Package Summary  Overview Summary

class:DefaultTableModel [NONE]
  • All Implemented Interfaces:
    Serializable, TableModel 
    public class DefaultTableModel
extends AbstractTableModel
implements Serializable
    This is an implementation of TableModel that uses a Vector of Vectors to store the cell value objects.

    Warning:DefaultTableModel returns a column class of Object. When DefaultTableModel is used with a TableRowSorter this will result in extensive use of toString, which for non-String data types is expensive. If you use DefaultTableModel with a TableRowSorter you are strongly encouraged to override getColumnClass to return the appropriate type.

    Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans™ has been added to the java.beans package. Please see XMLEncoder.

method:getDataVector() [NONE]

method:setDataVector(java.util.Vector,java.util.Vector) [NONE]

  • setDataVector

    public void setDataVector​(Vector<? extends Vector> dataVector,
                          Vector<?> columnIdentifiers)
    Replaces the current dataVector instance variable with the new Vector of rows, dataVector. Each row is represented in dataVector as a Vector of Object values. columnIdentifiers are the names of the new columns. The first name in columnIdentifiers is mapped to column 0 in dataVector. Each row in dataVector is adjusted to match the number of columns in columnIdentifiers either by truncating the Vector if it is too long, or adding null values if it is too short.

    Note that passing in a null value for dataVector results in unspecified behavior, an possibly an exception.

    Parameters:
    dataVector - the new data vector
    columnIdentifiers - the names of the columns
    See Also:
    getDataVector()

method:setDataVector(java.lang.Object[][],java.lang.Object[]) [NONE]

  • setDataVector

    public void setDataVector​(Object[][] dataVector,
                          Object[] columnIdentifiers)
    Replaces the value in the dataVector instance variable with the values in the array dataVector. The first index in the Object[][] array is the row index and the second is the column index. columnIdentifiers are the names of the new columns.
    Parameters:
    dataVector - the new data vector
    columnIdentifiers - the names of the columns
    See Also:
    setDataVector(Vector, Vector)

method:newDataAvailable(javax.swing.event.TableModelEvent) [NONE]

  • newDataAvailable

    public void newDataAvailable​(TableModelEvent event)
    Equivalent to fireTableChanged.
    Parameters:

method:newRowsAdded(javax.swing.event.TableModelEvent) [NONE]

  • newRowsAdded

    public void newRowsAdded​(TableModelEvent e)
    Ensures that the new rows have the correct number of columns. This is accomplished by using the setSize method in Vector which truncates vectors which are too long, and appends nulls if they are too short. This method also sends out a tableChanged notification message to all the listeners.
    Parameters:
    e - this TableModelEvent describes where the rows were added. If null it assumes all the rows were newly added
