Class EjbExtractor

java.lang.Object
  org.apache.myfaces.orchestra.dynaForm.metadata.impl.ejb.EjbExtractor

All Implemented Interfaces:

Extractor

Direct Known Subclasses:

HibernateExtractor

public class EjbExtractor
extends Object
implements Extractor

Extract metadata from ejb3 beans.

This class makes a whole lot of assumptions.

It assumes that if there is a method getFoo(), and a field foo exists on the class then that field is a property.

Method Detail

getMetaData

public void getMetaData(MetaDataWritable metaData,
                        Object entity)

Implement the Extractor interface.

The entity parameter must be a String containing the fully-qualified name of a java class.

The specified class and its ancestors are inspected for JPA annotations, and

Specified by:

getMetaData in interface Extractor

createClassList

protected void createClassList(List<Class<?>> classes,
                               Class<?> clazz)

get all super classes needed to be parsed.

Populates the classes list with the complete superclass chain of the specified class. At return the first entry added to the list is the furthest ancestor that is NOT Object.class, and the last entry in the list is the clazz parameter itself.

create

getMethods

protected Method[] getMethods(Class<?> entityClass)

getFields

protected Field[] getFields(Class<?> entityClass)

initFromFields
