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

Lookup.lookupAll介绍

[英]Find all instances corresponding to a given class. Equivalent to calling #lookupResult and asking for Lookup.Result#allInstances but slightly more convenient. Subclasses may override this method to produce the same semantics more efficiently.

Example usage:

for (MyService svc : Lookup.getDefault().lookupAll(MyService.class)) { 
svc.useMe(); 
}

[中]查找与给定类对应的所有实例。相当于调用#lookupResult并请求查找。结果#所有仪器，但稍微方便一点。子类可以重写此方法以更有效地生成相同的语义。
用法示例：

for (MyService svc : Lookup.getDefault().lookupAll(MyService.class)) { 
svc.useMe(); 
}
