org.jolokia.util.ServiceObjectFactory

public final class ServiceObjectFactory
extends Object

A simple factory for creating services with no-arg constructors from a textual descriptor. This descriptor, which must be a resource loadable by this class' classloader, is a plain text file which looks like

   org.jolokia.detector.TomcatDetector,50
   !org.jolokia.detector.JettyDetector
   org.jolokia.detector.JBossDetector
   org.jolokia.detector.WebsphereDetector,1500
 

If a line starts with ! it is removed if it has been added previously. The optional second numeric value is the order in which the services are returned.

Method Detail

createServiceObjects

public static <T> List<T> createServiceObjects(String... pDescriptorPaths)

Create a list of services ordered according to the ordering given in the service descriptor files. Note, that the descriptor will be looked up in the whole classpath space, which can result in reading in multiple descriptors with a single path. Note, that the reading order for multiple resources with the same name is not defined.

Type Parameters:

T - type of the service objects to create

Parameters:

pDescriptorPaths - a list of resource paths which are handle in the given order. Normally, default service should be given as first parameter so that custom descriptors have a chance to remove a default service.

Returns:

a ordered list of created services or an empty list.
