cloud.opencode.base.core.convert.Convert
public final class Convert extends Object
Unified Type Conversion Entry - Static methods for type conversion 统一类型转换入口 - 类型转换的静态方法

Provides convenient static methods for common type conversions using registered converters.

提供使用注册转换器的常用类型转换便捷静态方法。

Features | 主要功能:

  • Primitive conversions (toInt, toLong, toDouble, toBoolean) - 基本类型转换
  • String conversion (toStr) - 字符串转换
  • Date/Time conversion (toDate, toLocalDate, toLocalDateTime) - 日期时间转换
  • Array conversion (toArray) - 数组转换
  • Generic conversion (convert with TypeReference) - 泛型转换

Usage Examples | 使用示例:

// Basic type conversion - 基本类型转换
Integer num = Convert.toInt("123", 0);
Boolean b = Convert.toBool("true");

// Date conversion - 日期转换
LocalDate date = Convert.toLocalDate("2024-01-15");

Security | 安全性:

  • Thread-safe: Yes (uses thread-safe registry) - 线程安全: 是 (使用线程安全注册表)
  • Null-safe: Yes (returns default on null) - 空值安全: 是 (null 返回默认值)
Since:
JDK 25, opencode-base-core V1.0.0
