Unsafe.addressSize介绍

[英]Report the size in bytes of a native pointer, as stored via #putAddress. This value will be either 4 or 8. Note that the sizes of other primitive types (as stored in native memory blocks) is determined fully by their information content.
[中]报告通过#putAddress存储的本机指针的字节大小。该值将为4或8。请注意，其他基本类型（存储在本机内存块中）的大小完全由其信息内容决定。
