Direct Known Subclasses:

MMObjectBuilder

public class MMTable

extends java.lang.Object

MMTable is the base abstraction of a cloud of objects stored in one database tabel, essentially a cloud of objects of the same type. It provides a starting point for MMObjectBuilder by defining a scope - the database table - and basic functionality to create the table and query properties such as its size. This class does not contain actual management of nodes (this is left to MMOBjectBuilder).
