getDataList

public java.util.List getDataList()
Returns the List of Lists that contains the table's data values. The lists contained in the outer list are each a single row of values. In other words, to get to the cell at row 1, column 5:

Replaces the current dataList instance variable with the new List of rows, newData. columnNames are the names of the new columns. The first name in columnNames is mapped to column 0 in newData. Each row in newData is adjusted to match the number of columns in columnNames either by truncating the List if it is too long, or adding null values if it is too short.

Parameters:
newData - the new data list
columnNames - the names of the columns
See Also:

Parameters:
newData - the new data list
columnNames - the names of the columns
See Also:
setDataList(List, List)

Parameters:
event - this TableModelEvent describes where the rows were added. If null it assumes all the rows were newly added
See Also:
getDataList()

rowsRemoved

public void rowsRemoved(javax.swing.event.TableModelEvent event)
Equivalent to fireTableChanged.

If the number of newIdentifiers is less than the current number of columns, all the extra columns at the end of a row are discarded.

Parameters:
newIdentifiers - list of column identifiers. If null, set the model to zero columns
See Also:
setNumRows(int)

setColumnIdentifiers

public void setColumnIdentifiers(java.lang.Object[] newIdentifiers)
