的具体用法。这些代码示例主要来源于Github

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。Lookup.lookupResult()
方法的具体详情如下:
包路径:org.openide.util.Lookup
类名称:Lookup
方法名:lookupResult
[英]Find a result corresponding to a given class. Equivalent to calling #lookup(Lookup.Template) but slightly more convenient. Subclasses may override this method to produce the same semantics more efficiently.
[中]查找与给定类对应的结果。相当于调用#lookup(lookup.Template),但稍微方便一些。子类可以重写此方法以更有效地生成相同的语义。
