Shared Objects - Classes and Interfaces
The hierarchy of global classes that are involved when working with shared objects is as follows:
CL_ABAP_MEMORY_AREA
|
|--CL_SHM_AREA
| |
| |--Area Classes
|
|--CL_IMODE_AREA
Meaning of the three predefined system classes:
- CL_ABAP_MEMORY_AREA is the superclass of all area classes.
- CL_SHM_AREA is the superclass of all self-defined area classes.
- CL_IMODE_AREA is a predefined area class for the internal session.
There is also a system interface, which must be implemented by the class for the optional area constructor:
IF_SHM_BUILD_INSTANCE
|
|--Area Constructor Class
