Package org.jboss.as.server.moduleservice

Class ServiceModuleLoader

java.lang.Object

org.jboss.modules.ModuleLoader

org.jboss.as.server.moduleservice.ServiceModuleLoader

All Implemented Interfaces:

org.jboss.msc.Service, org.jboss.msc.service.Service<ServiceModuleLoader>, org.jboss.msc.value.Value<ServiceModuleLoader>

public class ServiceModuleLoader
extends org.jboss.modules.ModuleLoader
implements org.jboss.msc.service.Service<ServiceModuleLoader>

ModuleLoader that loads module definitions from msc services. Module specs are looked up in msc services that correspond to the module names.

Modules are automatically removed when the corresponding service comes down.

Method Detail

preloadModule

protected org.jboss.modules.Module preloadModule(String name)
                                          throws org.jboss.modules.ModuleLoadException

Overrides:

preloadModule in class org.jboss.modules.ModuleLoader

Throws:

org.jboss.modules.ModuleLoadException

findModule

public org.jboss.modules.ModuleSpec findModule(org.jboss.modules.ModuleIdentifier identifier)
                                        throws org.jboss.modules.ModuleLoadException

Overrides:

findModule in class org.jboss.modules.ModuleLoader

Throws:

org.jboss.modules.ModuleLoadException

toString

public String toString()

Overrides:

toString in class org.jboss.modules.ModuleLoader

start

public void start(org.jboss.msc.service.StartContext context)
           throws org.jboss.msc.service.StartException

Specified by:

start in interface org.jboss.msc.Service

Throws:

org.jboss.msc.service.StartException

stop

public void stop(org.jboss.msc.service.StopContext context)

Specified by:

stop in interface org.jboss.msc.Service

getValue

public ServiceModuleLoader getValue()
                             throws IllegalStateException,
                                    IllegalArgumentException

Specified by:

getValue in interface org.jboss.msc.value.Value<ServiceModuleLoader>

Throws:

IllegalStateException

IllegalArgumentException

relinkModule

public void relinkModule(org.jboss.modules.Module module)
                  throws org.jboss.modules.ModuleLoadException

Throws:

org.jboss.modules.ModuleLoadException

addService

public static void addService(org.jboss.msc.service.ServiceTarget serviceTarget,
                              Bootstrap.Configuration configuration)

moduleSpecServiceName

public static org.jboss.msc.service.ServiceName moduleSpecServiceName(org.jboss.modules.ModuleIdentifier identifier)

Returns the corresponding ModuleSpec service name for the given module.

Parameters:

identifier - The module identifier

Returns:

The service name of the ModuleSpec service

installModuleResolvedService

public static void installModuleResolvedService(org.jboss.msc.service.ServiceTarget serviceTarget,
                                                org.jboss.modules.ModuleIdentifier identifier)

moduleResolvedServiceName

public static org.jboss.msc.service.ServiceName moduleResolvedServiceName(org.jboss.modules.ModuleIdentifier identifier)

Returns the corresponding module resolved service name for the given module. The module resolved service is basically a latch that prevents the module from being loaded until all the transitive dependencies that it depends upon have have their module spec services come up.

Parameters:

identifier - The module identifier

Returns:

The service name of the ModuleSpec service

isDynamicModule

public static boolean isDynamicModule(org.jboss.modules.ModuleIdentifier identifier)

Returns true if the module identifier is a dynamic module that will be loaded by this module loader

moduleServiceName

public static org.jboss.msc.service.ServiceName moduleServiceName(org.jboss.modules.ModuleIdentifier identifier)

Returns the corresponding ModuleLoadService service name for the given module.

Parameters:

identifier - The module identifier

Returns:

The service name of the ModuleLoadService service
