Class AbstractCompositeType
java.lang.Object
org.apache.cassandra.db.marshal.AbstractType<java.nio.ByteBuffer>
org.apache.cassandra.db.marshal.AbstractCompositeType
- All Implemented Interfaces:
- java.util.Comparator<java.nio.ByteBuffer>
- Direct Known Subclasses:
- CompositeType, DynamicCompositeType
public abstract class AbstractCompositeType
- extends AbstractType<java.nio.ByteBuffer>
A class avoiding class duplication between CompositeType and
DynamicCompositeType.
Those two differs only in that for DynamicCompositeType, the comparators
are in the encoded column name at the front of each component.
