本文整理了Java中org.eclipse.core.runtime.Assert类的一些代码示例，展示了Assert类的具体用法。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。Assert类的具体详情如下：
包路径：org.eclipse.core.runtime.Assert
类名称：Assert

Assert介绍

[英]Assert is useful for for embedding runtime sanity checks in code. The predicate methods all test a condition and throw some type of unchecked exception if the condition does not hold.

Assertion failure exceptions, like most runtime exceptions, are thrown when something is misbehaving. Assertion failures are invariably unspecified behavior; consequently, clients should never rely on these being thrown (and certainly should not be catching them specifically).

This class can be used without OSGi running.

This class is not intended to be instantiated or sub-classed by clients.
[中]Assert对于在代码中嵌入运行时健全性检查非常有用。谓词方法都测试一个条件，如果条件不成立，则抛出某种类型的未检查异常。
与大多数运行时异常一样，断言失败异常是在出现错误时抛出的。断言失败总是未指定的行为；因此，客户永远不应该依赖于抛出的这些数据（当然也不应该专门捕捉它们）。
该类可以在不运行OSGi的情况下使用。
该类不打算由客户端实例化或子类。
