StarTable which displays beans. The table is constructed to display beans of a particular class, and each of its rows displays one instance of this class. It has a column for each readable property. As usual, a bean is anything which has likely-looking getter methods, though since this class uses the java.beans package any cleverer stuff held in BeanInfos will get used as well/instead.
Constructor Summary | |
BeanStarTable(Class clazz)
Constructs a new table which will hold beans which are all instances of a given class. |
Method Summary | |
Object |
getCell(long irow,
int icol)
The AbstractStarTable implementation of this method throws an UnsupportedOperationException, since unless otherwise provided there is no random access. |
int |
getColumnCount()
Returns the number of columns in this table. |
ColumnInfo |
getColumnInfo(int icol)
Returns the object describing the data in a given column. |
Object[] |
getData()
Returns the array of objects which this model displays, one per row. |
Object |
getProperty(Object bean,
int iprop)
Returns the value of a given indexed property on a given bean. |
long |
getRowCount()
The number of rows in this table. |
void |
setData(Object[] data)
Populates this model with items. |
