Interface Allocator<T extends NppType>

Type Parameters:

T - The data type for this allocator

public interface Allocator<T extends NppType>

Interface for an allocator. An allocator manages all memory operations for an image, be it a CPU (host) or NPP (device) image. Implementations of this interface are defined in the ImageAllocatorsCPU and ImageAllocatorsNPP class.

Method Summary

void	Copy2D(TypedPointer<T> pDst, long nDstPitch, TypedPointer<T> pSrc, long nSrcPitch, long nWidth, long nHeight) 2D copy operation for the specified memory blocks consisting of data with the type that is defined by this allocator.
void	DeviceToHostCopy2D(TypedPointer<T> pDst, long nDstPitch, TypedPointer<T> pSrc, long nSrcPitch, long nWidth, long nHeight) 2D device-to-host copy for the specified memory blocks consisting of data with the type that is defined by this allocator.
void	Free2D(TypedPointer<T> pPixels) Free the given memory
void	HostToDeviceCopy2D(TypedPointer<T> pDst, long nDstPitch, TypedPointer<T> pSrc, long nSrcPitch, long nWidth, long nHeight) 2D host-to-device copy for the specified memory blocks consisting of data with the type that is defined by this allocator.
TypedPointer<T>	Malloc2D(int nWidth, int nHeight, int[] pPitch) Allocate the specified memory block for the data type of this allocator.

Method Detail
