本文整理了Java中org.h2.value.Value.negate()方法的一些代码示例，展示了Value.negate()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。Value.negate()方法的具体详情如下：
包路径：org.h2.value.Value
类名称：Value
方法名：negate

Value.negate介绍

[英]Return -value if this value support arithmetic operations.
[中]Return-如果此值支持算术运算，则返回值。

@Override
public Value getValue(Session session) {
  Value v = condition.getValue(session);
  if (v == ValueNull.INSTANCE) {

  }
  return v.convertTo(Value.BOOLEAN).negate();
}
