org.apache.jdo.impl.model.java.runtime.jdk5.JDK5RuntimeJavaModelFactory
- All Implemented Interfaces:
- org.apache.jdo.model.java.JavaModelFactory
public class JDK5RuntimeJavaModelFactory
- extends RuntimeJavaModelFactory
A reflection based JavaModelFactory implementation used at runtime in a
J2SE5.0 environment.
The implementation takes java.lang.Class
and
java.lang.reflect.Field
instances to get Java related
metadata about types and fields. This implementation caches JavaModel
instances per ClassLoader.
JDK5RuntimeJavaModelFactory implements the singleton pattern; method
getInstance()
provides access to the singleton factory
instance. This method also registers a model listener at the
JDOImplHelper to handle the runtime metadata as generated by the
enhancer.

- JDO 2.0

JDK5RuntimeJavaModelFactory
protected JDK5RuntimeJavaModelFactory()
- Creates a new RuntimeJavaModelFactory. This constructor should not
be called directly; instead, the singleton access method
getInstance()
should be used.
getInstance
public static JDK5RuntimeJavaModelFactory getInstance()
throws org.apache.jdo.model.ModelFatalException
- Returns the singleton instance of JDK5RuntimeJavaModelFactory. On first
call it registers a model listener at the JDOImplHelper.
This method checks that the caller is authorized for
JDOPermission("getMetadata")
, and if not, throws
ModelFatalException
wrapping the SecurityException.
- Returns:
- RuntimeJavaModelFactory instance
- Throws:
org.apache.jdo.model.ModelFatalException
- if the caller does not have the
getMetadata permission.
newJavaModelInstance
protected org.apache.jdo.model.java.JavaModel newJavaModelInstance(java.lang.ClassLoader classLoader)
- Creates a new instance of the JavaModel implementation class.
This implementation returns a JDK5RuntimeJavaModel
instance.
- Overrides:
newJavaModelInstance
in class RuntimeJavaModelFactory
- Returns:
- a new JavaModel instance.
