HeapByteBuffer 背后依靠的字节数组存储的是一个一个的字节,以上操作全部针对的是单个字节来的,所以并不需要考虑字节序的影响,但是如果我们想从 HeapByteBuffer 中读取写入一个 int 或者一个 double 类型的数据,那么我们就需要考虑字节序的问题了。 在介绍如何从 HeapByteBuffer 中读取或者写入一个指定基本类型数据之前...
For example, the type of the expression p.salary is double because the terminating persistent field (salary) is a double.In the expression p.teams, the terminating element is a collection-valued relationship field (teams). This expression’s type is a collection of the abstract schema type ...
