Detailed Description

template<class T, int N, int S>
class ltl::FVMemory< T, N, S >

Memory and data access interface for ltl::FVMemory.

The ltl::FVMemory objects implement the memory access interface of the ltl::FVector object, i.e. operator() for 1-based access and operator[] for 0-based access. References N objects of type T accessible through a T* with stride S.

The template parameter S is the stride which may be != 1, such that column vectors of ltl::FVMatrix can be referenced as ltl::FVector objects.

There is a general implementation (this one) and a specialization for S=0. S!=0 indicates that this instance is a reference to foreign storage. S is then the stride used to access the memory elements. The specialization for S=0 below is used for instances that hold there own memory (i.e. ltl::FVector objects) that have their own memory, not references to other ltl::FVector objects. In this case the physical stride is one.

FVMemory does not require more memory than is necessary to store the N elements of the vector if S=0. If S>0, the size is exactly sizeof(T*).
