Package org.jboss.as.server.moduleservice

Class ExternalModuleService

java.lang.Object
org.jboss.as.server.moduleservice.ExternalModuleService
All Implemented Interfaces:
ExternalModule, org.jboss.msc.Service, org.jboss.msc.service.Service<ExternalModuleService>, org.jboss.msc.value.Value<ExternalModuleService>
public class ExternalModuleService extends Object implements org.jboss.msc.service.Service<ExternalModuleService>, ExternalModule
Service that manages external modules.

Once external modules are installed there is currently no way to safely remove the module spec service, however as they are on-demand services if all dependent services are stopped then the actual Module will be unloaded.

TODO: support removing modules when msc can tell us that nothing depends on the service.

    • isValidFile

      public boolean isValidFile(String path)
      Description copied from interface: ExternalModule
      Checks if the path argument refers to a file and the file is valid to be used as a class-path entry.
      Specified by:
      isValidFile in interface ExternalModule
      Parameters:
      path - value to test.
      Returns:
      true if and only if the path refers to a file and the file is considered valid as a class-path entry, otherwise returns false.

    • addExternalModuleAsString

      public String addExternalModuleAsString(String path, org.jboss.msc.service.ServiceRegistry serviceRegistry, org.jboss.msc.service.ServiceTarget serviceTarget)
      Description copied from interface: ExternalModule
      Prepares and install a new module and ExternalModuleSpecService to manage this module.

      This method does not use a specific module name, instead the module name is derived from the given path. This method prevents the creation of duplicate external module spec services for the given path looking at the service registry, so it can be called multiple times using the same path.

      Specified by:
      addExternalModuleAsString in interface ExternalModule
      Parameters:
      path - An absolute path pointing out to a directory or jar file that will be used as source for the resources backed by the given module name we want to install. Cannot be null
      serviceRegistry - The MSC service registry which will be used to find if there is already an ExternalModuleSpecService created for the given path. Cannot be null.
      serviceTarget - The ServiceTarget to use to install the service. Cannot be null.
      Returns:
      The string representing the Module Identifier created for the given path.

    • addExternalModuleAsString

      public String addExternalModuleAsString(String moduleName, String path, org.jboss.msc.service.ServiceRegistry serviceRegistry, org.jboss.msc.service.ServiceTarget serviceTarget)
      Description copied from interface: ExternalModule
      Prepares and install a new Module Identifier string and ExternalModuleSpecService to manage this module. This method prevents the creation of duplicate external module spec services for the given module name looking at the service registry, so it can be called multiple times for the same module name.
      Specified by:
      addExternalModuleAsString in interface ExternalModule
      Parameters:
      moduleName - The module name to add.
      path - An absolute path pointing out to a directory or jar file that will be used as source for the resources backed by the given module name we want to install. Cannot be null
      serviceRegistry - The MSC service registry which will be used to find if there is already an ExternalModuleSpecService created for the given module name. Cannot be null.
      serviceTarget - The ServiceTarget to use to install the service. Cannot be null.
      Returns:
      The Module Identifier as a String of the module created for the given path.
