Record Class BinaryOpNode

java.lang.Object
java.lang.Record
cloud.opencode.base.expression.ast.BinaryOpNode
Record Components:
operator - the operator | 运算符
left - the left operand | 左操作数
right - the right operand | 右操作数
All Implemented Interfaces:
Node
public record BinaryOpNode(String operator, Node left, Node right) extends Record implements Node
Binary Operation Node 二元运算节点

Represents binary operations: arithmetic, comparison, logical.

表示二元运算：算术、比较、逻辑。

Features | 主要功能:

  • Arithmetic: +, -, *, /, %, ** - 算术运算
  • Comparison: ==, !=, >, >=, <, <= - 比较运算
  • Logical: &&, || with short-circuit evaluation - 逻辑运算，支持短路求值
  • Pattern matching: matches, instanceof - 模式匹配
  • String concatenation via + operator - 通过+运算符进行字符串连接

Usage Examples | 使用示例:

Node left = LiteralNode.of(10);
Node right = LiteralNode.of(3);
Node add = BinaryOpNode.of(left, "+", right);
Object result = add.evaluate(ctx);  // 13

Security | 安全性:

  • Thread-safe: Yes, immutable record - 线程安全: 是，不可变记录
  • Null-safe: No, null operands require non-null - 空值安全: 否，操作数要求非空
  • ReDoS protection: regex matching has timeout and length limits - ReDoS防护: 正则匹配有超时和长度限制
Since:
JDK 25, opencode-base-expression V1.0.0

      Description copied from interface: Node
      Get string representation for debugging 获取用于调试的字符串表示
      Specified by:
      toExpressionString in interface Node
      Returns:
      the string representation | 字符串表示

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object

      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.

      Returns:
      the value of the operator record component

    • left

      public Node left()
      Returns the value of the left record component.
      Returns:
      the value of the left record component

    • right

      public Node right()
      Returns the value of the right record component.
      Returns:
      the value of the right record component
