Field Detail

ColorColumnRenderer

private DBClassifierEditor.ColorRenderer ColorColumnRenderer

An instance of the color renderer that is used to render the third column in the table with a suitable colored label.

ColorColumnEditor

private DBClassifierEditor.ColorEditor ColorColumnEditor

An instance of the color renderer that is used to render the third column in the table with a suitable colored label.

table

private javax.swing.JTable table

The JTable with the list of DB classifiers that are being currently edited by the user.

tableData

private javax.swing.table.DefaultTableModel tableData

This instance variable contains the mutable data model that contains the actual classifier data displayed in the table.

toolbar

private final javax.swing.JToolBar toolbar

The tool bar that contains the various buttons/tools with with the classifier list can be edited and modified.

mainFrame

private final MainFrame mainFrame

Convenient reference to the main frame class that contains this dialog box. This value is set in the constructor and is never changed. The main frame reference is primarily used to handle help requests.

A conventional message to be displayed to the user prior to canceling out of this dialog.

CHECK_MSG

private java.lang.String CHECK_MSG

A String.format() style message to be displayed to the user while prompting to enter data string for validating a given regular expression. The actual regular expression is substituted by the testRegExp() method.

CHECK_RESULT_MSG

private java.lang.String CHECK_RESULT_MSG

A String.format() style message to be displayed to the user after validating a regular expression against a data string entered by the user. The actual regular expression and data string is substituted by the testRegExp() method.

Constructor Detail

DBClassifierEditor

protected DBClassifierEditor(MainFrame parent)

The constructor. The constructor initializes the base class and then creates the various controls for editing the current list of database classifiers associated with this work space.

Parameters:

parent - The parent window to which this editor dialog logically belongs.

Method Detail

createTools

private void createTools()

Helper method to configure and setup various tools in the tool bar. This method was introduced to streamline the code better and cut down the code clutter in the constructor.

createTable

private void createTable()

Helper method to configure and setup various columns in the DB classifier list table. This method was introduced to streamline the code better and cut down the code clutter in the constructor.

setTableData

private void setTableData()

Helper method to copy data from workspace into table model. This is a helper method that is used to copy the data from the in-memory work space data structures into the table model to be displayed in the JTable.

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent e)

Specified by:

actionPerformed in interface java.awt.event.ActionListener

testRegExp

private void testRegExp()

Method to check the working status of a DB classifier. This method is invoked whenever the user clicks on the tool bar button to validate a classifier entry. This method first prompts the user to enter the data string to be matched with the regular expression. It then attempts to match the data string and provides the result back to the user.

checkAndClose

private void checkAndClose()

Helper method to check and close the dialog. This method is a helper method that is called from a couple of different places to cross check with the user before abandoning edits and exiting.

applyClassifiers

private void applyClassifiers(boolean closeDialog)

Helper method to validate regular expressions and apply them to the work space.

Parameters:

closeDialog - If this flag is true, then this method also hides and disposes the dialog.

valueChanged

public void valueChanged(javax.swing.event.ListSelectionEvent event)

Method intercepts table row selection notifications to enable/disable tool bar buttons.

Specified by:

valueChanged in interface javax.swing.event.ListSelectionListener

Specified by:

editingCanceled in interface javax.swing.event.CellEditorListener

editingStopped

public void editingStopped(javax.swing.event.ChangeEvent event)

Specified by:

editingStopped in interface javax.swing.event.CellEditorListener
