Constructor Detail

DBTest

public DBTest(String dbName,
              String fileName,
              String tableName)
       throws ClassNotFoundException

Constructs a new DBTest object.

This object is constructed and used only by the main(String[]) method of this class.

Parameters:

dbName - a String identifying the class implementing the com.opmath.util.db.DB interface.

fileName - a String identifying the name of the database file used for the test (the path is hard coded).

tableName - a String identifying the database table used for the test.

Method Detail

appendRow

protected void appendRow(String id,
                         String state)
                  throws SQLException

Appends a row of test data to the current table.

Parameters:

id - a String carrying data for the ID field of the table.

id - a String carrying data for the STATE field of the table.

Throws:

SQLException - if the database access fails.

Since:

J2SE 1.3

getRows

protected ResultSet getRows()
                     throws SQLException

Returns a ResultSet object that contains all of the data in the current table.

WARNING: getRows() creates a new ResultSet object, but does not close it. The caller of getRows() must therefore close the object returned by this method (with. eg. rs.close()) before getRows() can be called again. If this is not done, then getRows() may throw an exception, depending on the database driver class being tested.

Returns:

A ResultSet carrying data from a SELECT * FROM query.

Throws:

SQLException - if the database access fails.

Since:

J2SE 1.3

main

public static void main(String[] args)

The test application for classes implementing the DB implementation.

Refer to the source code of this application to see what's going on.

Parameters:

String[] - the String command line arguments for the application: arg[0] is the name of the implementing class; arg[1] is the name of the database file or directory (the path is hard wired); arg[2] is the name of the table.
