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

ImmutableMap.of介绍

[英]Returns the empty map. This map behaves and performs comparably to Collections#emptyMap, and is preferable mainly for consistency and maintainability of your code.
[中]返回空映射。此映射的行为和性能与集合#emptyMap相当，主要是为了代码的一致性和可维护性。
