Detailed Description

template<class Type, unsigned Dim>
class Cuda::Storage< Type, Dim >

Class to represent memory that can be allocated and freed.

This is used as a virtual base class for all types of memory for which the CUDA templates should perform their own memory management (i.e., allocation and deallocation).

Constructor & Destructor Documentation

template<class Type, unsigned Dim>

Cuda::Storage< Type, Dim >::Storage

(

const Size< Dim > &

_size

)

[inline]

Constructor.

Parameters:

_size

requested size

template<class Type, unsigned Dim>

Cuda::Storage< Type, Dim >::Storage

(

const Layout< Type, Dim > &

layout

)

[inline]

Constructor.

See Storage::alloc(const Layout<Type, Dim> &) for possible performance implications.

Parameters:

template<class Type, unsigned Dim>

void Cuda::Storage< Type, Dim >::alloc

(

const Layout< Type, Dim > &

layout

)

[inline]

Allocate memory.

This uses the requested layout regardless of constraints imposed by subclasses (such as DeviceMemoryPitched). Use with care to avoid performance penalties!

Parameters:

layout

requested layout

template<class Type, unsigned Dim>

const Layout<Type, Dim>& Cuda::Storage< Type, Dim >::getLayout

(

)

const [inline]

Get current layout.

Returns:

layout

template<class Type, unsigned Dim>

virtual void Cuda::Storage< Type, Dim >::init

(

)

[pure virtual]

Initialize data structure.

Subclasses should use this method to initialize their internal data representation to a defined "empty" state.

Implemented in Cuda::Array< Type, Dim >, Cuda::DeviceMemoryStorage< Type, Dim >, Cuda::HostMemoryStorage< Type, Dim >, Cuda::PointerStorage< Type, Dim >, Cuda::OpenGL::Texture< Type, Dim >, Cuda::Array< Type, 1 >, Cuda::Array< Type, 2 >, Cuda::Array< Type, 3 >, Cuda::OpenGL::Texture< Type, 1 >, Cuda::OpenGL::Texture< Type, 2 >, and Cuda::OpenGL::Texture< Type, 3 >.
