public abstract class AbstractHeaderTable<T> extends Object implements IHeaderTable<T>, Serializable
Abstract implementation of IHeaderTable. Implements all methods that can be derived from other methods. You only need to implement IHeaderTable.columnNames() and IHeaderTable.rows(). You should also implement columnToIndex(String) and hasColumn(String) for performance reasons. All other methods cannot are final and cannot be overridden.
