All Implemented Interfaces:

Serializable, Comparable<ScriptOutputType>, java.lang.constant.Constable

public enum ScriptOutputType
extends Enum<ScriptOutputType>

A Lua script returns one of the following types:

• BOOLEAN boolean
• INTEGER 64-bit integer
• STATUS status string
• VALUE value
• MULTI of these types

Redis to Lua conversion table.

• Redis integer reply -> Lua number
• Redis bulk reply -> Lua string
• Redis multi bulk reply -> Lua table (may have other Redis data types nested)
• Redis status reply -> Lua table with a single ok field containing the status
• Redis error reply -> Lua table with a single err field containing the error
• Redis Nil bulk reply and Nil multi bulk reply -> Lua false boolean type

Lua to Redis conversion table.

• Lua number -> Redis integer reply (the number is converted into an integer)
• Lua string -> Redis bulk reply
• Lua table (array) -> Redis multi bulk reply (truncated to the first null inside the Lua array if any)
• Lua table with a single ok field -> Redis status reply
• Lua table with a single err field -> Redis error reply
• Lua boolean false -> Redis Nil bulk reply.
