Interface TreeVisitor<T>

Type Parameters:
T - the node type | 节点类型
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface TreeVisitor<T>
Tree Visitor 树访问者

Visitor interface for tree traversal.

树遍历的访问者接口。

Features | 主要功能:

  • Functional visitor interface for tree traversal - 树遍历的函数式访问者接口
  • Depth-aware visiting - 深度感知的访问
  • Early termination support - 支持提前终止

Usage Examples | 使用示例:

// Simple visitor
TreeVisitor<MyNode> visitor = TreeVisitor.of(node -> process(node));

// Visitor with depth
TreeVisitor<MyNode> visitor = TreeVisitor.withDepth((node, depth) ->
    System.out.println("  ".repeat(depth) + node));

Security | 安全性:

  • Thread-safe: Implementation-dependent - 取决于实现
  • Null-safe: No (node must not be null) - 否（节点不能为null）
Since:
JDK 25, opencode-base-tree V1.0.0
