operator()() [1/2]

template<typename T , typename DESCRIPTOR , typename DYNAMICS >

bool olb::gpu::cuda::MaskedCollision< T, DESCRIPTOR, DYNAMICS >::operator() ( DeviceContext< T, DESCRIPTOR > & lattice, CellID iCell )

inline

Chainable call operator for use in kernel::call_operators.

Returns true iff MaskedCollision applies to iCell, enabling easy chaining by a fold expression to yield a fused collision kernel.

                                                                                 {
    if (_mask[iCell]) {
      apply(lattice, iCell);
      return true;
    }
    return false;

template<typename T , typename DESCRIPTOR , typename DYNAMICS >

bool olb::gpu::cuda::MaskedCollision< T, DESCRIPTOR, DYNAMICS >::operator() ( DeviceContext< T, DESCRIPTOR > & lattice, CellID iCell, CellStatistic< T > & statistic )
