Class BeanTableModel

java.lang.Object

javax.swing.table.AbstractTableModel

uk.ac.starlink.util.gui.BeanTableModel

All Implemented Interfaces:

Serializable, TableModel

public class BeanTableModel
extends AbstractTableModel

TableModel which displays beans. The table is constructed to display beans of a particular class, and each of its row displays one instance of this class. It has one column for each readable property. As usual, a bean is anything which has likely-looking getter methods, though by using the java.beans package any cleverer stuff held in BeanInfos will get used as well/instead. What a neat idea!

Constructor Detail

BeanTableModel

public BeanTableModel(Class<?> clazz)
               throws IntrospectionException

Constructs a new table model for displaying beans of a given class.

Parameters:

clazz - class of items which will be displayed in this table

Throws:

IntrospectionException

Method Detail

setData

public void setData(Object[] data)

Populates this model with items.

Parameters:

data - array of items, one for each row. This array's runtime type must match that for which this model was constructed (on pain of ClassCastException)

getData

public Object[] getData()

Returns the array of objects which this model displays, one per row. The runtime type of the returned array matches that of the bean class this model displays.

Returns:

table data

propertySorter

public Comparator<?> propertySorter(String propertyName)

Returns a sorter which can be used to sort rows of this table (data array elements).

Parameters:

propertyName - name of readable bean property to sort on

Returns:

a comparator that sorts on propertyName, or null if propertyName does not name a suitable property
