 +++++++\n src/android/camera_buffer.h | 15 +++-----\n src/android/camera_hal_config.cpp | 3 +-\n src/libcamera/base/class.cpp | 17 +++------\n src/libcamera/camera.cpp | 44 +++++++++---------------\n src/libcamera/camera_manager.cpp | 16 ++++-----\n src/libcamera/framebuffer.cpp | 34 ++++++++++--------\n src/libcamera/pipeline/ipu3/cio2.cpp | 3 +-\n src/libcamera/pipeline/ipu3/frames.cpp | 5 +--\n src/libcamera/request.cpp | 7 ++--\n 12 files changed, 91 insertions(+), 90 deletions(-)" }
