Except he might not know what the business is...
What Steve is trying to say; :o)
1. Get the reference to the <container> where the "start" component is
located by,
/** @avalon.entry key="urn:composition:containment.model"
* type="org.apache.avalon.composition.model.ContainmentModel"
*/
public void contextualize( Context ctx )
{
m_Model = (ContainmentModel)
ctx.get( "urn:composition:containment.model" );
}
Technically (probably considered bad practice) you can also retrieve any
container within the application, by getModel(), for instance getModel( "/"
), returns the root container (although it might be the root application
container in the future).
2. Any point later in time, you can "load" another container/block dynamically
by doing;
m_Model.addContainmentModel( blockUrl );
or
m_Model.addContainmentModel( blockUrl, configUrl );
This will behave as if those blocks were "launched" at Merlin startup.
3. And you can equally do the opposite, remove the block later.
