Caplin Trader 4.8.0

Class: module:caplin/trading/service/TOBOUserServiceProvider

module:caplin/trading/service/TOBOUserServiceProvider

The TOBOUserServiceProvider class provides a implementation of the module:caplin/trading/service/TOBOUserService which uses the module:caplin/trading/service/TOBOUserPermissionServiceListener and the provided module:caplin/trading/service/TradePermissionService to get the permissions of the currently logged-in user, which users he can trade on behalf of, and which of there TOBO users' accounts can be used to this end.

The TOBOUserServiceProvider maintains a state consisting of the logged-in user's type (TRADER or SALES) selected TOBO user and account, and the list of available TOBO users and accounts for the selected TOBO user, if any. (SALES users are allowed to trade on behalf of other users whereas TRADER users are not.) This state is kept up-to-date by the permission listener. It also keeps track of the number of trades started by the logged-in user, locking all listeners if at least one trade is started.

The TOBOUserServiceProvider also acts as a module:caplin/trading/trademodel/TradeOnBehalfOfListener, suspending trading while TOBO user changes are occurring in the application.
