Detailed Description

template<class T>
class ArrayHandle< T >

A mechanism for accessing data in GPUArray objects's.

The ArrayHandle, well, handles the data in the GPUArray. Given, e.g., an ArrayHandle<int> h(gpuarray,access_location::host, access_mode::readwrite); The user would access one of the integers via h.data[i] on the host or a direct acces on the device
