Class AbstractInstanceClassFactory<T>

java.lang.Object

org.jboss.managed.plugins.factory.AbstractInstanceClassFactory<T>

Type Parameters:

T - the instance type

All Implemented Interfaces:

InstanceClassFactory<T>

Direct Known Subclasses:

DefaultInstanceClassFactory

public abstract class AbstractInstanceClassFactory<T>
extends Object
implements InstanceClassFactory<T>

A base InstanceClassFactory implementation that uses jboss reflection to get/set values on the underlying property object. Runtime component names are handled via a mapping from TypeInfo to RuntimeComponentNameTransformer using property ManagementRuntimeRef information.
