Method Details

get

public static GatewayHook get(@Nonnull
 GatewayContext context)

getComponentModelDelegateRegistry

public ComponentModelDelegateRegistry getComponentModelDelegateRegistry()

setup

public void setup(GatewayContext gatewayContext)

Description copied from interface: GatewayModuleHook

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.

Specified by:

setup in interface GatewayModuleHook

startup

public void startup(LicenseState activationState)

Description copied from interface: GatewayModuleHook

Called to initialize the module. Will only be called once. Persistence interface is available, but only in read-only mode.

Specified by:

startup in interface GatewayModuleHook

shutdown

public 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.

Specified by:

shutdown in interface GatewayModuleHook

isMakerEditionCompatible

public boolean isMakerEditionCompatible()

Specified by:

isMakerEditionCompatible in interface GatewayModuleHook

Returns:

true if this module opts-in to participating in Ignition Maker Edition. Default is false. If you override this and return true, your module will become activated when running in a Maker Edition installation.

handleMessage

public List<String> handleMessage(com.inductiveautomation.ignition.gateway.clientcomm.scriptmsg.event.SessionMessageDispatchEvent event)

Specified by:

handleMessage in interface com.inductiveautomation.ignition.gateway.clientcomm.scriptmsg.event.SessionMessageDispatchHandler

getContext

public GatewayHook.PerspectiveGatewayContext getContext()

getRedundancyStatus

@Nullable
public RedundancyStatus getRedundancyStatus()

notifyLicenseStateChanged

public void notifyLicenseStateChanged(LicenseState platformLicense)

Description copied from interface: GatewayModuleHook

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...)

Specified by:

notifyLicenseStateChanged in interface GatewayModuleHook

Overrides:

notifyLicenseStateChanged in class AbstractGatewayModuleHook

getLicenseState

public PerspectiveLicenseState getLicenseState()

getMountedResourceFolder

public Optional<String> getMountedResourceFolder()

Specified by:

getMountedResourceFolder in interface GatewayModuleHook

Returns:

the path to a folder in one of the module's gateway jar files that should be mounted at /main/res/module-id/foldername

getMountPathAlias

public Optional<String> getMountPathAlias()

Description copied from interface: GatewayModuleHook

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.

Specified by:

getMountPathAlias in interface GatewayModuleHook

mountRouteHandlers

public 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().

Specified by:

mountRouteHandlers in interface GatewayModuleHook

Parameters:

routes - the routes group, used to serve data via http requests to the Ignition Gateway

getStatusOverviewContributor

public Optional<OverviewContributor> getStatusOverviewContributor()

Description copied from interface: GatewayModuleHook

Implement this method to contribute meta data to the Status section's Systems / Overview page.

Specified by:

getStatusOverviewContributor in interface GatewayModuleHook

initializeScriptManager

public void initializeScriptManager(ScriptManager manager)

Description copied from interface: GatewayModuleHook

Initialize a newly-instantiated script manager. This will be called exactly once for any given ScriptManager instance. Usually this will involve calling ScriptManager.addScriptModule(String, Object), which reflectively loads the public (instance and static) java functions from the given object into the scripting environment, at the provided path.

This function may be called before GatewayModuleHook.startup(LicenseState), but never before GatewayModuleHook.setup(GatewayContext).

Specified by:

initializeScriptManager in interface GatewayModuleHook

Overrides:

initializeScriptManager in class AbstractGatewayModuleHook

getStatusPanels

public List<? extends INamedTab> getStatusPanels()

Description copied from interface: GatewayModuleHook

A list (may be null or empty) of panels to display in the status section

Specified by:

getStatusPanels in interface GatewayModuleHook

Overrides:

getStatusPanels in class AbstractGatewayModuleHook

getRPCHandler

public PerspectiveModuleRpc getRPCHandler(ClientReqSession session,
 String projectName)

Description copied from interface: GatewayModuleHook

A class whose functions will become exposed automatically through reflection to the Designer and the Client through RPC

Specified by:

getRPCHandler in interface GatewayModuleHook

Overrides:

getRPCHandler in class AbstractGatewayModuleHook

onMountedResourceRequest

public void onMountedResourceRequest(String resourcePath,
 javax.servlet.http.HttpServletResponse response)

Description copied from interface: GatewayModuleHook

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 GatewayModuleHook.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.

Specified by:

onMountedResourceRequest in interface GatewayModuleHook

Parameters:

resourcePath - path to the resource being returned by the mounted resource request

response - the response to read/amend.

isClientCacheEnabled

public static boolean isClientCacheEnabled()

getMaxIdleTimeMs

public static long getMaxIdleTimeMs()

getIdleTimeIntervalMs

public static long getIdleTimeIntervalMs()

getHelloResponseTimeoutMs

public static long getHelloResponseTimeoutMs()

getConfigPanels

public List<? extends IConfigTab> getConfigPanels()

Description copied from interface: GatewayModuleHook

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 GatewayModuleHook.getConfigCategories() will not be shown.

Specified by:

getConfigPanels in interface GatewayModuleHook

getConfigCategories

public List<ConfigCategory> getConfigCategories()

Description copied from interface: GatewayModuleHook

A list (may be null or empty) of custom config categories needed by any panels returned by GatewayModuleHook.getConfigPanels()

Specified by:

getConfigCategories in interface GatewayModuleHook
