ABENSHM_CLASSES - SHM CLASSES

- 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

The 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 that must be implemented by the class for the optional area constructor:

IF_SHM_BUILD_INSTANCE

  |--Area Constructor Class
