caffe中的'this'是什么？

Question

早上好 我对深度学习中的咖啡有疑问

在conv_layer.cpp

中

#include <vector>

#include "caffe/layers/conv_layer.hpp"

namespace caffe {

template <typename Dtype>
void ConvolutionLayer<Dtype>::compute_output_shape() {
  const int* kernel_shape_data = this->kernel_shape_.cpu_data();
  const int* stride_data = this->stride_.cpu_data();
  const int* pad_data = this->pad_.cpu_data();
  const int* dilation_data = this->dilation_.cpu_data();
  this->output_shape_.clear();
  for (int i = 0; i < this->num_spatial_axes_; ++i) {
    // i + 1 to skip channel axis
    const int input_dim = this->input_shape(i + 1);
    const int kernel_extent = dilation_data[i] * (kernel_shape_data[i] - 1) + 1;
    const int output_dim = (input_dim + 2 * pad_data[i] - kernel_extent)
        / stride_data[i] + 1;
    this->output_shape_.push_back(output_dim);
  }
}

在此代码中，

上的'this'是什么

'这 - ＆GT; kernel_shape_.cpu_data（）;'像这样

我想知道'this'的用法

谢谢
