XMLStreamReader介绍

[英]This interface is similar to javax.xml.stream.XMLStreamReader; but it does not forces dynamic allocation when parsing (its methods returns CharArray instances instead of String).

Except for the speed (faster) and its real-time characteristics the usage/behavior is about the same as its StAX counterpart.

The CharArray instances returned by this reader supports fast primitive conversions as illustrated below. [code] // Creates a new reader (potentially recycled). XMLInputFactory factory = OSGiServices.getXMLInputFactory(); XMLStreamReader reader = factory.createXMLStreamReader(inputStream); while (reader.getEventType() != XMLStreamConstants.END_DOCUMENT) { switch (reader.next()) { case XMLStreamConstants.START_ELEMENT: if (reader.getLocalName().equals("Time")) { // Reads primitive types (int) attributes directly (no memory allocation). time.hour = reader.getAttributeValue(null, "hour").toInt(); time.minute = reader.getAttributeValue(null, "minute").toInt(); time.second = reader.getAttributeValue(null, "second").toInt(); } ... break; } } reader.close(); // Close the reader (does not close underlying input stream). [/code]
[中]这个界面类似于javax.xml.stream.XMLStreamReader；但它在解析时不强制动态分配（它的方法返回CharArray实例而不是String）。
除了速度（更快）及其实时性特征外，使用/行为与StAX差不多。
该读取器返回的CharArray实例支持如下所示的快速原语转换。[code]//创建一个新的读卡器（可能回收）。XMLInputFactory工厂=OSGiServices。getXMLInputFactory（）；XMLStreamReader=工厂。createXMLStreamReader（inputStream）；while（reader.getEventType（）！=XMLStreamConstants。END_DOCUMENT）{switch（reader.next（））{case XMLStreamConstants.START_元素：if（reader.getLocalName（）.equals（“Time”）{//直接读取基本类型（int）属性（无内存分配）。Time.hour=reader.getAttributeValue（null，“hour”）.toInt（）；Time.minute=reader.getAttributeValue（null，“minute”）.toInt（）; 时间第二个=读卡器。getAttributeValue（空，“秒”）。toInt（）；}。。。中断；}读者close（）；//关闭读卡器（不关闭底层输入流）。[code]
