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_SHM_AREA is the superclass of all self-defined area classes.

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

Other versions: 7.31 | 7.40 | 7.54
