public class DBSchemaView
extends javax.swing.JFrame
implements java.util.Observer

GUI displaying a database schema. View in MVC pattern, observes the model and displays the query results when updated. A new instance should be created for every new findServiceDataquery. Once a query is completed it removes itself from observing the model so that it is not affected by future queries.

Parameters:
model - The data model to observe
parent - The parent window of this frame
Method Detail

update

public void update(java.util.Observable observable,
                   java.lang.Object updatedObject)
Specified by:
update in interface java.util.Observer

displayResults

private void displayResults(DatabaseSchemaMetaData schema)
Parse the database schema element into a table. Run as a GUIThread so the GUI remains responsive (for the progress monitor).

Parameters:
schema - database schema

stopObserving

public void stopObserving()
Stops this view observing the model. Useful if there is an error elsewhere and we don't want this view to continue monitoring.

Parameters:
schema - database schema
Throws:
java.lang.Exception

showTables

protected void showTables(DatabaseSchemaMetaData schema)
Sorts the database schema information into a tables. Metadata for each database table is displayed on a tab. There is one table containing column names, types and primary keys and a table each for imported and exported keys.

Parameters:
schema - the database schema

makeKeyTable

protected javax.swing.JTable makeKeyTable(KeyMetaData[] keys)
Builds the table for imported or exported keys.

Parameters:
keys -
Returns:
JTable

displayResults
