[hibernate-issues] [Hibernate-JIRA] Commented: (HV-274) Write a programmatic mapping API for constraint declarations

[Emmanuel Bernard (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HV-274?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=37133#action_37133 ] 

Emmanuel Bernard commented on HV-274:
-------------------------------------

Ah that's interesting
(exploring here)

{code}
Size size = config.createConstraintExplorer(Size.class);
config
    .type( ShoppingCart.class )
    .onField("items")
    .addConstraint( Size.class )
      .message("Youhou!")
      .param( size.min(), 34)
      .param( size.max(), 100);

T param(U first, U second);
{code}

It's not as readable as the generics approach nor the hardcoded one but it goes a long way, is much simpler to set up than the generics approach and does not force people to write their ConstraintDescriptor.

Question:
 - how to deal with annotations accepting annotations as parameters
