Second, given that this task class is a Runnable, the result of the array access needs to be assigned to the state field (and state needs to be used in an overriding toString method) to prevent DCE.

To make this method a little easier, I wrap the access to the variable in a second function that takes a configuration key name and a default value, as shown below.

The second method operates in the same fashion but employs two additional parameters to specify the record store's access restrictions.
