Extending functionality of Data class

[Roman Yankin]

Though this seems to be obvious, I want to make sure everyone agrees with me. In my assignment I have introduced a couple of public methods that are not referenced in DB interface. So is it legal to extend functionality of Data class by introducing public methods?

Hey,

yes i see no reason why one could not do this as long as the methods are related to the functionality of the Data class and not functionality which should be delegated to another class. What will these new methods do exactly?

Well those methods can be divided into two groups. The first group deals with records. For instance I've added wrapper methods that encapsulate calls to lock/unlock methods in combination with read/update/delete operation. The second group are those methods that deal with internal data cache - a map where all records are kept for performance reasons.
