public class SimpleAmetysObjectFactory
extends AbstractLogEnabled
implements JCRAmetysObjectFactory<SimpleAmetysObject>, Configurable, Serviceable

Default implementation of an JCRAmetysObjectFactory, handling SimpleAmetysObject.
This implementation takes its scheme and nodetype through a configuration:
<extension point="org.ametys.plugins.repository.AmetysObjectFactoryExtensionPoint"
id="XXXX" class="org.ametys.plugins.repository.DefaultAmetysObjectFactory">
<scheme>your_scheme</scheme>
<nodetype>your:nodetype</nodetype>
[<nodetype>your:nodetype2</nodetype>]
[...]
</extension>
This implementation manages only one nodetype.
