This class provides functionality to call hooks. A hook is an extension point in the business logic, where you can register scripts to customize functionality.
This class does not have a constructor, so you cannot create it directly.

|---|---|
| static callHook(String, String, Object…) | Calls a hook on base of the specified extensionPoint and function. |
| static hasHook(String) | Checks whether a hook is registered or a system default implementation exists for this extension point. |

extensionPoint refers to the same name used to register a script as implementation. With this method it's only possible to check for a whole script registered but it is not possible to check, whether an individual function is implemented.

1dw.system.HookMgr.hasHook( "dw.order.calculate" );Parameters:
