Custom list implementation
Hello List,
Is possible to choose what List implementation is returned when
queryForList(...) is called.
For example, suppose I have my own list implementation that extends
ArrayList. Can I do the following
MyCustomList lst = (MyCustomList)queryForList("myQuery",
params);
Currently what I do is
MyCustomList lst = new MyCustomList(queryForList("myQuery",
params));
Thanks,
Paul

RE: Lazy Load is pre loading 1-1 relationships
Be careful with lazy loading 1-1 relationships where the lazy loaded
result could be null. A proxy object will be in its place.
e.g.
if ( foo.getBar() == null ) { // Bar is lazy loaded.
// Unreachable code

RE: Lazy Load is pre loading 1-1 relationships
I doubt my reply will answer your question, but this is mostly for
information purpose.
All final classes are never lazy loaded by iBATIS. This include any
primitive type, Strings and this like Integer, Double, etc...
This "bug" is probably due to the fact that cglib tries to extend the
class. If it is final, it must be loaded now.

I've been spending a fair amount of time on this now but I can't seem to

loading. The relationships that are 1-M seem to be fine, meaning that
they are not pre-loading, but any relationship that I have that is a 1-1

Is there anything I can do to prevent this from happening?

Subject: How to support read-only fields/paramters
(This may not be totally iBatis realated, I'm not sure. Feel free to
point me elsewhere)
Often when working with objects, you have fields that should never be
changed (e.g. an "id" field which is generated by the database). The
usual way (as I understand it) that you achieve this, is to specify the
parameter value in the objects constructor, and only provide a get()
method, with no corresponding set() method (or a final private one so
that it can't be over-ridden)
However, iBatis does not use the parmaterised constructor to build an
object. Instead, it uses the null constructor, and then calls the
individual set() methods - which have to be public for iBatis to be able
to call them. This means that anyone could call the set() method and
change the value.
There are two ways that I can see to achieve this:
1) Only allow the set() method to be called once. (Use some internal
boolean flag to see if it the set() method has been called before)
2) Somehow configure/change iBatis so that it would use the constructor
to set the request fields.
Anyone got any thoughts or comments on this ?
Thanks,

I changed the Ibatis class EnhancedLazyResultLoader.
1) I had to make an inner class Serializable. This involved making the
field that links to the jdbc connection transient. I then had to put my
application code into this class to set this transient field. Thats a
hack that you may want to improve on.
2) Changed the EnhancedLazyResultLoaderImpl.loadResult() method to only
create proxy objects for IBaseDomain results ( that are not abstract).
The reason for not lazy loading abstract classes is because the
instanceof does not work as expected when comparing to a concrete class.

Subject: iBatis Book - Lazy Loading Description
The new iBatis book describes lazy-loading as follows (pg 131).
"To use lazy loading, we need to edit the SqlMapConfig.xml file to
enable it by changing the lazyLoadingEnabled attribute to true in the
element. If you want to use the cglib enhanced version of lazy
loading, you will want to download it, add it to your application's
classpath, and change the enhancementEnabled attribute of the
element to true as well."
After setting up a sample similar to that in the book, I noticed that
lazy-loading only appears to work correctly if BOTH lazyLoadingEnabled
and enhancementEnabled are set to true. Running the following code
executes the selects as the objects are requested.
person = sqlMapper.queryForObject("Person.selectPerson"); // runs select
... from person
person.getAddress(); // runs select .. from address
person.getAddress().getState(); // runs select .. from state
Setting enhancementEnabled to false causes all of the select statements
to execute initially. Changing lazyLoadingEnabled to false doesn't
change the behavior.
person = sqlMapper.queryForObject("Person.selectPerson"); // runs all 3
select statements
person.getAddress();
person.getAddress().getState();
Is this correct behavior? If so, when would I benefit from
lazyLoadingEnabled = "true"?
I'm using iBatis version 2.3.0.677

