WritableMemory.wrap介绍

[英]Accesses the given ByteBuffer for write operations. The returned WritableMemory object has the same byte order, as the given ByteBuffer, unless the capacity of the given ByteBuffer is zero, then byte order of the returned WritableMemory object, as well as backing storage and read-only status are unspecified.

Note: Always qualify this method with the class name, e.g., WritableMemory.wrap(...).
[中]访问给定的字节缓冲区进行写操作。返回的WritableMemory对象与给定字节缓冲区具有相同的字节顺序，除非给定字节缓冲区的容量为零，否则返回的WritableMemory对象的字节顺序以及后备存储和只读状态均未指定。
注意：始终使用类名限定此方法，例如WritableMemory。包裹（…）。
