/**
* Replaces the superclassm method to read the state of this class.
* <p>
* Serialization is not one of the JDK's nicest topics. Normal serialization will
* initialise the superclass before the subclass. Sometimes however, this isn't
* what you want, as in this case the <code>put()</code> method on read can be
* affected by subclass state.
* <p>
* The solution adopted here is to deserialize the state data of this class in
* this protected method. This method must be called by the
* <code>readObject()</code> of the first java.io.Serializable subclass.
* <p>
* Subclasses may override if the subclass has a specific field that must be present
* before <code>put()</code> or <code>calculateThreshold()</code> will work correctly.
