我编写了一个函数,其目的是获取从重新缩放的输入图像定义的子图像的集合(这些子图像称为“重新缩放的输入图像的重新缩放的块”)并将这些重新缩放的块重新组装成输出整个图像(其尺寸是输入图像的那些,重新缩放)。所有块都具有相同的尺寸。该函数定义如下。问题是 SonarLint 警告我认知复杂度是 16 而不是 15,而且我不想更改这个默认的 SonarLint 限制。我能做什么?该功能的描述如下,代码如下:final BufferedImage reassembleChunksInASingleImage(final int inputImageWidth, final int inputImageHeight, final int scalingCoefficient, final int chunkWidth, final int chunkHeight, final List<BufferedImage> theChunks) { logger.log(Level.INFO, "Reassembling..."); final int reassembled_chunks_image_width = scalingCoefficient * inputImageWidth; final int reassembledChunksImageHeight = scalingCoefficient * inputImageHeight; final int rescaled_chunk_width = scalingCoefficient * chunkWidth; final int rescaledChunkHeight = scalingCoefficient * chunkHeight; final BufferedImage reassembledChunksImage = new BufferedImage(reassembled_chunks_image_width, reassembledChunksImageHeight, BufferedImage.TYPE_INT_RGB); int indexOfTheChunkToUse = 0; for(int i = 0; i < reassembled_chunks_image_width; i += rescaled_chunk_width) { for(int j = 0; j < reassembledChunksImageHeight; j += rescaledChunkHeight) { final BufferedImage chunkToUse = theChunks.get(indexOfTheChunkToUse); int iForDraw = i; int jForDraw = j; final int deltaI = reassembled_chunks_image_width - (i + rescaled_chunk_width); final int deltaJ = reassembledChunksImageHeight - (j + rescaledChunkHeight); if(deltaI < 0) { iForDraw -= Math.abs(deltaI); }我浏览重新缩放的图像,用块的足够(x 轴或 y 轴)尺寸(所有块具有相同的尺寸)增加水平或垂直移位。相关循环是:for(int i = 0; i < reassembled_chunks_image_width; i += rescaled_chunk_width) {for(int j = 0; j < reassembledChunksImageHeight; j += rescaledChunkHeight) {我将当前重新缩放图像的像素颜色设置为当前块的颜色之一。相关循环是:for(int x = 0; x < rescaled_chunk_width; x++) {for(int y = 0; y < rescaledChunkHeight; y++) {.如果当前块超出了重新缩放图像的范围,我会将其移动到左侧或顶部,然后绘制它。相关控件是:if(deltaI < 0) {if(deltaJ < 0) {.

你可以尝试重构你的方法,例如
int iForDraw = getDraw(reassembled_chunks_image_width, rescaled_chunk_width, i);
int jForDraw = getDraw(reassembledChunksImageHeight, rescaledChunkHeight, j);
添加一个小方法,例如 getDraw
private int getDraw(int reassembled_chunks_image_data, int rescaled_chunk_data, int index) {
int result = index;
int delta = reassembled_chunks_image_data - (index + rescaled_chunk_data);
if (delta < 0) {
result -= Math.abs(delta);
}
return result;
}
