Constructor & Destructor Documentation

itk::GPUKernelManager::GPUKernelManager ( )

protected

Pass to GPU both the pixel buffer and the buffered region.

itk::GPUKernelManager::~GPUKernelManager ( )

overrideprotected

Pass to GPU both the pixel buffer and the buffered region.

Member Function Documentation

bool itk::GPUKernelManager::CheckArgumentReady ( int  kernelIdx )

protected

Pass to GPU both the pixel buffer and the buffered region.

virtual::itk::LightObject::Pointer itk::GPUKernelManager::CreateAnother ( ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

int itk::GPUKernelManager::CreateKernel

(

const char *

kernelName

)

int itk::GPUKernelManager::GetCurrentCommandQueueID

(

)

Pass to GPU both the pixel buffer and the buffered region.

		cl_kernel_work_group_info	paramName,
		void *	value
	)

virtual const char* itk::GPUKernelManager::GetNameOfClass ( ) const

virtual

Return the name of this class as a string. Used by the object factory (implemented in New()) to instantiate objects of a named type. Also used for debugging and other output information.

Reimplemented from itk::LightObject.

bool itk::GPUKernelManager::LaunchKernel	(	int	kernelIdx,
		int	dim,
