This is a supporting class for MemoryUsage.
size_t get_size() const
Returns the total allocated size of all pointers in the count whose size is known.
int get_count() const
Returns the total number of pointers in the count.
void clear()
Resets the counter to empty.
bool is_size_unknown() const
Returns true if none of the pointers in the count have a known size, or false if at least one of them...
void add_info(MemoryInfo *info)
Adds a pointer definition to the counter.
