Package de.xima.fc.common.data.table

Class AbstractHeaderTable<T>

java.lang.Object

de.xima.fc.common.data.table.AbstractHeaderTable<T>

Type Parameters:

T - The type of the cell values.

All Implemented Interfaces:

IHeaderTable<T>, Serializable, Iterable<IHeaderTable.ITableRowEntry<T>>

Direct Known Subclasses:

ImmutableListHeaderTable

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.

Since:

8.2.0
