Interface GatewayModuleHook

  • All Known Implementing Classes:
    AbstractGatewayModuleHook, ReportingGatewayHook, SfcGatewayHook, TagHistorianGatewayHook

    public interface GatewayModuleHook
    The main hook into a module's gateway scope. Each module should provide exactly one implementation of this hook class if the module includes gateway-scoped logic. The name of this implementation must be included in the module's descriptor file, with an entry like:

     <hook scope="G">com.example.module.gateway.SuperHookClass</hook>

    Best practice: Instead of implementing this interface directly, subclass your hook class from AbstractGatewayModuleHook instead.

    • Method Detail

      • setup

        void setup​(GatewayContext context)
        Called to before startup. This is the chance for the module to add its extension points and update persistent records and schemas. None of the managers will be started up at this point, but the extension point managers will accept extension point types.
      • startup

        void startup​(LicenseState activationState)
        Called to initialize the module. Will only be called once. Persistence interface is available, but only in read-only mode.
      • shutdown

        void shutdown()
        Called to shutdown this module. Note that this instance will never be started back up - a new one will be created if a restart is desired
      • getRPCHandler

        java.lang.Object getRPCHandler​(ClientReqSession session,
                                       java.lang.String projectName)
        A class whose functions will become exposed automatically through reflection to the Designer and the Client through RPC
      • notifyLicenseStateChanged

        void notifyLicenseStateChanged​(LicenseState licenseState)
        Notify module hook when the license state has changed. This could only contain changes for the module or it could contain a change to the platform license (version, restrictions such as expiration date, sqltag count...)
      • getHomepagePanels

        java.util.List<? extends IHomepagePanelDescriptor> getHomepagePanels()
        A list (may be null or empty) of homepage panels that this module provides
      • getStatusPanels

        java.util.List<? extends INamedTab> getStatusPanels()
        A list (may be null or empty) of panels to display in the status section
      • getConfigPanels

        default java.util.List<? extends IConfigTab> getConfigPanels()
        A list (may be null or empty) of panels to display in the config section. Note that any config panels that are part of a category that doesn't exist already or isn't included in getConfigCategories() will not be shown.
      • getConfigCategories

        default java.util.List<ConfigCategory> getConfigCategories()
        A list (may be null or empty) of custom config categories needed by any panels returned by getConfigPanels()
      • configureSerializer

        void configureSerializer​(XMLSerializer serializer)
        Provides the module a chance to add serialization delegates to the serializer custom for classes that might be encountered when serializing objects provided by this module
      • configureDeserializer

        void configureDeserializer​(XMLDeserializer deserializer)
        Provides the module a chance to configure the deserializer with any custom handlers
      • configureFunctionFactory

        void configureFunctionFactory​(ExpressionFunctionManager factory)
        Provides the module with an opportunity to define its own expression functions
      • updateSystemMap

        default void updateSystemMap​(SystemMap map)
        Instead, see getStatusOverviewContributor
        This is no longer used.
        deprecated since 7.9.0
      • getMountedResourceFolder

        default java.util.Optional<java.lang.String> getMountedResourceFolder()
        the path to a folder in one of the module's gateway jar files that should be mounted at /res/module-id/foldername
      • mountRouteHandlers

        default void mountRouteHandlers​(RouteGroup routes)
        Provides a chance for the module to mount any route handlers it wants. These will be active at /main/data/module-id/* See RouteGroup for details. Will be called after startup().
      • getMountPathAlias

        default java.util.Optional<java.lang.String> getMountPathAlias()
        Used by the mounting underneath /res/module-id/* and /main/data/module-id/* as an alternate mounting path instead of your module id, if present.
      • isFreeModule

        default boolean isFreeModule()
        true if this is a "free" module, i.e. it does not participate in the licensing system. This is equivalent to the now defunct FreeModule attribute that could be specified in module.xml.
      • getStatusOverviewContributor

        default java.util.Optional<OverviewContributor> getStatusOverviewContributor()
        Implement this method to contribute meta data to the Status section's Systems / Overview page.
      • getConfigOverviewContributor

        default java.util.Optional<ConfigOverviewContributor> getConfigOverviewContributor()
        Implement this method to contribute meta data to the Configure section's Overview page.
      • onMountedResourceRequest

        default void onMountedResourceRequest​(java.lang.String resourcePath,
                                              javax.servlet.http.HttpServletResponse response)
        Called prior to a 'mounted resource request' being fulfilled by requests to the mounted resource servlet serving resources from /res/module-id/ (or /res/alias/ if getMountPathAlias() is implemented). It is called after the target resource has been successfully located.

        Primarily intended as an opportunity to amend/alter the response's headers for purposes such as establishing Cache-Control. By default, Ignition sets no additional headers on a resource request.

        resourcePath - path to the resource being returned by the mounted resource request
        response - the response to read/amend.
