RectangleExample的内容和LineExample几乎相同，画Line和画Rectangle的方法和类似的图形画法在以后的文章里面总结一次，暂时不作过多记录。

 

- NEAREST: Faster then BILINEAR as only the nearest pixel on the Texture is used (Sprites tend to look pixelated when, physical resolution is higher or lower than texture resolution. Up/Down-scaling)
- BILINEAR: Slower than NEAREST, but looks better, as not only one pixel from the texture is fetched but the 4 nearest.

The difference between those and the REPEATING TextureOptions is the way OpenGL treats TextureCoordinates that are out of the physical bounds of the Texture (usually ranging from 0.0 to 1.0).
Where REPEATING paints the Texture twice when the coordinates go from 0.0 to 2.0, NON-REPEATING will stretch the outermost pixel of the Texture what looks pretty ugly.

So the REPEATING TextureOptions are used only in very special cases.

HashSet中迭代器的使用

Iterator itOfSys=hashSetOfSys.iterator();
		Iterator itOfSelf=hashSetOfSys.iterator();
		
		while(itOfSys.hasNext())//Iterator与cursor一样的读取模式
		{
			Object objectOfSys =itOfSys.next();
			
			while(itOfSelf.hasNext())
			{
				Object objectOfSelf = itOfSelf.next();
				if(objectOfSys.equals(objectOfSelf))//匹配到了，如果系统的包含自己的，说明不需要改变
				{
					break;
				}
				else//没有匹配到，说明系统有的，我们没有，需要被添加
				{
					listToBeAdd.add(objectOfSys);
				}
				objectOfSelf = null;
			}
			objectOfSys = null;
			
		}
