Class DocTreePathScanner<R,P>

java.lang.Object

com.sun.source.util.DocTreeScanner<R,P>

com.sun.source.util.DocTreePathScanner<R,P>

类型参数:

R - 此访问者方法的返回类型。对于不需要返回结果的访问者，请使用Void。

P - 此访问者方法的附加参数的类型。对于不需要附加参数的访问者，请使用Void。

所有已实现的接口:

DocTreeVisitor<R,P>

       public class DocTreePathScanner<R,P> extends DocTreeScanner<R,P>
      

访问所有子树节点的DocTreeVisitor，并提供支持以维护父节点的路径。要访问特定类型的节点，只需覆盖相应的visitorXYZ方法。在您的方法内部，调用super.visitXYZ以访问后代节点。

自 JDK 版本:

1.8
