Class DomUtil
java.lang.Object
cloud.opencode.base.xml.dom.DomUtil
DOM Utility Class - Utility methods for DOM manipulation
DOM 工具类 - DOM 操作的工具方法
This class provides static utility methods for common DOM operations including serialization, conversion, and node manipulation.
此类提供用于常见 DOM 操作的静态工具方法,包括序列化、转换和节点操作。
Features | 主要功能:
- Document/Node to String conversion - 文档/节点转字符串
- Element to Map conversion - 元素转 Map
- Text type conversion - 文本类型转换
- Node cloning and manipulation - 节点克隆和操作
Usage Examples | 使用示例:
// Convert document to string
String xml = DomUtil.toString(document, 4);
// Convert element to map
Map<String, String> map = DomUtil.toMap(element);
// Get text content with type conversion
int value = DomUtil.getInt(element, "count", 0);
Security | 安全性:
- Thread-safe: Yes (stateless utility) - 线程安全: 是(无状态工具)
- Null-safe: No (throws on null document/node) - 空值安全: 否(null 文档/节点抛异常)
Performance | 性能特性:
- Time complexity: O(n) for elementToMap/toMap (recursive traversal of all nodes, depth-limited to 1000); O(c) for getChildElements where c=child count; O(1) for scalar getters - 时间复杂度: elementToMap/toMap 为 O(n)(递归遍历所有节点,深度限制为 1000);getChildElements 为 O(c),c 为子元素数;标量获取器为 O(1)
- Space complexity: O(n) for map conversions; O(1) for scalar operations - 空间复杂度: map 转换为 O(n);标量操作为 O(1)
- Since:
- JDK 25, opencode-base-xml V1.0.0
