Type Parameters:
T - The Model object type
S - the type of the sort property
All Implemented Interfaces:
Serializable, ICellPopulator<T>, IExportableColumn<T,S>, IColumn<T,S>, IStyledColumn<T,S>, IDetachable, IClusterable

public class LambdaColumn<T,S> extends AbstractColumn<T,S> implements IExportableColumn<T,S>
An implementation of column that adds a label to the cell whose model is determined by the provided SerializableFunction that is evaluated against the current row's model object

Example for a table of Contacts:

 columns[0] = new LambdaColumn(new Model<String>("First Name"), Contact::getFirstName);
The above will attach a label to the cell which calls #getFirstName() for each displayed contact.
