包路径：com.adobe.xmp.XMPMeta
类名称：XMPMeta

XMPMeta介绍

[英]This class represents the set of XMP metadata as a DOM representation. It has methods to read and modify all kinds of properties, create an iterator over all properties and serialize the metadata to a String, byte-array or OutputStream.
[中]此类将XMP元数据集表示为DOM表示。它具有读取和修改各种属性、对所有属性创建迭代器以及将元数据序列化为字符串、字节数组或OutputStream的方法。
