Class AbstractType

java.lang.Object
  org.apache.cassandra.db.marshal.AbstractType

All Implemented Interfaces:

java.util.Comparator<byte[]>

Direct Known Subclasses:

BytesType, LexicalUUIDType, LongType, TimeUUIDType, UTF8Type

public abstract class AbstractType
extends java.lang.Object
implements java.util.Comparator<byte[]>

Specifies a Comparator for a specific type of byte[]. Note that empty byte[] are used to represent "start at the beginning" or "stop at the end" arguments to get_slice, so the Comparator should always handle those values even if they normally do not represent a valid byte[] for the type being compared.
