### Create a Session Dependency { #create-a-session-dependency }

A **`Session`** is what stores the **objects in memory** and keeps track of any changes needed in the data, then it **uses the `engine`** to communicate with the database.

    }
    size = 0;
  }

  @Override
  @J2ktIncompatible // Incompatible return type change. Use inherited (unoptimized) implementation
  public Object[] toArray() {
    Object[] copyTo = new Object[size];
    arraycopy(queue, 0, copyTo, 0, size);
    return copyTo;
  }

`objectSelector` is evaluated the oldObject and newObject that would be sent to the webhook, and is considered to match if either object matches the selector. A null object (oldObject in the case of create, or newObject in the case of delete) or an object that cannot have labels (like a DeploymentRollback or a PodProxyOptions object) is not considered to match. Use the object selector only if the webhook is opt-in, because end users may skip the admission webhook by setting the labels. ([#78505](htt...
