Class UniqueStringDataType

java.lang.Object
  extended by org.mmbase.core.AbstractDescriptor
      extended by org.mmbase.datatypes.BasicDataType<E>
          extended by org.mmbase.datatypes.ComparableDataType<String>
              extended by org.mmbase.datatypes.StringDataType
                  extended by org.mmbase.datatypes.UniqueStringDataType
All Implemented Interfaces:
Serializable, Cloneable, Comparable<DataType<String>>, Descriptor, DataType<String>, LengthDataType<String>, PublicCloneable<AbstractDescriptor>

public class UniqueStringDataType
extends StringDataType

Like StringDataType, but with an alternative implementation for the default value, namely, ensuring that it is unique already.
