java.lang.Object
- org.apache.openjpa.meta.InheritanceComparator
- - org.apache.openjpa.meta.MetaDataInheritanceComparator
  - - org.apache.openjpa.persistence.XMLPersistenceMetaDataSerializer.SerializationComparator

All Implemented Interfaces:

Serializable, Comparator

Direct Known Subclasses:

XMLPersistenceMappingSerializer.MappingSerializationComparator

Enclosing class:

XMLPersistenceMetaDataSerializer
```
protected class XMLPersistenceMetaDataSerializer.SerializationComparator
extends MetaDataInheritanceComparator
```
Compares clases, sequences, and queries to order them for serialization. Places sequences first, then classes, then queries. Sequences and queries are ordered alphabetically by name. Classes are placed in listing order, in inheritance order within that, and in alphabetical order within that.
