Method Detail

stopCellEditing

public boolean stopCellEditing()

Specified by:

stopCellEditing in interface CellEditor

Overrides:

stopCellEditing in class DefaultCellEditor

isValid

protected boolean isValid()

Returns a boolean indicating whether the current text is valid for instantiating the expected Number type.

Returns:

true if text is valid, false otherwise.

getNumber

protected Number getNumber()
                    throws Exception

Returns the editor value as number. May fail for a variety of reasons, as it forces parsing of the current text as well as reflective construction of the target type.

Returns:

the editor value or null

Throws:

Exception - if creation of the expected type fails in some way.

hasStrictFormatter

protected boolean hasStrictFormatter()

Returns:

getTableCellEditorComponent

public Component getTableCellEditorComponent(JTable table,
                                             Object value,
                                             boolean isSelected,
                                             int row,
                                             int column)

Override and set the border back to normal in case there was an error previously

Specified by:

getTableCellEditorComponent in interface TableCellEditor

Overrides:

getTableCellEditorComponent in class DefaultCellEditor

getCellEditorValue

public Number getCellEditorValue()
                          throws IllegalStateException

Overridden to instantiate a Number of the expected type. Note that this may throw a IllegalStateException if invoked without querying for a valid value with stopCellEditing. This should not happen during normal usage.

Specified by:

getCellEditorValue in interface CellEditor

Overrides:

getCellEditorValue in class DefaultCellEditor

Throws:

IllegalStateException - if current value invalid

getComponent

public JFormattedTextField getComponent()

Convenience override with type cast.

Overrides:

getComponent in class DefaultCellEditor
