Class CompareCondition

java.lang.Object

org.springframework.data.redis.connection.CompareCondition

public class CompareCondition
extends Object

Comparison-based condition for conditional Redis operations such as DELEX and SET. CompareCondition objects specify how to compare the existing value with an expected value, supporting both direct value comparison and digest-based comparison for efficient verification of large values.
