ensure()

void blender::CacheMutex::ensure

(

FunctionRef< void()>

compute_cache

)

Make sure the cache exists and is up to date. This calls compute_cache once to update the cache (which is stored outside of this class) if it is dirty, otherwise it does nothing.

This function is thread-safe under the assumption that the same parameters are passed from every thread.
