#include <itkGPUDataManager.h>
GPU memory manager implemented using OpenCL. Required by GPUImage class.
This class serves as a base class for GPU data container for GPUImage class, which is similar to ImageBase class for Image class. However, all the image-related meta data will be already stored in image class (parent of GPUImage), therefore we did not name it GPUImageBase. Rather, this class is a GPU-specific data manager that provides functionalties for CPU-GPU data synchronization and grafting GPU data.

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::Object.
Reimplemented in itk::GPUImageDataManager< ImageType >, and itk::GPUImageDataManager< GPUImage >.
