当成员为最终成员时,将新元素插入到 Trie

问题描述

我需要帮助来实现将新子项和兄弟项添加到 Trie 的插入方法。我看到了很多解决方案。但是,我的问题是不同的,因为类内部的类成员是最终的,所以当我遍历树时我无法引用下一个元素。我在互联网上搜索了很多,但似乎找不到任何帮助。我已经为此苦苦挣扎了两天。我将在下面分享我的代码

以下是我尝试过的所有插入方法

public class TrieChildren extends AbstractTrieChildren {
    public TrieChildren(char c,AbstractTrie t,AbstractTrieChildren o) {
        super(c,t,o);
    }

    @Override
    public AbstractTrieChildren insertSorted(char character,AbstractTrie child) {

        AbstractTrieChildren current = this;
        AbstractTrieChildren newEntry = new TrieChildren(character,child,null);

        if (current.child == null) {
            current = newEntry;
        }


        while (current != null) {


            if (current.sibling == null) {

                current = newEntry;

            }
            current = current.sibling;


        }


        return current;


    }

正如您在下面的代码中看到的那样,兄弟成员等成员是最终成员。

public abstract class AbstractTrieChildren implements Iterable<AbstractTrieChildren> {
    /**
     * The label of the outgoing edge.
     */
    protected final char character;
    /**
     * The target of the outgoing edge.
     */
    protected final AbstractTrie child;
    /**
     * The reference to the next sibling or {@code null} if none.
     */
    protected final AbstractTrieChildren sibling;

    public AbstractTrieChildren(char character,AbstractTrie child,AbstractTrieChildren sibling) {
        this.character = character;
        this.child = child;
        this.sibling = sibling;
    }

    /**
     * Adds a new labelled edge ({@link #character},{@link #child}) to the <b>sorted</b> traversable linked list of siblings iff there is no such edge.
     * If an entry already exists,then this method leaves the list unchanged.
     *
     * @param character the label of the possibly new labelled edge to insert
     * @param child     the target trie of the possibly new labelled edge to insert
     * @return the new head (left-most node) of the <b>sorted</b> traversable linked sibling list
     */
    public abstract AbstractTrieChildren insertSorted(char character,AbstractTrie child);
}

任何帮助将不胜感激。也许我错过了一些愚蠢的东西
