One-block method

This method processes one block at a time and stores the output (the encrypted result) in the ivBytes array.

这个方法一次处理一块并将输出（加密的结果）储存在 ivBytes数组中。

The respond_to method accepts a single code block and passes one instance variable (labeled wants) into the code block.

respond _ to方法接受单个代码块，并传递一个实例变量(标为wants)到代码块。

When you select one of those blocks of code and do a refactoring, Eclipse finds other occurrences of that block of code and replaces it with a call to the new method.

当选择这些代码块中的某一个代码块进行重构时，Eclipse将找到出现这个代码块的其他地方，并用一个对这个新方法的调用替代它。
