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.

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

    • moduleSpecServiceName

      public static org.jboss.msc.service.ServiceName moduleSpecServiceName(String identifier)
      Returns the corresponding ModuleSpec service name for the given module.
      Parameters:
      identifier - The module identifier string, method does not support non-canonized identifiers
      Returns:
      The service name of the ModuleSpec service

    • installModuleResolvedService

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

      Returns true if the module identifier is a dynamic module that will be loaded by this module loader
      Parameters:
      identifier - The module identifier string, method does not support non-canonized identifiers
      Returns:
      Whether the module identifier is a dynamic module

    • moduleServiceName

      public static org.jboss.msc.service.ServiceName moduleServiceName(String identifier)
      Returns the corresponding ModuleLoadService service name for the given module.
      Parameters:
      identifier - The module identifier string, method does not support non-canonized identifiers
      Returns:
      The service name of the ModuleLoadService service
