<span>Interface AttributeSet指定一组打印属性的接口。</span>
|
||||
<span>打印属性是类实现接口<a href="../../../javax/print/attribute/Attribute.html" title="javax.print.attribute中的接口"><code>Attribute</code></a>的对象。</span>
|
||||
<p> <span>属性集包含一组<i>属性值，</i>其中集合中不允许重复的值。</span> <span>此外，属性集中的每个值都是某个<i>类别</i>的成员<i>，</i>并且在该集合中允许任何特定类别中的最多一个值。</span> <span>对于属性集，值为<a href="../../../javax/print/attribute/Attribute.html" title="javax.print.attribute中的接口"><code>Attribute</code></a>对象，类别为<a href="../../../java/lang/Class.html" title="java.lang中的类"><code>类</code></a>对象。</span> <span>属性类别是该类属性的类层次结构根目录下的类（或接口）。</span> <span>请注意，属性对象的类别可能是属性对象的类的超类，而不是属性对象的类本身。</span> <span>属性对象的类别是通过调用确定<a href="../../../javax/print/attribute/Attribute.html#getCategory--"><code>getCategory()</code></a>在接口中定义的方法<a href="../../../javax/print/attribute/Attribute.html" title="javax.print.attribute中的接口"><code>Attribute</code></a> 。</span> </p>
|
||||
<p> <span>AttributeSet的接口类似于Java Collections API的java.util.Map接口的接口，但是它将接受的类型更具限制性，并将键和值组合到一个Attribute中。</span> </p>
|
||||
<p> <span>属性集在Print Service API的多个位置使用。</span> <span>在每个上下文中，只有某些种类的属性被允许出现在该属性集，如由该属性类实现加标签接口确定- <a href="../../../javax/print/attribute/DocAttribute.html" title="javax.print.attribute中的接口"><code>DocAttribute</code></a> ， <a href="../../../javax/print/attribute/PrintRequestAttribute.html" title="javax.print.attribute中的接口"><code>PrintRequestAttribute</code></a> ， <a href="../../../javax/print/attribute/PrintJobAttribute.html" title="javax.print.attribute中的接口"><code>PrintJobAttribute</code></a>和<a href="../../../javax/print/attribute/PrintServiceAttribute.html" title="javax.print.attribute中的接口"><code>PrintServiceAttribute</code></a> 。</span> <span>但是也有一些限制为仅包含四种属性的一个属性组四个特- <a href="../../../javax/print/attribute/DocAttributeSet.html" title="javax.print.attribute中的接口"><code>DocAttributeSet</code></a> ， <a href="../../../javax/print/attribute/PrintRequestAttributeSet.html" title="javax.print.attribute中的接口"><code>PrintRequestAttributeSet</code></a> ， <a href="../../../javax/print/attribute/PrintJobAttributeSet.html" title="javax.print.attribute中的接口"><code>PrintJobAttributeSet</code></a>和<a href="../../../javax/print/attribute/PrintServiceAttributeSet.html" title="javax.print.attribute中的接口"><code>PrintServiceAttributeSet</code></a> ，分别。</span> <span>请注意，许多属性类实现多个标记接口，因此可能会出现在多个上下文中。</span> </p>

<ul>

<li> <span>甲<a href="../../../javax/print/attribute/DocAttributeSet.html" title="javax.print.attribute中的接口"><code>DocAttributeSet</code></a> ，含有<a href="../../../javax/print/attribute/DocAttribute.html" title="javax.print.attribute中的接口"><code>DocAttribute</code>个</a> S，指定单个文档和所述打印作业设置的特性，以被应用到一个单独的文档。</span> <p></p></li>

<li> <span>一个<a href="../../../javax/print/attribute/PrintRequestAttributeSet.html" title="javax.print.attribute中的接口"><code>PrintRequestAttributeSet</code></a> ，含<a href="../../../javax/print/attribute/PrintRequestAttribute.html" title="javax.print.attribute中的接口"><code>PrintRequestAttribute</code>个</a> S，指定设置应用到整个打印作业，并在打印作业中所有文档。</span> <p></p></li>

<p> <span>在某些情况下，只允许客户端检查属性集的内容，但不允许更改它们（该集合是只读的）。</span> <span>在其他地方，允许客户端检查和更改属性集的内容（集合是读写）。</span> <span>对于只读属性集，调用mutating操作会引发UnmodifiableSetException。</span> </p>

<p> <span>Print Service API提供了一个接口AttributeSet的实现，类别为<a href="../../../javax/print/attribute/HashAttributeSet.html" title="javax.print.attribute中的类"><code>HashAttributeSet</code></a> 。</span> <span>客户端可以使用类别<a href="../../../javax/print/attribute/HashAttributeSet.html" title="javax.print.attribute中的类"><code>HashAttributeSet</code></a>或提供自己的接口AttributeSet的实现。</span> <span>打印服务API还提供：接口AttributeSet的子接口的实现-班<a href="../../../javax/print/attribute/HashDocAttributeSet.html" title="javax.print.attribute中的类"><code>HashDocAttributeSet</code></a> ， <a href="../../../javax/print/attribute/HashPrintRequestAttributeSet.html" title="javax.print.attribute中的类"><code>HashPrintRequestAttributeSet</code></a> ， <a href="../../../javax/print/attribute/HashPrintJobAttributeSet.html" title="javax.print.attribute中的类"><code>HashPrintJobAttributeSet</code></a>和<a href="../../../javax/print/attribute/HashPrintServiceAttributeSet.html" title="javax.print.attribute中的类"><code>HashPrintServiceAttributeSet</code></a> 。</span> </p>
