KronoGraph License Configuration

Copy link to this section

Overview

Starting with KronoGraph v7, the license handling has changed. The license is now managed through the UiSdlGraphConfig type and must be configured on a per-application basis.

License Requirement

The KronoGraph library requires a valid license to render time graph visualizations. If no license is configured in UiSdlGraphConfig, the time graph will not render.

License Management

The license is managed by C3 and provided through configuration. Application developers do not need to obtain or manage the license directly, but they must ensure the configuration is properly set up in their application.

Configuration Type

The UiSdlGraphConfig type (same type used for ReGraph) provides access to time graph visualization configuration settings. This type mixes Configurable<UiSdlGraphConfigSettings> and Singleton, allowing centralized management of the license token.

Key Methods

• setAccessToken(accessToken): Sets the graph visualization access token.
• getAccessToken(): Retrieves the configured access token.
• clearAccessToken(): Clears the configured access token.
• configWithAccessToken(): Returns the configuration settings with the access token.

Setting Up the License in Your Application

To configure the KronoGraph license in your application:

1. Get the UiSdlGraphConfig instance:

   JavaScript

   Copy code to clipboard

   var graphConfig = UiSdlGraphConfig.inst();

2. Set the access token provided by C3:

   JavaScript

   Copy code to clipboard

   graphConfig.setAccessToken('your_access_token');

3. Verify the token is set:

   JavaScript

   Copy code to clipboard

   const accessToken = graphConfig.getAccessToken();

Important Notes

• The license must be defined on a per-application basis.
• Without a valid license configured, time graph visualizations will not render.
• The access token is stored securely using the @config(secret=true) annotation in UiSdlGraphConfigSettings.
• The same UiSdlGraphConfig type is used for both ReGraph and KronoGraph license configuration.
• Contact your C3 representative to obtain the appropriate license for your application.
