Class Doubles

java.lang.Object
cloud.opencode.base.core.primitives.Doubles
public final class Doubles extends Object
Double Array Utility Class - Guava-style operations for double primitive arrays double 数组工具类 - Guava 风格的 double 原始类型数组操作

Provides comprehensive double array operations inspired by Guava Doubles.

提供 double 原始类型数组的操作方法，参考 Guava Doubles。

Features | 主要功能:

  • Byte conversion (toByteArray, fromByteArray) - 字节转换
  • Array operations (concat, contains, indexOf, lastIndexOf) - 数组操作
  • Min/Max (min, max, constrainToRange) - 最值和范围
  • Collection conversion (asList, toArray) - 集合转换
  • Array manipulation (reverse, rotate, sortDescending) - 数组操作
  • Validation (isFinite) - 验证
  • String operations (join, tryParse) - 字符串操作

Usage Examples | 使用示例:

// Array operations - 数组操作
double[] merged = Doubles.concat(arr1, arr2);
int idx = Doubles.indexOf(arr, 3.14);
double min = Doubles.min(1.0, 2.0, 3.0);

Security | 安全性:

  • Thread-safe: Yes (stateless) - 线程安全: 是 (无状态)
  • Null-safe: Partially (throws on null array) - 空值安全: 部分 (null 数组抛异常)
Since:
JDK 25, opencode-base-core V1.0.0
