创建自定义检查样式

我还有另一个关于如何安装和运行自定义 checkstyle 的 StackOverflow 问题。我已经学会了如何做到这一点，我将很快用详细说明更新该答案。现在我在定制支票时遇到了麻烦。下面是我的代码。问题是我希望将完全限定的包视为字符串（例如 com.amir.foo） - 但当我运行 getText() 或只是 toString()，我得到一些模糊的结果（[checkstyle] 包设置为：注释）。有谁知道如何使用它来达到预期的结果？

import com.puppycrawl.tools.checkstyle.api.*;

public class MyCheck extends Check
{

    FullIdent packageDeclaration;

    public int[] getDefaultTokens() {
        return new int[]{TokenTypes.PACKAGE_DEF};
    }

    public void visitToken(DetailAST ast)
    {

        switch(ast.getType()) {
            case TokenTypes.PACKAGE_DEF:
                System.out.println("got package!");
                visitPackage(ast);
                break;
            default:
                System.out.println("naughty!");
        }

    }

    private void visitPackage(DetailAST pack) {
        packageDeclaration = FullIdent.createFullIdentBelow(pack);
        System.out.println("package set to : " +packageDeclaration);
    }
}

I have another StackOverflow question on how to install and run a custom checkstyle. I've learned how to do this, and I will update that answer shortly with detailed instructions. Now I am having trouble customizing my check. Below is my code. The problem is I would like to see the fully qualified package as a string (e.g com.amir.foo) - but instead when I run getText() or just toString(), I get some obscure result ([checkstyle] package set to : ANNOTATIONS). Does anyone know how to work with this to achieve the desired results?

import com.puppycrawl.tools.checkstyle.api.*;

public class MyCheck extends Check
{

    FullIdent packageDeclaration;

    public int[] getDefaultTokens() {
        return new int[]{TokenTypes.PACKAGE_DEF};
    }

    public void visitToken(DetailAST ast)
    {

        switch(ast.getType()) {
            case TokenTypes.PACKAGE_DEF:
                System.out.println("got package!");
                visitPackage(ast);
                break;
            default:
                System.out.println("naughty!");
        }

    }

    private void visitPackage(DetailAST pack) {
        packageDeclaration = FullIdent.createFullIdentBelow(pack);
        System.out.println("package set to : " +packageDeclaration);
    }
}

您要查找的是用于检查包名称的，您应该使用类似于以下的代码：

@Override
public void visitToken(DetailAST aAST)
{
    final DetailAST nameAST = aAST.getLastChild().getPreviousSibling();
    final FullIdent full = FullIdent.createFullIdent(nameAST);
    final String package = full.getText();


    // do some fancy stuff with package name
}

What your looking for is used by the check for package names, you should use a code similar to the following:

@Override
public void visitToken(DetailAST aAST)
{
    final DetailAST nameAST = aAST.getLastChild().getPreviousSibling();
    final FullIdent full = FullIdent.createFullIdent(nameAST);
    final String package = full.getText();


    // do some fancy stuff with package name
}

For more details please refer to the source code of PackageNameCheck:
