Assert.isNotNull介绍

[英]Asserts that the given object is not null. If this is not the case, some kind of unchecked exception is thrown.

As a general rule, parameters passed to API methods must not be null unless explicitly allowed in the method's specification. Similarly, results returned from API methods are never null unless explicitly allowed in the method's specification. Implementations are encouraged to make regular use of Assert.isNotNull to ensure that null parameters are detected as early as possible.
[中]断言给定对象不是null。如果不是这样，则会引发某种未经检查的异常。
作为一般规则，传递给API方法的参数不得为null，除非方法规范中明确允许。类似地，从API方法返回的结果永远不会是null，除非方法规范中明确允许。鼓励实施定期使用Assert.isNotNull，以确保尽早检测null参数。
