Method Details

findViewConfig

public CompletableFuture<Optional<ViewConfig>> findViewConfig(String viewPath)

Description copied from interface: Session

Returns a CompletableFuture that completes to present an Optional<ViewConfig> for the specified path. The use of the future is to allow for the asynch collection of configs for views which are retrieved via asynchronous processes, as is the case when a view is being edited/altered in the designer.

Parameters:

viewPath - path to the view's project resource within the project being run.

getProject

@Nonnull
public PerspectiveProject getProject()

Description copied from interface: InternalSession

Fetch the project associated with this session.

Returns:

the PerspectiveProject associated with this session

createViewModel

public ViewModel createViewModel(PageModel group,
 ViewInstanceId id,
 ViewConfig config,
 com.inductiveautomation.ignition.common.gson.JsonObject params)

getTagManager

public TagManager getTagManager()

getTagHistoryManager

public TagHistoryManager getTagHistoryManager()

getScriptManager

public ScriptManager getScriptManager()

getNamedQueryManager

public NamedQueryManager getNamedQueryManager()

getPageTimeout

public long getPageTimeout()

getWebAuthStatus

@Nonnull
public WebAuthStatus getWebAuthStatus()

Returns:

the WebAuthStatus for this Session

maybeScheduleReaper

protected void maybeScheduleReaper()

Description copied from class: AbstractSession

Call this when it's possible the last page has been closed. The session will then schedule the reaper to close the session itself (runtime sessions only, designer sessions don't reap in this way)

Specified by:

maybeScheduleReaper in class AbstractSession<SecuredPerspectiveProjectSession>

onStartup

protected void onStartup()

Overrides:

onStartup in class SessionKernelWrapper<SecuredPerspectiveProjectSession>

onShutdown

protected void onShutdown()

Overrides:

onShutdown in class SessionKernelWrapper<SecuredPerspectiveProjectSession>

onSessionInit

public void onSessionInit(com.inductiveautomation.ignition.common.gson.JsonObject sessionInitResponse)

Description copied from class: AbstractSession

Called when handling the session-init message. Gives the project session a chance to add things to the response

Specified by:

onSessionInit in interface InternalSession

Overrides:

onSessionInit in class AbstractSession<SecuredPerspectiveProjectSession>

Parameters:

sessionInitResponse - the response JSON object to be passed back to the client in response to the session-init call

sendGatewayTime

protected void sendGatewayTime()

logout

public Optional<String> logout(@Nullable
 String message)

Description copied from interface: InternalSession

Logout of this session. The user will no longer be authenticated.

Parameters:

message - the message to display to the user after they are logged out of this session

Returns:

a logout token or hint for the IdP if one is available

onLoginResponse

public void onLoginResponse(WebAuthResponseContext webAuthResponseContext)

Description copied from interface: InternalSession

Called when the session receives a login response from the IdP

Parameters:

webAuthResponseContext - the login response object

onLogoutResponse

public void onLogoutResponse(WebAuthResponseContext webAuthResponseContext)

Description copied from interface: InternalSession

Called when this session received a logout response from the IdP

Parameters:

webAuthResponseContext - the logout response object

createPropertyReference

@Nonnull
public PropertyReference createPropertyReference(String referencePath,
 Consumer<PropertyTreeChangeEvent> subscriber,
 Set<Origin> acceptableOrigins)

Description copied from interface: PerspectiveElement

Create a PropertyReference with this PerspectiveElement as the target.

Parameters:

referencePath - the path to the property

subscriber - the subscriber - a Consumer of PropertyTreeChangeEvents

acceptableOrigins - the Set of Origins in which the subscriber is interested

Returns:

the PropertyReference

getLastActiveTime

public long getLastActiveTime()

closePage

public void closePage(String pageId)

Description copied from interface: InternalSession

Shuts down and removes the page associated with the given page ID which will disconnect the associated message channel (if one is connected).

Specified by:

closePage in interface InternalSession

Overrides:

closePage in class AbstractSession<SecuredPerspectiveProjectSession>

Parameters:

pageId - the page ID associated with the target page

newPage

@Nonnull
protected PageModel newPage(@Nonnull
 String pageId)

Overrides:

newPage in class AbstractSession<SecuredPerspectiveProjectSession>

destroySession

public void destroySession()

Description copied from interface: InternalSession

Destroys the session by removing it from its containing session collection and shutting it down (which should close any connected message channels).

close

public void close(@Nullable
 String message)

Description copied from interface: Session

Destroys this session and moves clients to a terminal state of closed

Parameters:

message - the message displayed to the client on the terminal state page
