abstract class BehaviorSignalInterceptor[Inner] extends BehaviorInterceptor[Inner, Inner]
A behavior interceptor allows for intercepting signals reception and perform arbitrary logic - transform, filter, send to a side channel etc.
The BehaviorSignalInterceptor
API is considered a low level tool for building other features and
shouldn't be used for "normal" application logic. Several built-in intercepting behaviors
are provided through factories in the respective Behaviors
.
If the interceptor does keep mutable state care must be taken to create a new instance from
the factory function of Behaviors.intercept
so that a new instance is created per spawned
actor rather than shared among actor instance.
- Inner
The inner message type - the type of message the wrapped behavior accepts

(Since version 2.12.16) Use

instead ofvalue.formatted(formatString)
, or use thef""
string interpolator. In Java 15 and later,formatted
resolves to the new method in String which has reversed parameters.
