public abstract class DirectoryServerPlugin<T extends PluginCfg> extends Object
This class defines the set of methods and structures that are available for use in Directory Server plugins. This is a single class that may be used for all types of plugins, and an individual plugin only needs to implement the specific methods that are applicable to that particular plugin type.

  • Constructor Details

    • DirectoryServerPlugin

      protected DirectoryServerPlugin()
      Creates a new instance of this Directory Server plugin. Every plugin must implement a default constructor (it is the only one that will be used to create plugins defined in the configuration), and every plugin constructor must call super() as its first action.

  • Method Details

    • getServerContext

      protected ServerContext getServerContext()
      Returns the server context.
      Returns:
      the server context.

    • isConfigurationAcceptable

      public boolean isConfigurationAcceptable(T configuration, List<LocalizableMessage> unacceptableReasons)

      Parameters:
      configuration - The plugin configuration for which to make the determination.
      unacceptableReasons - A list that may be used to hold the reasons that the provided configuration is not acceptable.
      Returns:

      Parameters:
      pluginTypes - The set of plugin types that indicate the ways in which this plugin will be invoked.
      configuration - The configuration for this plugin.
      Throws:
