本文整理了Java中com.google.common.base.Predicate.apply()方法的一些代码示例，展示了Predicate.apply()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。Predicate.apply()方法的具体详情如下：
包路径：com.google.common.base.Predicate
类名称：Predicate
方法名：apply

Predicate.apply介绍

[英]Returns the result of applying this predicate to input (Java 8 users, see notes in the class documentation above). This method is generally expected, but not absolutely required, to have the following properties:

  • Its execution does not cause any observable side effects.
  • The computation is consistent with equals; that is, Objects#equal (a, b) implies that predicate.apply(a) ==.
    [中]返回将该谓词应用于输入的结果（Java 8用户，请参阅上面类文档中的注释）。该方法通常具有以下特性，但并非绝对必需：
    *它的执行不会造成任何明显的副作用。
    *计算结果与等式一致；也就是说，宾语#equal（a，b）意味着这个谓词。应用（a）=。
