I think this is fine. While I don't know if I would ever use it (I
suspect I would) I think it fills a void.
I think the implementation that Geert suggested is perfect (except
that his POJO extends something, but I'm sure that is a typo).
Blergh, it is :-/
Did it too fast, it should be like this of course:
Traditional method
==================
public class Blog extends CmfValidation
{
private int mId = -1;
private Date mMoment = Calendar.getInstance().getTime();
private byte[] mImage = null;
private String mTitle = null;
private String mBody = null;
private boolean mDraft = false;
protected void activateValidation()
{
addConstraint(new ConstrainedBean()
.defaultOrder("moment", ConstrainedBean.DESC)
.defaultOrder("title"));
addConstraint(new CmfProperty("id")
.editable(false)
.identifier(true));
addConstraint(new CmfProperty("moment")
.listed(true)
.notNull(true));
addConstraint(new CmfProperty("image")
.listed(true)
.mimeType(MimeType.IMAGE_PNG)
.contentAttribute("width", 150)
.notNull(true)
.file(true));
addConstraint(new CmfProperty("title")
.listed(true)
.notNull(true)
.notEmpty(true)
.maxLength(100));
addConstraint(new CmfProperty("body")
.mimeType(MimeType.APPLICATION_XHTML)
.autoRetrieved(true)
.fragment(true)
.notNull(true)
.notEmpty(true));
addConstraint(new CmfProperty("draft")
.notNull(true)
.defaultValue(false));
}
// accessors omitted
}
True POJO method
================
public class Blog
{
private int mId = -1;
private Date mMoment = Calendar.getInstance().getTime();
private byte[] mImage = null;
private String mTitle = null;
private String mBody = null;
private boolean mDraft = false;
// accessors omitted
}
public class BlogMetaData extends CmfValidation
{

{
addConstraint(new ConstrainedBean()
.defaultOrder("moment", ConstrainedBean.DESC)
.defaultOrder("title"));
addConstraint(new CmfProperty("id")

addConstraint(new CmfProperty("moment")
