Detailed Description

template<unsigned int N>
class CxxUtils::ArrayIterator< N >::pointer

Proxy to return from operator>.

operator-> is required to either return an actual C++ pointer or another object that has a valid operator->. This makes things a bit tricky if you're using proxies. We have the ArrayIterator operator-> return an instance of this proxy class, which contains an instance of the Array proxy. The operator-> of this proxy then returns a pointer to the contained Array. This will work for most common usages. However, the pointer one gets from the operator-> here will only be valid until the proxy is destroyed.
