Description

The class CL_DEMO_ABAP_MINI_DAEMON used by the program above demonstrates a mini ABAP daemon class. It implements only the following methods of the interface IF_ABAP_DAEMON_EXTENSION:

• ON_ACCEPT

In this method, the return value E_SETUP_MODE must be set, otherwise the daemon is not created. The method limits the creation of daemons to the program DEMO_ABAP_MINI_DAEMON.

• ON_MESSAGE

This method indicates that the daemon is reacting to message from a program. To enable this, the message is exported to the cross-transaction application buffer of the shared memory.

The program DEMO_ABAP_MINI_DAEMON uses the ABAP daemon manager to do the following:

• Start a daemon based on the class CL_DEMO_ABAP_MINI_DAEMON.

• Send a PCP message using a temporary ABAP daemon handle.

• Stop the daemon immediately, which is not a typical step.

It then checks whether the daemon wrote the message to the shared memory.
