Wildcard Type Implementation 通配符类型实现

Implementation of WildcardType for runtime type construction.

用于运行时类型构造的WildcardType实现。

Features | 主要功能:

  • WildcardType runtime construction - WildcardType运行时构造
  • Upper and lower bounds support - 上界和下界支持
  • Proper equals/hashCode/toString - 正确的equals/hashCode/toString

Usage Examples | 使用示例:

// ? extends Number
WildcardType upper = new WildcardTypeImpl(new Type[]{Number.class}, new Type[0]);

// ? super Integer
WildcardType lower = new WildcardTypeImpl(new Type[]{Object.class}, new Type[]{Integer.class});

Security | 安全性:

  • Thread-safe: Yes (immutable) - 线程安全: 是（不可变）
  • Null-safe: No (bounds arrays must be non-null) - 空值安全: 否（边界数组须非空）
Since:
JDK 25, opencode-base-reflect V1.0.0
