Having recently looked at our Java UNO binding, it occurred to me that
another advantage of Java 7 would be that we could update our Java UNO base
classes to implement AutoCloseable, allowing try-with-resources to be used
to manage UNO reference counting precisely and delete unused objects as
soon as they go out of scope (just like the C++ binding does), instead of
the current finalize() methods which rely on the garbage collector and so
run much later if ever, or manually calling dispose() which needs to be
done in a finally block to be safe.
eg.
try (XPropertySet xCursorProps = (XPropertySet)
UnoRuntime.queryInterface(XPropertySet.class, mxDocCursor);) {
Object value = xCursorProps.getPropertyValue("CharWeight");
}
instead of the current:
XPropertySet xCursorProps = (XPropertySet)
UnoRuntime.queryInterface(XPropertySet.class, mxDocCursor);
try {
Object value = xCursorProps.getPropertyValue("CharWeight");
} finally {
xCursorProps.dispose();
}
for which try blocks would also need to nest for multiple objects, unlike
with try-with-resources.
