Functionality

Generic locking of IF_PAK_WB_OBJECT_INTERNAL instances. The function module contains most of what is needed as an adapter between RS_ACCESS_PERMISSION and concrete IF_PAK_WB_OBJECT_INTERNAL instances. The only information required from specific adapters is the factory method to create specific IF_PAK_WB_OBJECT_INTERNAL instances (parameter IM_WB_OBJECT_PROVIDER).

Please note that, through IM_WB_OBJECT_PROVIDER, a static dependency is introduced to the class structure of the specific IF_PAK_WB_OBJECT_INTERNAL implementation. This means that PAK_LOCK_WB_OBJECT should not be called directly from the RS_ACCESS_PERMISSION subroutines.

The function module will make sure that, if an object is already locked, a CX_PAK_INVALID_STATE (corresponds to FOREIGN_LOCK) exception will be raised, no matter if the lock request came from the workbench's activation popup or from clients of an IF_PAK_WB_OBJECT instance, even if the object was locked from within the same session.
