gr_cb

template<typename T >

using gr_cb = gr_sp<T, &T::refCommandBuffer, &T::unrefCommandBuffer>

Shared pointer class to wrap classes that support a refCommandBuffer() and unrefCommandBuffer() interface.

This class supports copying, moving, and assigning an sk_sp into it. In general these commands do not modify the sk_sp at all but just call refCommandBuffer() on the underlying object.

This class is designed to be used by GrGpuResources/graphite::Resources that need to track when they are in use on gpu (usually via a command buffer) separately from tracking if there are any current logical usages in Skia. This allows for a scratch resources to be reused for new draw calls even if it is in use on the GPU.

gr_rp

template<typename T >

using gr_rp = gr_sp<T, &T::ref, &T::recycle>

This class mimics sk_sp but instead of calling unref it calls recycle instead.

                                                       {
    return gr_rp<T>(const_cast<T*>(SkSafeRef(obj)));
}

gr_ref_rp() [2/2]

template<typename T >

gr_rp< T > gr_ref_rp

(

T *

obj

)

Returns a gr_rp wrapping the provided ptr AND calls ref on it (if not null).

This is different than the semantics of the constructor for gr_rp, which just wraps the ptr, effectively "adopting" it.

{ return gr_rp<T>(SkSafeRef(obj)); }
