Class NanoIdBuilder

java.lang.Object
cloud.opencode.base.id.nanoid.NanoIdBuilder
public final class NanoIdBuilder extends Object
NanoID Generator Builder NanoID生成器构建器

Fluent builder for creating customized NanoIdGenerator instances.

用于创建自定义NanoIdGenerator实例的流式构建器。

Features | 主要功能:

  • Custom size configuration - 自定义长度配置
  • Custom alphabet selection - 自定义字母表选择
  • Random source configuration - 随机源配置

Usage Examples | 使用示例:

NanoIdGenerator gen = new NanoIdBuilder()
    .size(16)
    .alphabet(Alphabet.ALPHANUMERIC)
    .secureRandom()
    .build();

NanoIdGenerator customGen = new NanoIdBuilder()
    .size(8)
    .alphabet("0123456789")
    .build();

Security | 安全性:

  • Thread-safe: No (use before build) - 线程安全: 否（在build前使用）

Performance | 性能特性:

  • Time complexity: O(1) for build() and all setter methods - 时间复杂度: build() 及所有 setter 方法均为 O(1)
  • Space complexity: O(1) - stores only size, alphabet reference, and random source - 空间复杂度: O(1) - 仅存储长度、字母表引用和随机源
