本文整理了Java中org.teiid.core.types.XMLType类的一些代码示例，展示了XMLType类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。XMLType类的具体详情如下：
包路径：org.teiid.core.types.XMLType
类名称：XMLType

XMLType介绍

[英]This class represents the SQLXML object along with the Streamable interface. NOTE that this representation of XML does not become unreadable after read operations.
[中]此类表示SQLXML对象以及可流化接口。请注意，这种XML表示形式在读操作后不会变得不可读。

代码示例

public static XMLType xmlPi(String name, String content) {
  int start = 0;
  char[] chars = content.toCharArray();
  while (start < chars.length && chars[start] == ' ') {
    start++;
  }
  XMLType result = new XMLType(new SQLXMLImpl("<?" + name + " " + content.substring(start) + "?>")); //$NON-NLS-1$ //$NON-NLS-2$ //$NON-NLS-3$
  result.setType(Type.PI);
  return result;
}
