org.mmbase.datatypes
Class UniqueStringDataType

java.lang.Object
  org.mmbase.core.AbstractDescriptor
      org.mmbase.datatypes.BasicDataType<E>
          org.mmbase.datatypes.ComparableDataType<String>
              org.mmbase.datatypes.StringDataType
                  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.

Since:

MMBase-1.8.6
