Method Detail

execute

default <T> reactor.core.publisher.Flux<T> execute(RedisScript<T> script)

Execute the given RedisScript

Parameters:

script - must not be null.

Returns:

the return value of the script or Flux.empty() if RedisScript.getResultType() is null, likely indicating a throw-away status reply (i.e. "OK")

execute

default <T> reactor.core.publisher.Flux<T> execute(RedisScript<T> script,
                                                   List<K> keys)

Execute the given RedisScript

Parameters:

script - must not be null.

keys - must not be null.

Returns:

the return value of the script or Flux.empty() if RedisScript.getResultType() is null, likely indicating a throw-away status reply (i.e. "OK")

execute

<T> reactor.core.publisher.Flux<T> execute(RedisScript<T> script,
                                           List<K> keys,
                                           List<?> args)

Executes the given RedisScript

Parameters:

script - The script to execute. Must not be null.

keys - Any keys that need to be passed to the script. Must not be null.

args - Any args that need to be passed to the script. Can be empty.

Returns:

The return value of the script or Flux.empty() if RedisScript.getResultType() is null, likely indicating a throw-away status reply (i.e. "OK")

execute

<T> reactor.core.publisher.Flux<T> execute(RedisScript<T> script,
                                           List<K> keys,
                                           List<?> args,
                                           RedisElementWriter<?> argsWriter,
                                           RedisElementReader<T> resultReader)

Executes the given RedisScript, using the provided RedisSerializers to serialize the script arguments and result.

Parameters:

script - The script to execute. must not be null.

keys - Any keys that need to be passed to the script

args - Any args that need to be passed to the script

argsWriter - The RedisElementWriter to use for serializing args. Must not be null.

resultReader - The RedisElementReader to use for serializing the script return value. Must not be null.

Returns:

The return value of the script or Flux.empty() if RedisScript.getResultType() is null, likely indicating a throw-away status reply (i.e. "OK")
