Annotation Interface NotEmpty

@Retention(RUNTIME) @Target(FIELD) public @interface NotEmpty
Validates that a field is not null and not empty.

Supports CharSequence (empty when length() == 0), Collection and Map (empty when isEmpty()), and arrays (empty when their length is zero). A null value always fails this constraint. Any other non-null type whose emptiness cannot be measured is also treated as invalid.
