fill()

template<class T , unsigned int N>

__host__ __device__ void amrex::GpuArray< T, N >::fill ( const T &  value )

inlinenoexcept

Fills in all of the elements in the GpuArray object to the same value.

Parameters

value

The fill value

operator+=()

template<class T , unsigned int N>

__host__ __device__ GpuArray< T, N > & amrex::GpuArray< T, N >::operator+= ( GpuArray< T, N > const &  a )

inlinenoexcept

operator[]() [1/2]

template<class T , unsigned int N>

__host__ __device__ const T & amrex::GpuArray< T, N >::operator[] ( int  i ) const

inlinenoexcept

GpuArray elements are indexed using square brackets, as with any other array.

operator[]() [2/2]

template<class T , unsigned int N>

__host__ __device__ T & amrex::GpuArray< T, N >::operator[] ( int  i )

inlinenoexcept
