本文整理了Java中java.lang.Package.isSealed()方法的一些代码示例，展示了Package.isSealed()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。Package.isSealed()方法的具体详情如下：
包路径：java.lang.Package
类名称：Package
方法名：isSealed

Package.isSealed介绍

[英]Indicates whether this package is sealed.
[中]指示此包是否已密封。

代码示例

/**
 * {@inheritDoc}

public boolean isCompatibleTo(Package definedPackage) {
  if (sealBase == null) {
    return !definedPackage.isSealed();
  } else {
    return definedPackage.isSealed(sealBase);
  }
}
