Class DefaultRedisScript<T>

java.lang.Object

org.springframework.data.redis.core.script.DefaultRedisScript<T>

Type Parameters:

T - The script result type. Should be one of Long, Boolean, List, or deserialized value type. Can be null if the script returns a throw-away status (i.e "OK")

All Implemented Interfaces:

InitializingBean, RedisScript<T>

public class DefaultRedisScript<T>
extends Object
implements RedisScript<T>, InitializingBean

Default implementation of RedisScript. Delegates to an underlying ScriptSource to retrieve script text and detect if script has been modified (and thus should have SHA1 re-calculated). This class is best used as a Singleton to avoid re-calculation of SHA1 on every script execution.
