cloud.opencode.base.core.retry.BackoffStrategy.ExponentialWithJitter
Record Components:
initialDelay - the initial delay - 初始延迟
multiplier - the multiplier (must be >= 1.0) - 乘数(必须 >= 1.0)
jitterFactor - jitter factor in [0.0, 1.0] - 抖动因子,范围 [0.0, 1.0]
All Implemented Interfaces:
BackoffStrategy
Enclosing interface:
BackoffStrategy

public static record BackoffStrategy.ExponentialWithJitter(Duration initialDelay, double multiplier, double jitterFactor) extends Record implements BackoffStrategy
Exponential backoff with jitter - adds randomness to prevent thundering herd. 带抖动的指数退避 - 添加随机性以防止惊群效应。

  • Constructor Details

    • ExponentialWithJitter

      public ExponentialWithJitter(Duration initialDelay, double multiplier, double jitterFactor)
      Creates an instance of a ExponentialWithJitter record class.
      Parameters:
      initialDelay - the value for the initialDelay record component
      multiplier - the value for the multiplier record component
      jitterFactor - the value for the jitterFactor record component
  • Method Details

    • delay

      public Duration delay(int attempt)
      Description copied from interface: BackoffStrategy
      Calculate the delay for the given attempt number. 计算给定重试次数的延迟。
      Specified by:
      delay in interface BackoffStrategy
      Parameters:
      attempt - attempt number, starting from 1 - 重试次数,从1开始
      Returns:
      the delay duration - 延迟时长
    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.
      Specified by:
      toString in class Record
      Returns:
      a string representation of this object
    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object
    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. Reference components are compared with Objects::equals(Object,Object); primitive components are compared with the compare method from their corresponding wrapper classes.
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
      true if this object is the same as the o argument; false otherwise.
    • initialDelay

      public Duration initialDelay()
      Returns the value of the initialDelay record component.
      Returns:
      the value of the initialDelay record component
    • multiplier

      public double multiplier()
      Returns the value of the multiplier record component.
      Returns:
      the value of the multiplier record component
    • jitterFactor

      public double jitterFactor()
      Returns the value of the jitterFactor record component.
      Returns:
      the value of the jitterFactor record component