RE: Lazy Loading
You need to set enhancementEnabled="true" and have cglib in you classpath.
That will cause ibatis to use EnhancedLazyResultLoader.
There is still some issues with 1:1 enhanced lazy loading.
1) If you use the tag to return 1:1 lazy loaded sub classes
then you will not be able to cast the returned object to the subclass. That's
because the proxy object returned is based on the method return type. I
changed EnhancedLazyResultLoader to not lazy load 1:1 abstract classes. This
reduced the effect of this issue.
2) If the lazy loaded object returns no results you would expect null to be
returned. Instead a proxy object is returned and calling methods on the proxy
object will return null. This was a major problem for me.
E.g. If ( foo.getBar() == null ) {
// Will never happen.
}
To get over this problem I used a custom ResultObjectFactory to add a method
interceptor which would check for the above scenario and return null if
required. I can post that code if needed. If you relationship is 1:1 this
will not be an issue by my relationships were 1 to 0 or 1
3) Its harder to debug cgi enhanced objects using GUI debuggers.

enhancementEnabled and lazyLoadingEnabled problem.
Title: enhancementEnabled and lazyLoadingEnabled problem.
I have set enhancementEnabled="true" and lazyLoadingEnabled="true" in the SqlMapConfig
A problem exists when the lazy loaded object is null. Using the enhancementEnabled="true" option causes enhanced lazy loaded object to be returned from a getter even if the lazy query returned no rows. Calling any method on the enhanced object causes a null pointer exception.
For example. There is a 1 to 0..1 relationship between Foo and Bar.
Class Foo {
private Bar bar;
...
}
// Now here is the test that fails if set enhancementEnabled="true"
Foo foo = (Foo)queryForObject("fooWithNullBar", null);
Bar bar = foo.getBar();
assertTrue(bar == null); // FAILS!!!
If enhancementEnabled="false" then the test work. Is this a bug or have I misunderstood enhancementEnabled what the flag does? I'm using version 2.2.0.636.

RE: Parameterised constructors
How do private setters work?
Could I set the 'foo' property using the result map below? Is there
anything I have to do to the jmv to allow it access to the private
field?
public class Foo {
private String
foo;
public String getFoo()
{
return
foo;
}
}
Thanks,

As a temporary alternative we do support private setters as of
2.2.0. Constructor injection is supported in the .NET
version. The two codebases are somewhat similar, so we could always check
on their approach to it. Clinton

I remember some folks asking about this, but no commitment to do
it. It would require quite a change to the way iBATIS processes result
sets. Translation: don't expect this anytime soon.
BTW, the Sun patterns web site has some information about an immutable
transfer object pattern here:
http://java.sun.com/blueprints/patterns/TransferObject.html
The basic idea is that you create an interface for the immutable part,
and a mutable static inner class for initializing. This does work with
iBATIS. But one warning - we used this pattern on my team for a while
and everyone (me included) HATED it. So we eventually went to simple
JavaBeans with getters AND setters.

RE: Two quick questions..
Title: Two quick questions.. I'll add to those questions 1) Be careful when updating cached data in a transactional environment. If you update a cached object, then calling a rollback will undo db changes but not changes to the object in memory. You should clone cached object before updating in this case. 2) If you set ibatis to flush the cache on a update it will not work correctly in a clustered environment. Only one instance in the cluster would have its cached flushed.

RE: ResultSet metadata
I've got a similar problem. I have a immutable Quantity object that takes two
arguments for its constructor. No of the Quantity properties can be populated
using setter methods. I would like to use a custom type handler to construct
the object. Doing reflection on the result set will not always work because as
there can be more that one Quantity objects per row.
Here is my idea how ibatis could be changed for this to work.
1) Allow multiple column names to be in the 'column' attribute of the result
tag. See below.
.
2) Add a method to give the TypeHandlerCallback access to the names of the
column.
e.g.
public interface TypeHandlerCallback {
public String[] getColumnNames();
}
This would allow reflection on the result set using the column names. I'm sure
there are more elegant ways to do this where ibatis would do the reflection.
I guess I can expect someone to implement this in the next few days :)

I'm writing a custom type handler and want to get access to the meta data for

identify the particular column in which I'm interested? There doesn't appear
to be a way to obtain the column's name from the ResultGetter and I'm reluctant
to use reflection to obtain this information... Any thoughts?
