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>, AssignmentTestable

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.
