 Implementation (const T &defaultValue, int numCacheEntries=1)
 
 Implementation (int numCacheEntries=1)
 Argument numCacheEntries should be one greater than the number of derivatives; that is, there is room for the value ("0th" derivative) also. More...

 Copy constructor copies the number of cache entries from the source, but not the cache indices themselves as those must be allocated uniquely for the copy. More...
 
int size () const

Change the value of this Measure in the given state.

Invalidates cache entries in that state for any stage at or above the "invalidates" stage that was set when this Measure was constructed.

This is only called when derivOrder >= the number of cache entries we have, but still <= the number of derivatives the Measure says it can deliver.

You don't need to override this if that condition can't occur. This is commonly used for functions whose derivatives above a certain order are zero.

Concrete measures can override this to allocate Topology-stage resources.
