本文整理了Java中org.dataconservancy.model.dcs.support.Util.isNull()方法的一些代码示例，展示了Util.isNull()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。Util.isNull()方法的具体详情如下：
包路径：org.dataconservancy.model.dcs.support.Util
类名称：Util
方法名：isNull

Util.isNull介绍

[英]Returns true if o is null.
[中]如果o为[$2$]，则返回true。

代码示例

/**
 * Throws {@link IllegalArgumentException} if <code>o</code> is <code>null</code>.
 *
 * @param o an object
 * @return the object
 */
static public Object notNull(Object o) {
  final String msg = "Object must not be null";
  if (Util.isNull(o)) {
    throw new IllegalArgumentException(msg);
  }
  return o;
}

代码示例来源：origin: org.dataconservancy.model/dcs-model

/**
 * Returns true if <code>s</code> is empty or <code>null</code>.
 *
 * @param s a string
 * @return true if <code>s</code> is empty or <code>null</code>.
 */
public static boolean isEmptyOrNull(String s) {
  return isNull(s) || isEmpty(s);
}
