org.gephi.data.attributes.api.AttributeTable
Table hosts columns and permits all manipulation on them. Columns can be appened with different level of details. The table maintains a map with column identifier and title (header) in order they can be retrieved efficiently.
Tracking added or removed columns can be performed by adding an {@link AttributeListener} to this table. @author Mathieu Bastian @author Martin Škurla @see AttributeColumn @see AttributeRow
