org.objectstyle.cayenne.project
Class NamedObjectFactory  

java.lang.Object
  org.objectstyle.cayenne.project.NamedObjectFactory

Direct Known Subclasses:

NamedObjectFactory.DataDomainFactory, NamedObjectFactory.DataMapFactory, NamedObjectFactory.DataNodeFactory, NamedObjectFactory.DbEntityFactory, NamedObjectFactory.ObjAttributeFactory, NamedObjectFactory.ObjEntityFactory, NamedObjectFactory.ObjRelationshipFactory, NamedObjectFactory.ProcedureFactory, NamedObjectFactory.ProcedureParameterFactory

---

public abstract class NamedObjectFactory

extends java.lang.Object

Factory class that generates various Cayenne objects with default names that are unique in their corresponding context. Supports creation of the following objects:

• DataMap
• ObjEntity
• ObjAttribute
• ObjRelationship
• DbEntity
• DerivedDbEntity
• DbAttribute
• DerivedDbAttribute
• DbRelationship
• DataNode
• DataDomain
• Procedure
• ProcedureParameter

This is a helper class used mostly by GUI and database reengineering classes.

Method Detail

createName

public static java.lang.String createName(java.lang.Class objectClass,
                                          java.lang.Object namingContext)

---

createObject

public static java.lang.Object createObject(java.lang.Class objectClass,
                                            java.lang.Object namingContext)

Creates an object using an appropriate factory class. If no factory is found for the object, NullPointerException is thrown.

Note that newly created object is not added to the parent. This behavior can be changed later.

---

createRelationship

public static org.objectstyle.cayenne.map.Relationship createRelationship(org.objectstyle.cayenne.map.Entity srcEnt,
                                                                          org.objectstyle.cayenne.map.Entity targetEnt,
                                                                          boolean toMany)

Creates a relationship using an appropriate factory class. If no factory is found for the object, NullPointerException is thrown.

Note that newly created object is not added to the parent. This behavior can be changed later.

---

makeName

protected java.lang.String makeName(java.lang.Object namingContext)

Creates a unique name for the new object and constructs this object.

---

makeObject

protected java.lang.Object makeObject(java.lang.Object namingContext)

Creates a unique name for the new object and constructs this object.

---

nameBase

protected abstract java.lang.String nameBase()

Returns a base default name, like "UntitledEntity", etc.

---

create

protected abstract java.lang.Object create(java.lang.String name,
                                           java.lang.Object namingContext)

Internal factory method. Invoked after the name is figured out.

---

isNameInUse

protected abstract boolean isNameInUse(java.lang.String name,
                                       java.lang.Object namingContext)

Checks if the name is already taken by another sibling in the same context.
