The Attributes class maps Manifest attribute names to associated string

values. Valid attribute names are case-insensitive, are restricted to

the ASCII characters in the set [0-9a-zA-Z_-], and cannot exceed 70

characters in length. Attribute values can contain any characters and

will be UTF8-encoded when written to the output stream. See the

<a href="../../../../guide/jar/jar.html">JAR File Specification</a>

for more information about valid attribute names and values.

Attributes类将Manifest属性名映射为对应的字符串值。属性名忽略大小写，但被限制为[0-9a-zA-Z_-]集中的ASCII字符，

长度不能超出70。属性值可以包含任意字符，以UTF-8编码输出到输出流。有效属性名和属性值的更多信息查看JAR文件规范。

返回true。

clone</H3>

<PRE>

public <A HREF="../../../java/lang/Object.html" title="class in java.lang">Object</A> clone()</PRE>

<DL>

<DD>Returns a copy of the Attributes, implemented as follows:

返回该Attributes的拷贝。按以下实现。

<pre>

public Object clone() { return new Attributes(this); }

</pre>

Since the attribute names and values are themselves immutable,

the Attributes returned can be safely modified without affecting

the original.

由于属性名和值本身不可变，所以返回的Attributes可以被安全修改而不影响原值。
