Interface ValueCommands<K,V>
- Type Parameters:
K
- the type of the keyV
- the type of the value
- All Superinterfaces:
RedisCommands
- All Known Implementing Classes:
BlockingStringCommandsImpl
Allows executing commands from the
string
group.
See the string command list for further information
about these commands.
This group can be used with value of type String
, or a type which will be automatically
serialized/deserialized with a codec.
NOTE: Instead of string
, this group is named value
to avoid the confusion with the
Java String type. Indeed, Redis strings can be strings, numbers, byte arrays...
