[hibernate-issues] [Hibernate-JIRA] Commented: (BVAL-220) Offer stereotypes to skip validation on empty or null

[Peter Davis (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/BVAL-220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=42681#action_42681 ] 

Peter Davis commented on BVAL-220:
----------------------------------

Suggestion:

@ReportAsSingleViolation(shortCircuit=true) /* better name? */
@NotNull /* or @NotEmpty, or @Size(min=50)... */
@Constraint(validatedBy=MyValidator)
public @interface MyConstraint {}

Currently Hibernate Validator invokes MyValidator even if the value is null.  This is wasteful and pointless.  It also makes it hard to compose cheap vs. expensive validations.  I don't believe this is addressed by the recent "OR" composition type addition to HVAL.
