Definition at line 26 of file rpc/solvers/Mixture.h.

Member Typedef Documentation

◆ ElementType

template<int D>

double Pscf::Prdc::Cpu::RField< D >::ElementType

Type of each array element.

Definition at line 36 of file cpu/RField.h.

Constructor & Destructor Documentation

◆ RField() [1/2]

template<int D>

Pscf::Prdc::Cuda::RField< D >::RField ( )

Default constructor.

Definition at line 23 of file cpu/RField.tpp.

◆ RField() [2/2]

template<int D>

Pscf::Prdc::Cuda::RField< D >::RField ( const RField< D > & other )

Copy constructor.

Allocates new memory and copies all elements by value.

Parameters

other the RField to be copied.

Definition at line 43 of file cpu/RField.tpp.

References Pscf::Prdc::Cpu::FftwDArray< Data >::isAllocated().

◆ ~RField()

template<int D>

Pscf::Prdc::Cuda::RField< D >::~RField ( )

virtual

Destructor.

Deletes underlying C array, if allocated previously.

Definition at line 32 of file cpu/RField.tpp.

Member Function Documentation

◆ operator=()

template<int D>

RField< D > & Pscf::Prdc::Cuda::RField< D >::operator= ( const RField< D > & other )

Assignment operator.

If this Field is not allocated, allocates and copies all elements.

If this and the other Field are both allocated, the capacities must be exactly equal. If so, this method copies all elements.

Parameters

other the RHS RField

◆ allocate()

template<int D>

void Pscf::Prdc::Cuda::RField< D >::allocate ( IntVec< D > const & meshDimensions )

Allocate the underlying C array for an FFT grid.

Exceptions

Exception if the RField is already allocated.

Parameters

meshDimensions vector of numbers of grid points per direction
