Class
caplin.security.permissioning

AbstractPermissionService

Implements caplin.services.security.PermissionService.
This class allows you to query the product permissions of the currently logged in user, or the permissions they have when they are trading on behalf of another user.

The methods of the PermissionService class fall into three distinct categories. Methods in the first category return permissioning data when called. This category can be used by the classes of your application that respond to user interactions. An example of where this category could be employed would be in the code that responds to user attempts to open a trade ticket. In this case the permission is determined when the user initiates the action.

Methods that return permissioning data when called are:

Methods in the second category allow you to register listeners that subscribe to current and future product permissions. This category can be used to register the classes of your application that need to be notified when user permissions change.

An example of where this category would be employed is in the code responsible for displaying trade tiles. Trade tiles are typically grouped in one or more panels on the screen and are always on display. If a user permission changes, this may require the status of one or more trade tiles to change; for example, the button that allows the user to trade from the tile may need to be disabled. By attaching a permission listener to the tile its status can be changed independently of what the user is doing; it is not be necessary for the user to initiate an action on the trade tile for the change in permission to take effect.

Methods that register or remove listeners are:

Methods in the third (and final) category allow you to retrieve user attributes. A user can be assigned any number of attributes in the form of name/value pairs. User attributes are not processed by the Permissioning Auth Module and therefore do not affect permissioning directly. A typical use would be to send information to Caplin Trader about the maximum tradable amount that a user is permitted to trade. Your application could then use this information to limit the tradeable amounts shown to the user.

Methods that return the value of a user attribute when called are #getUserAttribute and #getToboUserAttribute. Methods that register a subscription listener to current and future values of a user attribute are #addAttributeListener and #addToboUserAttributeListener.

Trading on behalf of (TOBO)

When a logged in user is 'trading on behalf of' (TOBO) another user, the permissions that are sent to and cached by the permissioning library depend on the permissioning mode the Permissioning Auth Module is configured to run in.

If the permissioning mode is SalesUser, only permissions for the logged in user are sent to the permissioning library. In this mode, the methods that return product permissions always return permissions for the logged in user, even if that user is trading on behalf of another user.

If the permissioning mode is SalesIntersectCustomerUser, permissions for both the logged in user and the user they are trading on behalf of are sent to and cached by the permissioning library. In this mode, the permissions returned by the methods of this class are the logical AND of the logged in user and the user they are trading on behalf of.

For permissions that reside in specified namespaces, the permissioning library can be configured to return permissions for the logged in user only, even if that user is trading on behalf of another user and the permissioning mode is SalesIntersectCustomerUser. For further information about setting up this configuration, refer to the document Caplin Trader: Permissioning Configuration XML Reference.

Constructor Detail

► caplin.security.permissioning.AbstractPermissionService()

This class returns permissioning data for the currently logged in user.

Method Detail

► void addAttributeListener(String sAttributeName, caplin.services.security.PermissionServiceListener oListener)

Registers a listener that subscribes to current and future values of a single user attribute. After calling this method, the registered listener will be notified of the value of the user attribute.

This is the value assigned to the logged in user. To be notified of the value assigned to the user they are trading on behalf of, call #addToboUserAttributeListener instead.

The listener that you register must implement caplin.services.security.PermissionServiceListener#onAttributeChanged, which is called when the listener is first registered and also when the value of the attribute changes.

Parameters
String sAttributeName The name of the user attribute that you want to subscribe to.
caplin.services.security.PermissionServiceListener oListener The listener object that will receive the subscription updates.

► int addGlobalPermissionListener(String sProduct, String sAction, caplin.services.security.PermissionServiceListener oListener)

Registers a listener that subscribes to current and future permissions for an action on a single product in the global (default) namespace. After calling this method, the registered listener will be notified of the permission that the user has for the requested action on the specified product.

The listener that you register must implement caplin.services.security.PermissionServiceListener#onSinglePermissionChanged, which is called when the listener is first registered and also when the product permission changes.

Note: If you want to specify a different namespace, then use #addPermissionListener instead.

Parameters
String sProduct The name of the product that the subscription is for (for example "/FX/EURUSD").
String sAction The action that the subscription is for (for example "TRADE").
caplin.services.security.PermissionServiceListener oListener The listener object that will receive the subscription updates.
