org.apache.cassandra.db.marshal
Class CollectionType<T>
java.lang.Object
org.apache.cassandra.db.marshal.AbstractType<T>
org.apache.cassandra.db.marshal.CollectionType<T>
- All Implemented Interfaces:
- java.util.Comparator<java.nio.ByteBuffer>
- Direct Known Subclasses:
- ListType, MapType, SetType
public abstract class CollectionType<T>
- extends AbstractType<T>
The abstract validator that is the base for maps, sets and lists.
Please note that this comparator shouldn't be used "manually" (through thrift for instance).

- Description copied from class:
AbstractType
- This must be overriden by subclasses if necessary so that for any
AbstractType, this == TypeParser.parse(toString()).
Note that for backwards compatibility this includes the full classname.
For CQL purposes the short name is fine.
- Overrides:
