    • Method Detail

      • stopCellEditing

        public boolean stopCellEditing()
        Specified by:
        stopCellEditing in interface javax.swing.CellEditor
        Overrides:
        stopCellEditing in class javax.swing.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 java.lang.Number getNumber()
                              throws java.lang.Exception

        Returns:
        the editor value or null
        Throws:
        java.lang.Exception - if creation of the expected type fails in some way.

        Overrides:
        getCellEditorValue in class javax.swing.DefaultCellEditor
