Type Parameters:

T - The type of the message that must be returned by this call.

Enclosing class:

KeyValueEntity<S>

public static interface KeyValueEntity.Effect<T>

An Effect is a description of what the runtime needs to do after the command is handled. You can think of it as a set of instructions you are passing to the runtime, which will process the instructions on your behalf.

Each component defines its own effects, which are a set of predefined operations that match the capabilities of that component.

a KeyValueEntity Effect can either:

• update the entity state and send a reply to the caller
• directly reply to the caller if the command is not requesting any state change
• rejected the command by returning an error
• instruct the runtime to delete the entity
