All Implemented Interfaces:
AssemblerBrokerService, Initable, Service

public class TurbineAssemblerBrokerService
extends TurbineBaseService
implements AssemblerBrokerService

TurbineAssemblerBrokerService allows assemblers (like screens, actions and layouts) to be loaded from one or more AssemblerFactory classes. AssemblerFactory classes are registered with this broker by adding them to the TurbineResources.properties file.
