Rick Hillegas updated DERBY-4869:
---------------------------------

    Attachment: derby-4869-01-ac-rs-getObject.diff

Attaching derby-4869-01-ac-rs-getObject.diff. This adds new JDBC 4.1 methods to ResultSet. I added a test case for these methods to the JDBC 4.0 test of ResultSets. That test runs cleanly for me on Java 6. I haven't run the test on Java 7 yet because the Linux installers for JDK 7 don't work. But I will look for another platform to test-drive these changes on Java 7. I am running the full regression test suites now.

Adds the following new methods to Derby's JDBC 4.0 implementations of ResultSet:

    public  <T> T getObject( int columnIndex, Class<T> type ) throws SQLException;
    public  <T> T getObject( String columnName, Class<T> type ) throws SQLException;

The implementations simply switch on the Class type and forward calls to the appropriate pre-existing getters.

I added a test for these methods to the test for JDBC 4.0 ResultSets. To simplify the code, I wrapped the Derby ResultSets in a class which exposes the new methods. We may want to revisit this test after Java 7 goes GA and we are allowed to ship a derbyTesting.jar which is built with the Java 7 compiler.


Touches the following files:

---------

M      java/engine/org/apache/derby/impl/jdbc/EmbedResultSet40.java

Added new forwarding methods to the embedded ResultSet.

---------

M      java/client/org/apache/derby/client/am/ResultSet.java
M      java/client/org/apache/derby/client/net/NetResultSet40.java

Added new forwarding methods to the network ResultSet.

---------

M      java/testing/org/apache/derbyTesting/functionTests/tests/jdbc4/ResultSetTest.java

Added a test for the new ResultSet methods.
