Detailed Description
Mock implementation of a native compositor.
Field Documentation
◆ acquire_image
| xrt_result_t(* mock_compositor::acquire_image) (struct mock_compositor *mc, struct mock_compositor_swapchain *mcsc, uint32_t *out_index) |
Optional function pointer, called during xrt_swapchain::acquire_image.
◆
| struct { ... } mock_compositor::compositor_hooks |
Optional function pointers you can populate to hook into the behavior of the mock compositor implementation.
Providing a function pointer will disable any built-in functionality in the mock for most of these fields. While you can populate these with a lambda, because they're plain function pointers, you can't have any captures, so use mock_compositor::userdata to read or write any data from the outside world.
◆ create_swapchain
| xrt_result_t(* mock_compositor::create_swapchain) (struct mock_compositor *mc, struct mock_compositor_swapchain *mcsc, const struct xrt_swapchain_create_info *info, struct xrt_swapchain **out_xsc) |
Optional function pointer for mock compositor, called during xrt_comp_create_swapchain.
Takes the extra parameter of the typed pointer to the in-progress swapchain mcsc , which is allocated and has basic values populated for it, even if this function pointer is set.
◆ destroy
| void(* mock_compositor::destroy) (struct mock_compositor *mc, struct mock_compositor_swapchain *mcsc) |
Optional function pointer for mock compositor, called during xrt_comp_destroy (before actual destruction)
Optional function pointer, called during xrt_swapchain::destroy (before actual destruction)
The actual destruction is done by the mock implementation whether or not you populate this field.
◆ get_swapchain_create_properties
| xrt_result_t(* mock_compositor::get_swapchain_create_properties) (struct mock_compositor *mc, const struct xrt_swapchain_create_info *info, struct xrt_swapchain_create_properties *xsccp) |
Optional function pointer for mock compositor, called during xrt_comp_get_swapchain_create_properties.
◆ import_swapchain
| xrt_result_t(* mock_compositor::import_swapchain) (struct mock_compositor *mc, struct mock_compositor_swapchain *mcsc, const struct xrt_swapchain_create_info *info, struct xrt_image_native *native_images, uint32_t image_count, struct xrt_swapchain **out_xsc) |
Optional function pointer for mock compositor, called during xrt_comp_import_swapchain.
Takes the extra parameter of the typed pointer to the in-progress swapchain mcsc , which is allocated and has basic values populated for it, even if this function pointer is set. Does not release the native images passed in if this function pointer is set, so you will have to do that yourself.
◆ next_id
| uint32_t mock_compositor::next_id |
ID for next swapchain.
◆ release_image
| xrt_result_t(* mock_compositor::release_image) (struct mock_compositor *mc, struct mock_compositor_swapchain *mcsc, uint32_t index) |
Optional function pointer, called during xrt_swapchain::release_image.
◆
| struct { ... } mock_compositor::swapchain_hooks |
Optional function pointers you can populate to hook into the behavior of the mock swapchain implementation.
Providing a function pointer will disable any built-in functionality in the mock for most of these fields. While you can populate these with a lambda, because they're plain function pointers, you can't have any captures, so use mock_compositor::userdata to read or write any data from the outside world.
◆ userdata
| void* mock_compositor::userdata |
Mock users can populate this pointer to use data from hooks.
◆ wait_image
| xrt_result_t(* mock_compositor::wait_image) (struct mock_compositor *mc, struct mock_compositor_swapchain *mcsc, uint64_t timeout_ns, uint32_t index) |
Optional function pointer, called during xrt_swapchain::wait_image.
