## org.apache.cayenne.ashwood
Class AshwoodEntitySorter

    java.lang.Object
      org.apache.cayenne.ashwood.AshwoodEntitySorter

All Implemented Interfaces:
  EntitySorter

Direct Known Subclasses:
  AshwoodEntitySorter

    public class AshwoodEntitySorter

extends java.lang.Object
implements EntitySorter

Implements dependency sorting algorithms for ObjEntities, DbEntities and DataObjects. Presently it works for acyclic database schemas with possible multi-reflexive tables.

Since:
  3.1

Field Summary
`protected java.util.Map<DbEntity,org.apache.cayenne.ashwood.AshwoodEntitySorter.ComponentRecord>` | `components`
`protected java.util.Comparator<DbEntity>` | `dbEntityComparator`
`protected EntityResolver` | `entityResolver`
`protected java.util.Comparator<ObjEntity>` | `objEntityComparator`
`protected java.util.Map<DbEntity,java.util.List<DbRelationship>>` | `reflexiveDbEntities`

Constructor Summary
`AshwoodEntitySorter()`
`AshwoodEntitySorter(java.util.Collection<DataMap> dataMaps)` Deprecated. since 3.1. Use `AshwoodEntitySorter()` constructor together with `setDataMaps(Collection)` instead.

Method Summary
`protected void` | `doIndexSorter()` Reindexes internal sorter without synchronization.
`protected java.lang.Object` | `findReflexiveMaster(Persistent object, ObjRelationship toOneRel, java.lang.String targetEntityName)`
`protected java.util.Comparator<DbEntity>` | `getDbEntityComparator(boolean dependantFirst)`
`protected java.util.Comparator<ObjEntity>` | `getObjEntityComparator(boolean dependantFirst)`
`protected void` | `indexSorter()` Reindexes internal sorter in a thread-safe manner.
`protected boolean` | `isReflexive(DbEntity metadata)`
`void` | `setDataMaps(java.util.Collection<DataMap> dataMaps)` Deprecated. since 3.1, `setEntityResolver(EntityResolver)` is used instead.
`void` | `setEntityResolver(EntityResolver entityResolver)` Sets EntityResolver for this sorter.
`void` | `sortDbEntities(java.util.List<DbEntity> dbEntities, boolean deleteOrder)` Sorts a list of DbEntities.
`void` | `sortObjectsForEntity(ObjEntity objEntity, java.util.List<?> objects, boolean deleteOrder)` Sorts a list of objects belonging to the ObjEntity.
`void` | `sortObjEntities(java.util.List<ObjEntity> objEntities, boolean deleteOrder)` Sorts a list of ObjEntities.
