[hibernate-dev] [Bean Validation] @Pattern
I had a lot of demands for regexp support and since there is a need
for string matching in the built-in constraints...
http://opensource.atlassian.com/projects/hibernate/browse/HV-121
I replaced the bitwise guru flags approach with an enum
@Pattern( regexp = ".*", flags = { Pattern.Flag.CANON_EQ })
String name;
/**
* The annotated String must match the following regular expression.
* The regular expression follows the Java regular expression conventions
* see {@link java.util.regex.Pattern}.
*
* Accepts String.
