As a simplification, this is not needed I would say. We could just remove the owner var and constructor param, and leave only a simple toStringBase like this:
protected String toStringBase() {
return "owner='" + getClass().getSimpleName() + '\'' +
", type=" + type;
}
It would end up returning the simple name of the child class, which is what we want in the end.

maybe we could get rid of owner after all, and just have the calling class to print its name so that we could follow a more conventional toString(). Here's an example of how it might look like after getting rid of owner. Would this work?
ListOffsetsApplicationEvent{type=LIST_OFFSETS, future=java.util.concurrent.CompletableFuture@bdd2027[Not completed], timestampsToSearch={}, requireTimestamps=false}

Sure, the point was to avoid the duplicated info in the toString, result of including the class name in the base class and in the child implementations. See my previous comment related to this down below.

This would then change back to how it was if we agree on using the getClass().getSimpleName() in the toStringBase
| return getClass().getSimpleName() + " {" + | ||
| "timestampsToSearch=" + timestampsToSearch + ", " + | ||
| "requireTimestamps=" + requireTimestamps + '}'; | ||
| return "ListOffsetsApplicationEvent{" + |

Is it intentional to explicitly include "ListOffsetsApplicationEvent" here? it is in the "owner" section of the toStringBase too.

(Similar for all other events that are explicitly including the class name and then calling the toStringBase)

Apparently @kirktrue implemented those in his previous commit. So closing this. |

This is a follow up of #14386.
The goal of this PR is to refactor the toString method to reduce duplicated code.
