  com.jcorporate.expresso.core.dataobjects.DataObjectFactory

public final class DataObjectFactory

extends Object

Constructs 'often' DataObjects based upon standard order of initialization and the interfaces it implements. For example, Defineable objects must have setDefinition() called first, then setDataContext(), then setUid()

Method Detail

createObject

public static Object createObject(Class clazz,
                                  String dataContext,

Parameters:

clazz - Object class name

dataContext - Database context

uid - the user id that will be set if the object is Securable

Returns:

an instantiated and properly constructed object.

Throws:

DataException - upon error

createDataObject

                                          String dataContext,
                                          int uid)
                                   throws DataException

createDataObject

public static DataObject createDataObject(Class clazz,
                                          String dataContext,
                                          String definition,

Returns:

an instantiated and properly constructed DataObject.

Throws:

DataException - upon error

createObject

public static Object createObject(Class clazz,
                                  String dataContext,
                                  String definition,
                                  int uid)
                           throws DataException

Create an object given the class, datacontext, definition and uid.

Parameters:

definition - The definition to define the Defineable Object. If the object does not implement Defineable, this parameter may be null.

clazz - Object class

dataContext - Database context

uid - the user id that will be set if the object is Securable

Returns:

an instantiated and properly constructed object.

Throws:

DataException - upon error
