Package org.springframework.data.redis.core

Interface ReactiveRedisCallback<T>

Type Parameters:

T -

public interface ReactiveRedisCallback<T>

Generic callback interface for code that operates on a low-level ReactiveRedisConnection. Allows to execute any number of operations on a single ReactiveRedisConnection, using any type and number of commands.

This is particularly useful for delegating to existing data access code that expects a ReactiveRedisConnection to work on. For newly written code, it is strongly recommended to use ReactiveRedisOperations's more specific operations.
