Public Constructors
RWTValVirtualArray<T>(long size, RWVirtualPageHeap* heap);
Construct a vector of length size. The pages for the vector will be allocated from the page
heap given by heap which can be of any type.
RWTValVirtualArray<T>(const RWTValVirtualArray<T>& v);
Constructs a vector as a copy of v. The resultant vector will use the same heap and have
the same length as v. The actual copy will not be made until a write, minimizing the
amount of heap allocations and copying that must be done.
RWTValVirtualArray<T>(const RWTVirtualSlice<T>& sl);
Constructs a vector from a slice of another vector. The resultant vector will use the same
heap as the vector whose slice is being taken. Its length will be given by the length of the
slice. The copy will be made immediately.
