ABAP_EXEC
ABAP_DESCRIPTION
A reference to the class actor of the pesistent class
CL_SPFLI_PERSISTENT is assigned to the reference variable agent
. It is created once by the static constructor of the
CA_SPFLI_PERSISTENT class. Using the GET_PERSISTENT method, a check is made to establish whether there is already a persistent object with the required key in the database. If an object already exists, it can be deleted using DELETE_PERSISTENT . If no object exists, the exception CX_OS_OBJECT_NOT_FOUND occurs and is caught. In the corresponding CATCH block, an attempt is made using
CREATE_PERSISTENT to generate the object. Note that the object is only generated for the database when the COMMIT WORK statement is used. Without an explicit COMMIT WORK , it exists only as an administrating object in the program and it will be deleted without affecting the database at the end of the program.
