Enum Class CassandraPersistentPropertyComparator
java.lang.Object
java.lang.Enum<CassandraPersistentPropertyComparator>
org.springframework.data.cassandra.core.mapping.CassandraPersistentPropertyComparator
- All Implemented Interfaces:
Serializable
,Comparable<CassandraPersistentPropertyComparator>
,Constable
,Comparator<CassandraPersistentProperty>
public enum CassandraPersistentPropertyComparator
extends Enum<CassandraPersistentPropertyComparator>
implements Comparator<CassandraPersistentProperty>
Comparator
implementation that orders CassandraPersistentProperty
instances.
Composite primary key properties and primary key properties sort before non-primary key properties. Ordering rules:
- Composite primary keys first (equal if both
CassandraPersistentProperty
are a composite primary key) - Primary key columns (see
CassandraPrimaryKeyColumnAnnotationComparator
, compare by ordinal/name/ordering) - Regular columns, compared by column name (see
String.compareTo(String)
).
