public class HibernatePojoDataSource
extends PersistentPojoDataSource

A data source for working with Hibernate POJOs. When the application is loaded the datasources are instantiated and in the case of a PojoDataSource the PojoRoot instance specified by the root element is instantiated and configured. The configuration project involves traversing the class hierarchy and setting up PojoModel nodes or proxies for each class in the pojo hierarchy, applying Hibernate mapping configuration to the POJO adapters that are used in the application. The configuration can specify naming overrides if the names established by reflection are not suitable

Constructor Detail

HibernatePojoDataSource

public HibernatePojoDataSource(Project project)

Creates a new instance of HibernatePojoDataSource

Parameters:

project - the owner project

Method Detail

getOverrideXml

protected XmlElement getOverrideXml(PojoAdapter adapter)

Gets the xml element describing overrides of the class being adapted by the specified adapter. The runtime class name might be different from the one defined in the source code because of the Hibernate proxy object.

Overrides:

getOverrideXml in class PojoDataSource

Parameters:

adapter - the adapter object

Returns:

XmlElement object describing the overrides.

overrideAdapter

protected void overrideAdapter(PojoAdapter adapter)

Overrides the specified adapter, adds the information about lazily initialized properties.

Overrides:

overrideAdapter in class PersistentPojoDataSource

Parameters:

adapter - the adapter to be overrided.

createPojoModel

protected PojoModel createPojoModel(DataModel parent,
                                    java.lang.String subPath)

Creates and returns a new instance of HibernatePojoModel

Overrides:

createPojoModel in class PersistentPojoDataSource

Parameters:

parent - the parent model of the model node which is to be created

subpath - String consisting of pojo properties, must be in the format: propertyName(arguments...)[idx]

Returns:

PojoModel object

createPojoModel

protected PojoModel createPojoModel(DataModel parent,
                                    java.lang.Object pojo)

Creates and returns a new instance of HibernatePojoModel

Overrides:

createPojoModel in class PersistentPojoDataSource

Parameters:

parent - the parent model node

Returns:

PojoModel object
