Member Function Documentation

template<class T >

bool CudaPyramidCache< T >::Item::beginSet	(	const CudaImage< T > &	img,
		rutz::mutex_lock_class *	l
	)			[inline]

Acquire an exclusive lock on the mutex so that we can set a new pyramid for the given image.

If we already have a pyramid for the given image, then the return value here will be false, indicating that there is no need to set the pyramid again.

If we do need a new pyramid for the given image, then the return value will be true and the Lock will be filled in with lock information that must be passed back to endSet().

Typical usage would look like this:

        rutz::mutex_lock_class lock;
        if (cache->gaussian5.beginSet(img, &lock))
        {
          ImageSet<float> pyr = doSomethingToComputePyramid(img);
          cache->gaussian5.endSet(img, pyr, &lock);
        }
